Vinorelbine 10 mg / ml Concentrate for solution for infusion





1. Name Of The Medicinal Product



Vinorelbine 10 mg/ml Concentrate for solution for infusion


2. Qualitative And Quantitative Composition



Vinorelbine (as tartrate) 10 mg/ml



Each 1 ml vial contains a total content of vinorelbine (as tartrate) of 10 mg



Each 5 ml vial contains a total content of vinorelbine (as tartrate) of 50 mg



For excipients, see section 6.1.



3. Pharmaceutical Form



Concentrate for solution for infusion



Clear, colourless to pale yellow solution.



4. Clinical Particulars



4.1 Therapeutic Indications



• As a single agent or in combination for the first line treatment of stage 3 or 4 non small cell lung cancer.



• Treatment of advanced breast cancer stage 3 and 4 relapsing after or refractory to an anthracycline containing regimen.



4.2 Posology And Method Of Administration



Vinorelbine must be administered under the supervision of a doctor experienced in the use of chemotherapy.



Strictly by intravenous injection through an infusion line.



The use of intrathecal route is contra-indicated.



In adults:



• Vinorelbine is usually given at 25-30 mg/m2 weekly.



Vinorelbine may be administered by slow bolus (5-10 minutes) after dilution in 20 – 50 ml of normal saline or glucose 50 mg/ml (5%) solution or by a short infusion (20-30 minutes) after dilution in 125 ml of normal saline or glucose 50 mg/ml (5%) solution. Administration should always be followed by a normal saline infusion to flush the vein.



Dose modifications:



Vinorelbine metabolism and clearance are mostly hepatic: only 18.5% is excreted unchanged in the urine. No prospective study relating altered metabolism of the active substance to its pharmacodynamic effects is available in order to establish guidelines for vinorelbine dose reduction in patients with impaired liver or kidney function.



Hepatic Impairment



In breast cancer-patients, vinorelbine clearance is not altered in the presence of moderate liver metastases (i.e. 75% of liver volume replaced by the tumour). In these patients, there is no pharmacokinetic rationale for reducing vinorelbine doses.



In patients with massive liver metastases (i.e.>75% of liver volume replaced by the tumour), the real impact of impaired drug elimination capacity of the liver has not been characterised. In these patients, it is empirically suggested that the dose be reduced by 1/3 and the haematological toxicity closely followed-up.



Renal impairment



There is no pharmacokinetic rationale for reducing vinorelbine dose in patients with impaired kidney function.



The dose limiting toxicity of vinorelbine is mainly neutropenia. This usually occurs between day 8 and day 12 after administration of the medicinal product, is short-lived, and is not cumulative. If the neutrophil count is <2000/mm³ and/or platelet number is <75000/mm³, then the treatment should be delayed until recovery. Administration of the medicinal product is expected to be delayed by 1 week in about 35% of treatment courses.



The maximum tolerated dose per administration: 35.4 mg/m² body surface area



The maximum total dose per administration: 60 mg



The safety and efficacy in children and adolescents have not been demonstrated.



4.3 Contraindications



- Hypersensitivity to vinorelbine or other vinca alkaloids



- Neutrophil count <2000/mm³ or severe current or recent infection (within the last 2 weeks)



- Platelet count less than 75.000/mm³



- Severe hepatic impairment not related to the tumoural process



- In combination with yellow fever vaccine



- Pregnancy (see section 4.6)



- Lactation (see section 4.6)



4.4 Special Warnings And Precautions For Use



- Vinorelbine must only be administered by the intravenous route. The use of intrathecal route is contra-indicated. Administration should always be followed by a normal saline infusion to flush the vein.



- Vinorelbine must be administered intravenously with great precision: It is very important to make sure that the cannula has been accurately placed into the vein before starting to infuse vinorelbine. If vinorelbine extravasates during intravenous administration, this can cause considerable local irritation. In this case, the infusion must be stopped immediately, the vein flushed through with physiological saline solution and the rest of the dose should be administered in another vein. In the event of extravasation glucosteroids can be given intravenously in order to reduce the risk of phlebitis.



- Treatment should be undertaken with close haematological monitoring (determination of haemoglobin level and number of leukocytes, granulocytes and platelets before each new injection). If the neutrophil count is <2000/mm³ and/or thrombocyte count is below 75000/mm³, treatment should be delayed until recovery and the patient should be observed (see section 4.2).



- If the patients present signs or symptoms suggestive of infection, a prompt investigation should be carried out.



- If there is significant hepatic impairment the dose should be reduced: caution is recommended and careful monitoring of haematological parameters required (see section 4.2).



- In case of renal impairment, because of the low level of renal excretion, no dose modification is necessary (see section 4.2 and 5.2).



- Vinorelbine should not be given concomitantly with radiotherapy if the treatment field includes the liver.



- This product is generally not recommended in combination with live attenuated vaccines.



- All contact with the eyes should be strictly avoided: risk of severe irritation and even corneal ulceration if the medicinal product is sprayed under pressure. Immediate liberal washing of the eye with normal saline solution should be undertaken if any contact occurs.



- Vinorelbine can have genotoxic effects. Therefore, men being treated with vinorelbine are advised not to father a child during and up to six months after treatment. Women of childbearing potential must use an effective method of contraception during treatment and three months thereafter.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



The combination of vinorelbine and cisplatin (a very common combination) does not affect the pharmacokinetic parameters. However, there is an increased incidence of granulocytopenia in the combination of vinorelbine and cisplatin than in vinorelbine as monotherapy.



As the metabolism of vinorelbine mainly involves CYP3A4, combinations with inductors (e.g. phenytoin, rifampicin) or inhibitors of this enzyme (e.g. itraconazole, ketoconazole) can modify the pharmacokinetics of vinorelbine.



Concomitant use of vinca alkaloids and mitomycin C increases the risk of bronchospasm and dyspnoea. In rare cases, particularly in combination with mitomycin, an interstitial pneumonitis has been observed.



Vinorelbine is a P-glycoprotein substrate and concomitant use with inhibitors or inducers of this transport protein can affect the concentration of vinorelbine.



4.6 Pregnancy And Lactation



- Pregnancy



There are insufficient data from the use of vinorelbine in pregnant women. In animal reproductive studies vinorelbine was embryo- and feto-lethal and teratogenic. Women should not become pregnant during treatment with vinorelbine. This product should not be used during pregnancy. If pregnancy should occur during the treatment, the possibility of genetic counselling should be considered.



Women of childbearing potential must be advised to use effective contraception during treatment and three months thereafter and should inform their doctor if they become pregnant.



- Lactation



There are no data on the excretion of vinorelbine into breast milk. Breast-feeding must therefore be discontinued before treatment with this medicinal product.



