Reduction in Concomitant Therapy: Bronchodilator Treatments: OPIKAST can be added to the treatment regimen of patients who are not adequately controlled on bronchodilator alone. When a clinical response is evident (usually after the first dose), the patient's bronchodilator therapy can be reduced as tolerated. Inhaled Corticosteroids: Treatment with OPIKAST provides additional clinical benefit to patients treated with inhaled corticosteroids. A reduction in the corticosteroid dose can be made as tolerated. The dose should be reduced gradually with medical supervision. In some patients, the dose of Inhaled corticosteroids can be tapered off completely, OPIKAST should not be abruptly substituted for inhaled corticosteroids.

NURSING MOTHERS

It is not known if OPIKAST is excreted in human milk . Because many drugs are excreted in human milk, caution should be exercised when OPIKAST is given to a nursing mother.

PEDIATRIC USE

montelukast has been studied in pediatric patients 6 months to 14 years of age (see Dosage and Administration). Safety and effectiveness in pediatric patients younger than 6 months of age have not been studied. Studies have shown that montelukast does not affect the growth rate of pediatric patients.

USE IN THE ELDERLY

In clinical studies. there were no age-related differences in the efficacy or safety profiles of montelukast sodium.

DRUG INTERACTIONS

OPIKAST may be administered with other therapies routinely used in the prophylaxis and chronic treatment of asthma. and in the treatment of allergic rhinitis. In drug-interactions studies. the recommended clinical dose of montelukast did not have clinically important effects on the pharmacokinetics of the following drugs: theophylline. prednisone. prednisolone, oral contraceptives (ethinyl estradior/norethindrone 35/1), terfenadine, digoxin and warfarin.   The area under the plasma concentration-