4.7 Effects On Ability To Drive And Use Machines



No studies of the effects on the ability to drive and use machines have been performed.



4.8 Undesirable Effects



Bone marrow toxicity and gastrointestinal symptoms are the most frequent and relevant undesirable effects of vinorelbine in monotherapy and combined therapy.



In combined chemotherapy of vinorelbine with other antineoplastic medicinal products it has to be considered, that the listed undesirable effect can occur more frequently and more severe than those undesirable effects observed during and after monotherapy. Moreover, the additional specific undesirable effects of the other medicinal products have to be considered.

Grades (G) of toxicity according to WHO classification



Infections and infestations



- Infections can develop commonly, mainly due to bone marrow suppression.



Blood and lymphatic system disorders



- The limiting toxicity is bone marrow depression which is manifested, in particular, as neutropenia (G1: 9.7%; G2: 15.2%; G3: 24.3%, G4: 27.8%), which is reversible within 5-7 days and non-cumulative; the neutrophil count is usually at its lowest 7-14 days after administration.



- Febrile neutropenia and neutropenic sepsis which in some cases (1.2%) had a fatal outcome can occur.



- Anaemia (G1-2: 61.2%; G3-4: 7.4% in monotherapy) and thrombocytopenia (G1-2: 5.1%; G3-4: 2.5% in monotherapy) can occur but are rarely severe.



Immune system disorders



- Allergic reactions (skin reactions, respiratory reactions) are common.



Metabolism and nutrition disorders



- Rare cases of severe hyponatraemia and in very rare cases SIADH-syndrome (syndrome of inappropriate antidiuretic hormone secretion) have been reported.



Nervous system disorders



Peripheral nervous system



Neurological conditions will normally be restricted to loss of deep tendon reflexes.



Development of severe paraesthesias, neurosensory and neuromotor disorders can occur (G1: 17.2%, G2: 3.6%, G3: 2.6%, G4: 0.1%). Very rarely Guillain-Barré syndrome.



Weakness of the lower extremities has been reported after long-term treatment. These symptoms are generally reversible.



Autonomic nervous system



The main symptom is constipation due to intestinal paresis (G1: 16.9%; G2: 4.9%; G3: 2%; G4: 0.7%), but it rarely progresses to paralytic ileus (see also “Gastrointestinal disorders”). The incidence of such reactions can increase when vinorelbine is combined with other chemotherapy.



Cardiac disorders



- Ischaemic heart disease (angina pectoris and/or transitory electrocardiogram modifications, myocardial infarction) has been reported in rare cases.



Respiratory system, thoracic and mediastinal disorders



- As with other vinca alkaloids, vinorelbine can cause dyspnoea and bronchospasm. Rare cases of interstitial lung disease have been reported, especially in patients treated with vinorelbine in combination with mitomycin.



Gastrointestinal disorders



- Very commonly nausea and vomiting is observed (G1: 19.9%; G2: 8.3%). Severe nausea and vomiting can occur commonly (G3: 1.9%; G4: 0.3%). The incidence of nausea and vomiting can increase when vinorelbine is combined with other chemotherapy. Antiemetic treatment can reduce the frequency.



- Constipation and paralytic ileus (see also “Autonomous nervous system”). The treatment can be resumed after recovery of normal intestinal function.



- Stomatitis as well as diarrhoea (G1: 7.6%; G2: 3.6%; G3: 0.7%; G4: 0.1%) and oesophagitis can occur. Severe diarrhoea is uncommon.



- Anorexia is observed very commonly (G1-2: 14%; G3: 1%).



- Rare cases of pancreatitis have been reported.



Hepatobiliary disorders



Temporary elevation of liver parameters without clinical symptoms has been reported: total bilirubin, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase.



Skin and subcutaneous tissue disorders



Mild alopecia may commonly occur which progresses if the treatment is continued (G1-2: 21%; G3-4: 4.1% in monotherapy). Commonly vinorelbine can cause skin reactions and in rare cases generalised skin reactions.



Musculoskeletal and connective tissue disorders



Arthralgia including jaw pain and myalgia have been reported in patients being treated with vinorelbine.



Renal and urinary disorders



Increased blood creatinine was observed commonly.



General disorders and administration site conditions



Patients being treated with vinorelbine can have fatigue, asthenia, fever and pain in different locations such as chest pain and pain in the tumor.



Reactions at the injection site can include erythema, smarting pains, discoloration of the vein and local phlebitis (G1: 12.3%; G2: 8.2%, G3: 3.6%; G4: 0.1% in monotherapy). As other vinca alkaloids vinorelbine has vesicant power. In rare cases local necrosis due to extravasation has been observed. This undesirable effect can be limited by correct positioning of the intravenous cannula or catheter and bolus injection, followed by liberal flushing of the vein.



4.9 Overdose



Cases of accidental acute overdose have been reported in humans: Such cases can result in bone marrow hypoplasia and are sometimes associated with infection, fever and paralytic ileus. Supporting treatment such as blood transfusion or broad-spectrum antibiotic treatment is normally initiated at the doctor's discretion. There is no known antidote.



As there is no specific antidote for the overdosage of vinorelbine given intravenously, symptomatic measures are necessary in case of an overdosage, e.g.:



- Continuous control of vital signs and careful monitoring of the patient.



- Daily control of blood count to observe the need of blood transfusions, of growth factors and to detect the need of intensive care and to minimize the risk of infections.



- Measures for prevention or for therapy of paralytic ileus



- Control of circulation system and of liver function



- Broad spectrum antibiotic therapy may be necessary in case of complications due to infections. In case of a paralytic ileus, decompression by a probe may be necessary.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Antineoplastic and immunmodulating agents, vinca alkaloids



ATC code: L 01 CA 04



Vinorelbine is an antineoplastic active substance of the vinca alkaloid family, but in contrast to all other vinca alkaloids the catharanthine portion of vinorelbine has undergone a structural modification. On the molecular level it affects the dynamic equilibrium of tubulin in the microtubular system of the cell.



Vinorelbine inhibits tubulin polymerisation and binds preferentially to mitotic microtubules, only affecting axonal microtubules at high concentrations. Spiralisation of the tubulin is induced to a lesser degree than with vincristine. Vinorelbine blocks mitosis in phase G2-M, causing cell death in interphase or at the following mitosis.



5.2 Pharmacokinetic Properties



After intravenous bolus injection or infusion in patients, the plasma concentration of vinorelbine is characterised by a three exponential elimination curve. The terminal elimination phase reflects a long half-life greater than 40 hours. Total clearance of vinorelbine is high (0.97-1.26 l/h/kg).



The active ingredient is widely distributed in the body with a volume of distribution ranging from 25.4-40.1 l/kg. Penetration of vinorelbine into pulmonary tissue is significant with tissue/plasma concentration ratios of greater than 300 in a study involving surgical biopsy. There is moderate binding to plasma proteins (13.5 %) but strong binding to platelets (78%). Linear pharmacokinetics have been shown for intravenously administered vinorelbine up to a dose of 45 mg/m².



Vinorelbine is primarily metabolised by CYP3A4 of cytochrome P450. All metabolites have been identified and none are active with the exception of 4-O-deacetylvinorelbine, which is the principal metabolite in the blood.



Renal elimination is low (<20% of the dose). Small concentrations of deacetyl vinorelbine have been recovered in humans, but vinorelbine is principally detected as the unchanged compound in urine. Elimination of the active substance is mainly via the bile duct and consists of the metabolites and mainly of unchanged vinorelbine.



The effect of kidney dysfunction on the disposition of vinorelbine has not been studied, but dose reduction is not indicated because of the low degree of renal excretion. In patients with liver metastases changes only occurred in the mean clearance of vinorelbine when over 75% of the liver was affected. In 6 cancer patients with moderate liver dysfunction (bilirubin



5.3 Preclinical Safety Data



The limiting toxicity in animals is bone marrow depression. In animal studies, vinorelbine induced aneuploidy and polyploidy.



It can be assumed that vinorelbine can also cause genotoxic effects in humans (induction of aneuploidy and polyploidy).



The results of studies for carcinogenic potential in mice and rats were negative but only low doses have been tested.



In animal reproductive studies, effects were observed at subtherapeutic dosages. Embryo- and fetotoxicity were seen, such as intra-uterine growth retardation and delayed ossification. Teratogenicity (fusion of the vertebrae, missing ribs) was observed at maternally toxic doses. In addition, spermatogenesis and secretion of prostate and seminal vesicles were reduced, but fertility in rats was not diminished.

Posology in adults



Treatment of duodenal ulcers



The recommended dose in patients with an active duodenal ulcer is 20 mg omeprazole once daily. In most patients healing occurs within two weeks. For those patients who may not be fully healed after the initial course, healing usually occurs during a further two weeks treatment period. In patients with poorly responsive duodenal ulcer 40 mg omeprazole once daily is recommended and healing is usually achieved within four weeks.



Prevention of relapse of duodenal ulcers



For the prevention of relapse of duodenal ulcer in H. pylori negative patients or when H. pylori eradication is not possible the recommended dose is 20 mg omeprazole once daily. In some patients a daily dose of 10 mg may be sufficient. In case of therapy failure, the dose can be increased to 40 mg.



Treatment of gastric ulcers



The recommended dose is 20 mg omeprazole once daily. In most patients healing occurs within four weeks. For those patients who may not be fully healed after the initial course, healing usually occurs during a further four weeks treatment period. In patients with poorly responsive gastric ulcer 40 mg omeprazole once daily is recommended and healing is usually achieved within eight weeks.



Prevention of relapse of gastric ulcers



For the prevention of relapse in patients with poorly responsive gastric ulcer the recommended dose is 20 mg omeprazole once daily. If needed the dose can be increased to 40 mg omeprazole once daily.



H. pylori eradication in peptic ulcer disease



For the eradication of H. pylori the selection of antibiotics should consider the individual patient's drug tolerance, and should be undertaken in accordance with national, regional and local resistance patterns and treatment guidelines.



• omeprazole 20 mg + clarithromycin 500 mg + amoxicillin 1,000 mg, each twice daily for one week, or



• omeprazole 20 mg + clarithromycin 250 mg (alternatively 500 mg) + metronidazole 400 mg (or 500 mg or tinidazole 500 mg), each twice daily for one week or



• omeprazole 40 mg once daily with amoxicillin 500 mg and metronidazole 400 mg (or 500 mg or tinidazole 500 mg), both three times a day for one week.



In each regimen, if the patient is still H. pylori positive, therapy may be repeated.



Treatment of NSAID-associated gastric and duodenal ulcers



For the treatment of NSAID-associated gastric and duodenal ulcers, the recommended dose is 20 mg omeprazole once daily. In most patients healing occurs within four weeks. For those patients who may not be fully healed after the initial course, healing usually occurs during a further four weeks treatment period.



Prevention of NSAID-associated gastric and duodenal ulcers in patients at risk



For the prevention of NSAID-associated gastric ulcers or duodenal ulcers in patients at risk (age > 60, previous history of gastric and duodenal ulcers, previous history of upper GI bleeding) the recommended dose is 20 mg omeprazole once daily.



Treatment of reflux esophagitis



The recommended dose is 20 mg omeprazole once daily. In most patients healing occurs within four weeks. For those patients who may not be fully healed after the initial course, healing usually occurs during a further four weeks treatment period.



In patients with severe esophagitis 40 mg omeprazole once daily is recommended and healing is usually achieved within eight weeks.



Long-term management of patients with healed reflux esophagitis



For the long-term management of patients with healed reflux esophagitis the recommended dose is 10 mg omeprazole once daily. If needed, the dose can be increased to 20-40 mg omeprazole once daily.



Treatment of symptomatic gastro-esophageal reflux disease



The recommended dose is 20 mg omeprazole daily. Patients may respond adequately to 10 mg daily, and therefore individual dose adjustment should be considered.



If symptom control has not been achieved after four weeks treatment with 20 mg omeprazole daily, further investigation is recommended.



Treatment of Zollinger-Ellison syndrome



In patients with Zollinger-Ellison syndrome the dose should be individually adjusted and treatment continued as long as clinically indicated. The recommended initial dose is 60 mg omeprazole daily. All patients with severe disease and inadequate response to other therapies have been effectively controlled and more than 90% of the patients maintained on doses of 20-120 mg omeprazole daily. When the dose exceeds 80 mg omeprazole daily, the dose should be divided and given twice daily.

Impaired hepatic function



In patients with impaired hepatic function a daily dose of 10–20 mg may be sufficient (see section 5.2).



Elderly (> 65 years old)



Dose adjustment is not needed in the elderly (see section 5.2).



Method of administration



It is recommended to take omeprazole capsules in the morning, preferably without food, swallowed whole with half a glass of water. The capsules must not be chewed or crushed.



For patients with swallowing difficulties and for children who can drink or swallow semi-solid food



Patients can open the capsule and swallow the contents with half a glass of water or after mixing the contents in a slightly acidic fluid e.g., fruit juice or applesauce, or in non-carbonated water. Patients should be advised that the dispersion should be taken immediately (or within 30 minutes) and always be stirred just before drinking and rinsed down with half a glass of water.



Alternatively patients can suck the capsule and swallow the pellets with half a glass of water. The enteric-coated pellets must not be chewed.



4.3 Contraindications



Hypersensitivity to omeprazole, substituted benzimidazoles or to any of the excipients.



Omeprazole like other proton pump inhibitors (PPIs) must not be used concomitantly with nelfinavir (see section 4.5).



4.4 Special Warnings And Precautions For Use



In the presence of any alarm symptom (e.g. significant unintentional weight loss, recurrent vomiting, dysphagia, haematemesis or melena) and when gastric ulcer is suspected or present, malignancy should be excluded, as treatment may alleviate symptoms and delay diagnosis.



Co-administration of atazanavir with proton pump inhibitors is not recommended (see section 4.5). If the combination of atazanavir with a proton pump inhibitor is judged unavoidable, close clinical monitoring (e.g virus load) is recommended in combination with an increase in the dose of atazanavir to 400 mg with 100 mg of ritonavir; omeprazole 20 mg should not be exceeded.



Omeprazole, as all acid-blocking medicines, may reduce the absorption of vitamin B12 (cyanocobalamin) due to hypo- or achlorhydria. This should be considered in patients with reduced body stores or risk factors for reduced vitamin B12 absorption on long-term therapy.



Omeprazole is a CYP2C19 inhibitor. When starting or ending treatment with omeprazole, the potential for interactions with drugs metabolised through CYP2C19 should be considered. An interaction is observed between clopidogrel and omeprazole (see section 4.5). The clinical relevance of this interaction is uncertain. As a precaution, concomitant use of omeprazole and clopidogrel should be discouraged.



Some children with chronic illnesses may require long-term treatment although it is not recommended.



Treatment with proton pump inhibitors may lead to slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter (see section 5.1).



As in all long-term treatments, especially when exceeding a treatment period of 1 year, patients should be kept under regular surveillance.



This medicinal product contains lactose. Therefore patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Effects of omeprazole on the pharmacokinetics of other active substances

The plasma levels of nelfinavir and atazanavir are decreased in case of co-administration with omeprazole.



Concomitant administration of omeprazole with nelfinavir is contraindicated (see section 4.3). Co-administration of omeprazole (40 mg once daily) reduced mean nelvinavir exposure by ca. 40% and the mean exposure of the pharmacologically active metabolite M8 was reduced by ca. 75 –90%. The interaction may also involve CYP2C19 inhibition.



Concomitant administration of omeprazole with atazanavir is not recommended (see section 4.4). Concomitant administration of omeprazole (40 mg once daily) and atazanavir 300 mg/ritonavir 100 mg to healthy volunteers resulted in a 75% decrease of the atazanavir exposure. Increasing the atazanavir dose to 400 mg did not compensate for the impact of omeprazole on atazanavir exposure. The co-administration of omeprazole (20 mg once daily) with atazanavir 400 mg/ritonavir 100 mg to healthy volunteers resulted in a decrease of approximately 30% in the atazanavir exposure as compared to atazanavir 300 mg/ritonavir 100 mg once daily.



Digoxin



Concomitant treatment with omeprazole (20 mg daily) and digoxin in healthy subjects increased the bioavailability of digoxin by 10%. Digoxin toxicity has been rarely reported. However caution should be exercised when omeprazole is given at high doses in elderly patients. Therapeutic drug monitoring of digoxin should be then reinforced.



Clopidogrel



In a crossover clinical study, clopidogrel (300 mg loading dose followed by 75 mg/day) alone and with omeprazole (80 mg at the same time as clopidogrel) were administered for 5 days. The exposure to the active metabolite of clopidogrel was decreased by 46% (Day 1) and 42% (Day 5) when clopidogrel and omeprazole were administered together. Mean inhibition of platelet aggregation (IPA) was diminished by 47% (24 hours) and 30% (Day 5) when clopidogrel and omeprazole were administered together. In another study it was shown that administering clopidogrel and omeprazole at different times did not prevent their interaction that is likely to be driven by the inhibitory effect of omeprazole on CYP2C19. Inconsistent data on the clinical implications of this PK/PD interaction in terms of major cardiovascular events have been reported from observational and clinical studies.



Other active substances



The absorption of posaconazole, erlotinib, ketoconazol and itraconazol is significantly reduced and thus clinical efficacy may be impaired. For posaconazole and erlotinib concomitant use should be avoided.



Active substances metabolised by CYP2C19



Omeprazole is a moderate inhibitor of CYP2C19, the major omeprazole metabolising enzyme. Thus, the metabolism of concomitant active substances also metabolised by CYP2C19, may be decreased and the systemic exposure to these substances increased. Examples of such drugs are R-warfarin and other vitamin K antagonists, cilostazol, diazepam and phenytoin.



Cilostazol



Omeprazole, given in doses of 40 mg to healthy subjects in a cross-over study, increased Cmax and AUC for cilostazol by 18% and 26% respectively, and one of its active metabolites by 29% and 69% respectively.



Phenytoin



Monitoring phenytoin plasma concentration is recommended during the first two weeks after initiating omeprazole treatment and, if a phenytoin dose adjustment is made, monitoring and a further dose adjustment should occur upon ending omeprazole treatment.



Unknown mechanism



Saquinavir



Concomitant administration of omeprazole with saquinavir/ritonavir resulted in increased plasma levels up to approximately 70% for saquinavir associated with good tolerability in HIV-infected patients.



Tacrolimus



Concomitant administration of omeprazole has been reported to increase the serum levels of tacrolimus. A reinforced monitoring of tacrolimus concentrations as well as renal function (creatinine clearance) should be performed, and dosage of tacrolimus adjusted if needed.



Effects of other active substances on the pharmacokinetics of omeprazole



Inhibitors CYP2C19 and/or CYP3A4



Since omeprazole is metabolised by CYP2C19 and CYP3A4, active substances known to inhibit CYP2C19 or CYP3A4 (such as clarithromycin and voriconazole) may lead to increased omeprazole serum levels by decreasing omeprazole's rate of metabolism. Concomitant voriconazole treatment resulted in more than doubling of the omeprazole exposure. As high doses of omeprazole have been well-tolerated adjustment of the omeprazole dose is not generally required. However, dose adjustment should be considered in patients with severe hepatic impairment and if long-term treatment is indicated.



Inducers of CYP2C19 and/or CYP3A4



Active substances known to induce CYP2C19 or CYP3A4 or both (such as rifampicin and St John's wort) may lead to decreased omeprazole serum levels by increasing omeprazole's rate of metabolism.



4.6 Pregnancy And Lactation



Results from three prospective epidemiological studies (more than 1000 exposed outcomes) indicate no adverse effects of omeprazole on pregnancy or on the health of the foetus/newborn child. Omeprazole can be used during pregnancy.



Omeprazole is excreted in breast milk but is not likely to influence the child when therapeutic doses are used.



4.7 Effects On Ability To Drive And Use Machines



Omeprazole is not likely to affect the ability to drive or use machines. Adverse drug reactions such as dizziness and visual disturbances may occur (see section 4.8). If affected, patients should not drive or operate machinery.



4.8 Undesirable Effects



The most common side effects (1-10% of patients) are headache, abdominal pain, constipation, diarrhoea, flatulence and nausea/vomiting.



The following adverse drug reactions have been identified or suspected in the clinical trials programme for omeprazole and post-marketing. None was found to be dose-related.

Paediatric population



The safety of omeprazole has been assessed in a total of 310 children aged 0 to 16 years with acid-related disease. There are limited long term safety data from 46 children who received maintenance therapy of omeprazole during a clinical study for severe erosive esophagitis for up to 749 days. The adverse event profile was generally the same as for adults in short- as well as in long-term treatment. There are no long term data regarding the effects of omeprazole treatment on puberty and growth.



4.9 Overdose



There is limited information available on the effects of overdoses of omeprazole in humans. In the literature, doses of up to 560 mg have been described, and occasional reports have been received when single oral doses have reached up to 2,400 mg omeprazole (120 times the usual recommended clinical dose). Nausea, vomiting, dizziness, abdominal pain, diarrhoea and headache have been reported. Also apathy, depression and confusion have been described in single cases.



The symptoms described have been transient, and no serious outcome has been reported. The rate of elimination was unchanged (first order kinetics) with increased doses. Treatment, if needed, is symptomatic.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Drugs for peptic ulcer and gastro-oesophageal reflux disease, proton pump inhibitors, ATC code: A02BC01



Mechanism of action



Omeprazole, a racemic mixture of two enantiomers reduces gastric acid secretion through a highly targeted mechanism of action. It is a specific inhibitor of the acid pump in the parietal cell. It is rapidly acting and provides control through reversible inhibition of gastric acid secretion with once daily dosing.



Omeprazole is a weak base and is concentrated and converted to the active form in the highly acidic environment of the intracellular canaliculi within the parietal cell, where it inhibits the enzyme H+ K+-ATPase - the acid pump. This effect on the final step of the gastric acid formation process is dose-dependent and provides for highly effective inhibition of both basal acid secretion and stimulated acid secretion, irrespective of stimulus.



Pharmacodynamic effects



All pharmacodynamic effects observed can be explained by the effect of omeprazole on acid secretion.



Effect on gastric acid secretion



Oral dosing with omeprazole once daily provides for rapid and effective inhibition of daytime and night-time gastric acid secretion with maximum effect being achieved within 4 days of treatment. With omeprazole 20 mg, a mean decrease of at least 80% in 24-hour intragastric acidity is then maintained in duodenal ulcer patients, with the mean decrease in peak acid output after pentagastrin stimulation being about 70% 24 hours after dosing.



Oral dosing with omeprazole 20 mg maintains an intragastric pH of



As a consequence of reduced acid secretion and intragastric acidity, omeprazole dose-dependently reduces/normalizes acid exposure of the esophagus in patients with gastro-esophageal reflux disease. The inhibition of acid secretion is related to the area under the plasma concentration-time curve (AUC) of omeprazole and not to the actual plasma concentration at a given time.



No tachyphylaxis has been observed during treatment with omeprazole.



Effect on H. pylori



H. pylori is associated with peptic ulcer disease, including duodenal and gastric ulcer disease. H. pylori is a major factor in the development of gastritis. H. pylori together with gastric acid are major factors in the development of peptic ulcer disease. H. pylori is a major factor in the development of atrophic gastritis which is associated with an increased risk of developing gastric cancer.



Eradication of H. pylori with omeprazole and antimicrobials is associated with high rates of healing and long-term remission of peptic ulcers.



Dual therapies have been tested and found to be less effective than triple therapies. They could, however, be considered in cases where known hypersensitivity precludes use of any triple combination.



Other effects related to acid inhibition



During long-term treatment gastric glandular cysts have been reported in a somewhat increased frequency. These changes are a physiological consequence of pronounced inhibition of acid secretion, are benign and appear to be reversible.



Decreased gastric acidity due to any means including proton pump inhibitors, increases gastric counts of bacteria normally present in the gastrointestinal tract. Treatment with acid-reducing drugs may lead to slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter.



Paediatric use



In a non-controlled study in children (1 to 16 years of age) with severe reflux esophagitis, omeprazole at doses of 0.7 to 1.4 mg/kg improved esophagitis level in 90% of the cases and significantly reduced reflux symptoms. In a single-blind study, children aged 0–24 months with clinically diagnosed gastro-esophageal reflux disease were treated with 0.5, 1.0 or 1.5 mg omeprazole/kg. The frequency of vomiting/regurgitation episodes decreased by 50% after 8 weeks of treatment irrespective of the dose.



Eradication of H. pylori in children



A randomised, double blind clinical study (Héliot study) concluded that omeprazole in combination with two antibiotics (amoxicillin and clarithromycin), was safe and effective in the treatment of H. pylori infection in children age 4 years old and above with gastritis: H. pylori eradication rate: 74.2% (23/31 patients) with omeprazole + amoxicillin + clarithromycin versus 9.4% (3/32 patients) with amoxicillin + clarithromycin. However, there was no evidence of any clinical benefit with respect to dyspeptic symptoms. This study does not support any information for children aged less than 4 years.



5.2 Pharmacokinetic Properties



Absorption



Omeprazole and omeprazole magnesium are acid labile and are therefore administered orally as enteric-coated granules in capsules or tablets. Absorption of omeprazole is rapid, with peak plasma levels occurring approximately 1-2 hours after dose. Absorption of omeprazole takes place in the small intestine and is usually completed within 3-6 hours. Concomitant intake of food has no influence on the bioavailability. The systemic availability (bioavailability) from a single oral dose of omeprazole is approximately 40%. After repeated once-daily administration, the bioavailability increases to about 60%.



Distribution



The apparent volume of distribution in healthy subjects is approximately 0.3 l/kg body weight. Omeprazole is 97% plasma protein bound.



Metabolism



Omeprazole is completely metabolised by the cytochrome P450 system (CYP). The major part of its metabolism is dependent on the polymorphically expressed CYP2C19, responsible for the formation of hydroxyomeprazole, the major metabolite in plasma. The remaining part is dependent on another specific isoform, CYP3A4, responsible for the formation of omeprazole sulphone. As a consequence of high affinity of omeprazole to CYP2C19, there is a potential for competitive inhibition and metabolic drug-drug interactions with other substrates for CYP2C19. However, due to low affinity to CYP3A4, omeprazole has no potential to inhibit the metabolism of other CYP3A4 substrates. In addition, omeprazole lacks an inhibitory effect on the main CYP enzymes.



Approximately 3% of the Caucasian population and 15-20% of Asian populations lack a functional CYP2C19 enzyme and are called poor metabolisers. In such individuals the metabolism of omeprazole is probably mainly catalysed by CYP3A4. After repeated once-daily administration of 20 mg omeprazole, the mean AUC was 5 to 10 times higher in poor metabolisers than in subjects having a functional CYP2C19 enzyme (extensive metabolisers). Mean peak plasma concentrations were also higher, by 3 to 5 times. These findings have no implications for the posology of omeprazole.



Excretion



The plasma elimination half-life of omeprazole is usually shorter than one hour both after single and repeated oral once-daily dosing. Omeprazole is completely eliminated from plasma between doses with no tendency for accumulation during once-daily administration. Almost 80% of an oral dose of omeprazole is excreted as metabolites in the urine, the remainder in the faeces, primarily originating from bile secretion.



The AUC of omeprazole increases with repeated administration. This increase is dose-dependent and results in a non-linear dose-AUC relationship after repeated administration. This time- and dose-dependency is due to a decrease of first pass metabolism and systemic clearance probably caused by an inhibition of the CYP2C19 enzyme by omeprazole and/or its metabolites (e.g. the sulphone).



No metabolite has been found to have any effect on gastric acid secretion.



Special populations



Impaired hepatic function



The metabolism of omeprazole in patients with liver dysfunction is impaired, resulting in an increased AUC. Omeprazole has not shown any tendency to accumulate with once daily dosing.



Impaired renal function



The pharmacokinetics of omeprazole, including systemic bioavailability and elimination rate, are unchanged in patients with reduced renal function.



Elderly



The metabolism rate of omeprazole is somewhat reduced in elderly subjects (75-79 years of age).



Paediatric patients



During treatment with the recommended doses to children from the age of 1 year, similar plasma concentrations were obtained as compared to adults. In children younger than 6 months, clearance of omeprazole is low due to low capacity to metabolise omeprazole.



5.3 Preclinical Safety Data



Gastric ECL-cell hyperplasia and carcinoids, have been observed in life-long studies in rats treated with omeprazole. These changes are the result of sustained hypergastrinaemia secondary to acid inhibition. Similar findings have been made after treatment with H2-receptor antagonists, proton pump inhibitors and after partial fundectomy. Thus, these changes are not from a direct effect of any individual active substance.

1. Name Of The Medicinal Product



Montelukast 10 mg film-coated tablets


2. Qualitative And Quantitative Composition



Each film-coated tablet contains montelukast sodium 10.4 mg equivalent to 10 mg montelukast.



Excipients: Contain 130.95 mg of Lactose monohydrate per tablet



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Film-coated tablet



7.9 x 7.9 mm beige coloured, rounded square, biconvex, film coated tablet debossed “M10” on one side and plain on other side.



4. Clinical Particulars



4.1 Therapeutic Indications



Montelukast 10 mg film-coated tablets is indicated in the treatment of asthma as add-on therapy in adults and adolescents from 15 years of age and older with mild to moderate persistent asthma who are inadequately controlled on inhaled corticosteroids and in whom “as-needed” short acting beta-agonists provide inadequate clinical control of asthma. In those asthmatic patients in whom Montelukast 10 mg film-coated tablets is indicated in asthma, Montelukast 10 mg film-coated tablets can also provide symptomatic relief of seasonal allergic rhinitis.



Montelukast 10 mg film-coated tablets is also indicated in the prophylaxis of asthma in which the predominant component is exercise-induced bronchoconstriction.



4.2 Posology And Method Of Administration



Method of administration:



For oral use.



Posology:



The dosage for adults and adolescents 15 years of age and older with asthma, or with asthma and concomitant seasonal allergic rhinitis, is one 10 mg tablet daily to be taken in the evening.



General recommendations:



The therapeutic effect of Montelukast 10 mg film-coated tablets on parameters of asthma control occurs within one day. Montelukast 10 mg film-coated tablets may be taken with or without food. Patients should be advised to continue taking Montelukast 10 mg film-coated tablets even if their asthma is under control, as well as during periods of worsening asthma. Montelukast 10 mg film-coated tablets should not be used concomitantly with other products containing the same active ingredient, montelukast.



No dosage adjustment is necessary for the elderly, or for patients with renal insufficiency, or mild to moderate hepatic impairment. There are no data on patients with severe hepatic impairment. The dosage is the same for both male and female patients.



Therapy with Montelukast 10 mg film-coated tablets in relation to other treatments for asthma.



Montelukast 10 mg film-coated tablets can be added to a patient's existing treatment regimen.



Inhaled corticosteroids:



Treatment with Montelukast 10 mg film-coated tablets can be used as add-on therapy in patients when inhaled corticosteroids plus "as needed" short acting beta-agonists provide inadequate clinical control. Montelukast 10 mg film-coated tablets should not be abruptly substituted for inhaled corticosteroids (see section 4.4).



10 mg film-coated tablets are available for adults and adolescents above 15 years old.



Other available strengths/pharmaceutical forms:



5 mg chewable tablets are available for paediatric and adolescents patients 6 to 14 years of age.



4 mg chewable tablets are available for paediatric patients 2 to 5 years of age.



4.3 Contraindications



Hypersensitivity to the active substance or to any of the excipients.



4.4 Special Warnings And Precautions For Use



Patients should be advised never to use oral montelukast to treat acute asthma attacks and to keep their usual appropriate rescue medication for this purpose readily available. If an acute attack occurs, a short-acting inhaled beta-agonist should be used. Patients should seek their doctor's advice as soon as possible if they need more inhalations of short-acting beta-agonists than usual.



Montelukast should not be substituted abruptly for inhaled or oral corticosteroids.



There are no data demonstrating that oral corticosteroids can be reduced when montelukast is given concomitantly.



In rare cases, patients on therapy with anti-asthma agents including montelukast may present with systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, a condition which is often treated with systemic corticosteroid therapy. These cases usually, but not always, have been associated with the reduction or withdrawal of oral corticosteroid therapy. The possibility that leukotriene receptor antagonists may be associated with emergence of Churg-Strauss syndrome can neither be excluded nor established. Physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients. Patients who develop these symptoms should be reassessed and their treatment regimens evaluated.



Treatment with montelukast does not alter the need for patients with aspirin-sensitive asthma to avoid taking aspirin and other non-steroidal anti-inflammatory drugs.



This medicinal product contains lactose monohydrate.



Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Montelukast may be administered with other therapies routinely used in the prophylaxis and chronic treatment of asthma. In drug-interactions studies, the recommended clinical dose of montelukast did not have clinically important effects on the pharmacokinetics of the following medicinal products: theophylline, prednisone, prednisolone, oral contraceptives (ethinyl estradiol/ norethindrone 35/1), terfenadine, digoxin and warfarin.



The area under the plasma concentration curve (AUC) for montelukast was decreased approximately 40% in subjects with coadministration of phenobarbital. Since montelukast is metabolised by CYP 3A4, caution should be exercised, particularly in children, when montelukast is co-administered with inducers of CYP 3A4, such as phenytoin, phenobarbital and rifampicin.



In vitro studies have shown that montelukast is a potent inhibitor of CYP 2C8. However, data from a clinical drug-drug interaction study involving montelukast and rosiglitazone (a probe substrate representative of medicinal products primarily metabolized by CYP 2C8) demonstrated that montelukast does not inhibit CYP 2C8 in vivo. Therefore, montelukast is not anticipated to markedly alter the metabolism of medicinal products metabolised by this enzyme (e.g., paclitaxel, rosiglitazone and repaglinide.)



4.6 Pregnancy And Lactation



Use during pregnancy



Animal studies do not indicate harmful effects with respect to effects on pregnancy or embryonal/foetal development.



Limited data from available pregnancy databases do not suggest a causal relationship between Montelukast 10 mg film-coated tablets and malformations (i.e. limb defects) that have been rarely reported in worldwide post marketing experience.



Montelukast 10 mg film-coated tablets may be used during pregnancy only if it is considered to be clearly essential.



Use during breastfeeding



It is unknown whether montelukast is excreted in human milk. Studies in rats have shown that montelukast is excreted in milk (see section 5.3).



Montelukast 10 mg film-coated tablets may be used in breast-feeding only if it is considered to be clearly essential



4.7 Effects On Ability To Drive And Use Machines



Montelukast is not expected to affect a patient's ability to drive a car or operate machinery. However, in very rare cases, individuals have reported drowsiness or dizziness.



4.8 Undesirable Effects



The frequency using the following convention: Common (



Montelukast has been evaluated in clinical studies as follows:



• 10 mg film-coated tablets in approximately 4000 adult asthmatic patients 15 years of age and older.



• 10 mg film-coated tablets in approximately 400 adult asthmatic patients with seasonal allergic rhinitis 15 years of age and older.



• 5 mg chewable tablets in approximately 1750 paediatric and adolescents asthmatic patients 6 to 14 years of age.



The following drug-related adverse reactions in clinical studies were reported commonly (

With prolonged treatment in clinical trials with a limited number of patients for up to 2 years for adults, and up to 12 months for paediatric and adolescents patients 6 to 14 years of age, the safety profile did not change.



The following adverse reactions have been reported in post-marketing use:



Infections and infestations: upper respiratory infection.



Blood and lymphatic system disorders: increased bleeding tendency.



Immune system disorders: hypersensitivity reactions including anaphylaxis, hepatic eosinophilic infiltration.



Psychiatric disorders: dream abnormalities including nightmares, hallucinations, insomnia, somnambulism, irritability, anxiety, restlessness, agitation including aggressive behaviour or hostility, tremor, depression, suicidal thinking and behaviour (suicidality) in very rare cases.

Gastro-intestinal disorders: diarrhoea, dry mouth, dyspepsia, nausea, vomiting.



Hepatobiliary disorders: elevated levels of serum transaminases (ALT, AST), hepatitis (including cholestatic, hepatocellular and mixed-pattern liver injury).



Skin and subcutaneous tissue disorders: angiooedema, bruising, urticaria, pruritus, rash, erythema nodosum.



Musculoskeletal and connective tissue disorders: arthralgia, myalgia including muscle cramps.



General disorders and administration site conditions: asthenia/fatigue, malaise, oedema, pyrexia.



Very rare cases of Churg-Strauss Syndrome (CSS) have been reported during montelukast treatment in asthmatic patients (see section 4.4).



4.9 Overdose



Symptoms



No specific information is available on the treatment of overdose with montelukast. In chronic asthma studies, montelukast has been administered at doses up to 200 mg/day to patients for 22 weeks and in short term studies, up to 900 mg/day to patients for approximately one week without clinically important adverse experiences.



There have been reports of acute overdose in post-marketing experience and clinical studies with montelukast. These include reports in adults and children with a dose as high as 1000 mg (approximately 61 mg/kg in a 42 month old child). The clinical and laboratory findings observed were consistent with the safety profile in adults and paediatric patients. There were no adverse experiences in the majority of overdose reports. The most frequently occurring adverse experiences were consistent with the safety profile of montelukast and included abdominal pain, somnolence, thirst, headache, vomiting and psychomotor hyperactivity.



Treatment



It is not known whether montelukast is dialysable by peritoneal- or haemo-dialysis.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Other systemic drugs for obstructive airway diseases, Leukotriene receptor antagonist



ATC code: R03D C03



The cysteinyl leukotrienes (LTC4, LTD4, LTE4) are potent inflammatory eicosanoids released from various cells including mast cells and eosinophils. These important pro-asthmatic mediators bind to cysteinyl leukotriene (CysLT) receptors. The CysLT type-1 (CysLT1) receptor is found in the human airway (including airway smooth muscle cells and airway macrophages) and on other pro-inflammatory cells (including eosinophils and certain myeloid stem cells). CysLTs have been correlated with the pathophysiology of asthma and allergic rhinitis. In asthma, leukotriene-mediated effects include bronchoconstriction, mucous secretion, vascular permeability, and eosinophil recruitment. In allergic rhinitis, CysLTs are released from the nasal mucosa after allergen exposure during both early- and late-phase reactions and are associated with symptoms of allergic rhinitis. Intranasal challenge with CysLTs has been shown to increase nasal airway resistance and symptoms of nasal obstruction.



Montelukast is an orally active compound which binds with high affinity and selectivity to the CysLT1 receptor. In clinical studies, montelukast inhibits bronchoconstriction due to inhaled LTD4 at doses as low as 5 mg. Bronchodilation was observed within 2 hours of oral administration. The bronchodilation effect caused by a beta agonist was additive to that caused by montelukast. Treatment with montelukast inhibited both early- and late phase bronchoconstriction due to antigen challenge. Montelukast, compared with placebo, decreased peripheral blood eosinophils in adult and paediatric patients. In a separate study, treatment with montelukast significantly decreased eosinophils in the airways (as measured in sputum) and in peripheral blood while improving clinical asthma control.



In studies in adults, montelukast, 10 mg once daily, compared with placebo, demonstrated significant improvements in morning FEV1 (10.4% vs 2.7% change from baseline), AM peak expiratory flow rate (PEFR) (24.5 L/min vs 3.3 L/min change from baseline), and significant decrease in total beta-agonist use ( -26.1% vs -4.6% change from baseline). Improvement in patient-reported daytime and nighttime asthma symptoms scores was significantly better than placebo.



Studies in adults demonstrated the ability of montelukast to add to the clinical effect of inhaled corticosteroid (% change from baseline for inhaled beclometasone plus ontelukast vs beclometasone, respectively for FEV1: 5.43% vs 1.04%; beta-agonist use: -8.70% vs 2.64%). Compared with inhaled beclometasone (200 µg twice daily with a spacer device), montelukast demonstrated a more rapid initial response, although over the 12-week study, beclometasone provided a greater average treatment effect (% change from baseline for montelukast vs beclometasone, respectively for FEV1: 7.49% vs 13.3%; beta agonist use: -28.28% vs -43.89%). However, compared with beclometasone, a high percentage of patients treated with montelukast achieved similar clinical responses (e.g., 50% of patients treated with beclometasone achieved an improvement in FEV1 of approximately 11% or more over baseline while approximately 42% of patients treated with montelukast achieved the same response).



A clinical study was conducted to evaluate montelukast for the symptomatic treatment of seasonal allergic rhinitis in adult asthmatic patients 15 years of age and older with concomitant seasonal allergic rhinitis. In this study, montelukast 10 mg tablets administered once daily demonstrated a statistically significant improvement in the Daily Rhinitis Symptoms score, compared with placebo. The Daily Rhinitis Symptoms score is the average of the Daytime Nasal Symptoms score (mean of nasal congestion, rhinorrhea, sneezing, nasal itching) and the Nighttime Symptoms score (mean of nasal congestion upon awakening, difficulty going to sleep, and nighttime awakenings scores). Global evaluations of allergic rhinitis by patients and physicians were significantly improved, compared with placebo. The evaluation of asthma efficacy was not a primary objective in this study.



In an 8-week study in paediatric patients 6 to 14 years of age, montelukast 5 mg once daily, compared with placebo, significantly improved respiratory function (FEV1 8.71% vs 4.16% change from baseline; AM PEFR 27.9 L/min vs 17.8 L/min change from baseline) and decreased "as-needed" beta-agonist use (-11.7% vs +8.2% change from baseline).



Significant reduction of exercise-induced bronchoconstriction (EIB) was demonstrated in a 12-week study in adults (maximal fall in FEV1 22.33% for montelukast vs 32.40% for placebo; time to recovery to within 5% of baseline FEV1 44.22 min vs 60.64 min). This effect was consistent throughout the 12-week study period. Reduction in EIB was also demonstrated in a short term study in paediatric patients (maximal fall in FEV1 18.27% vs 26.11%; time to recovery to within 5% of baseline FEV1 17.76 min vs 27.98 min). The effect in both studies was demonstrated at the end of the once-daily dosing interval.



In aspirin-sensitive asthmatic patients receiving concomitant inhaled and/or oral corticosteroids, treatment with montelukast, compared with placebo, resulted in significant improvement in asthma control (FEV1 8.55% vs -1.74% change from baseline and decrease in total beta-agonist use -27.78% vs 2.09% change from baseline).



5.2 Pharmacokinetic Properties



Absorption



Montelukast is rapidly absorbed following oral administration. For the 10 mg film-coated tablet, the mean peak plasma concentration (Cmax) is achieved 3 hours (Tmax) after administration in adults in the fasted state. The mean oral bioavailability is 64%. The oral bioavailability and Cmax are not influenced by a standard meal. Safety and efficacy were demonstrated in clinical trials where the 10 mg film-coated tablet was administered without regard to the timing of food ingestion.



For the 5 mg chewable tablet, the Cmax is achieved in 2 hours after administration in adults in the fasted state. The mean oral bioavailability is 73% and is decreased to 63% by a standard meal.



Distribution



Montelukast is more than 99% bound to plasma proteins. The steady-state volume of distribution of montelukast averages 8-11 litres. Studies in rats with radiolabelled montelukast indicate minimal distribution across the blood-brain barrier. In addition, concentrations of radiolabelled material at 24 hours post-dose were minimal in all other tissues.



Biotransformation



Montelukast is extensively metabolised. In studies with therapeutic doses, plasma concentrations of metabolites of montelukast are undetectable at steady state in adults and children.



In vitro studies using human liver microsomes indicate that cytochrome P450 3A4, 2A6 and 2C9 are involved in the metabolism of montelukast. Based on further in vitro results in human liver microsomes, therapeutic plasma concentrations of montelukast do not inhibit cytochromes P450 3A4, 2C9, 1A2, 2A6, 2C19, or 2D6. The contribution of metabolites to the therapeutic effect of montelukast is minimal.



Elimination



The plasma clearance of montelukast averages 45 ml/min in healthy adults. Following an oral dose of radiolabelled montelukast, 86% of the radioactivity was recovered in 5-day faecal collections and <0.2% was recovered in urine. Coupled with estimates of montelukast oral bioavailability, this indicates that montelukast and its metabolites are excreted almost exclusively via the bile.



Characteristics in patients



No dosage adjustment is necessary for the elderly or mild to moderate hepatic insufficiency. Studies in patients with renal impairment have not been undertaken. Because montelukast and its metabolites are eliminated by the biliary route, no dose adjustment is anticipated to be necessary in patients with renal impairment. There are no data on the pharmacokinetics of montelukast in patients with severe hepatic insufficiency (Child-Pugh score >9).



With high doses of montelukast (20- and 60-fold the recommended adult dose), decrease in plasma theophylline concentration was observed. This effect was not seen at the recommended dose of 10 mg once daily.



5.3 Preclinical Safety Data



In animal toxicity studies, minor serum biochemical alterations in ALT, glucose, phosphorus and triglycerides were observed which were transient in nature. The signs of toxicity in animals were increased excretion of saliva, gastro-intestinal symptoms, loose stools and ion imbalance. These occurred at dosages which provided >17-fold the systemic exposure seen at the clinical dosage. In monkeys, the adverse effects appeared at doses from 150 mg/kg/day (>232-fold the systemic exposure seen at the clinical dose). In animal studies, montelukast did not affect fertility or reproductive performance at systemic exposure exceeding the clinical systemic exposure by greater than 24-fold. A slight decrease in pup body weight was noted in the female fertility study in rats at 200 mg/kg/day (>69



No deaths occurred following a single oral administration of montelukast sodium at doses up to 5000 mg/kg in mice and rats (15,000 mg/m2 and 30,000 mg/m2 in mice and rats, respectively), the maximum dose tested. This dose is equivalent to 25,000 times the recommended daily adult human dose (based on an adult patient weight of 50 kg).



Montelukast was determined not to be phototoxic in mice for UVA, UVB or visible light spectra at doses up to 500 mg/kg/day (approximately >200-fold based on systemic exposure). Montelukast was neither mutagenic in in vitro and in vivo tests nor tumorigenic in rodent species.
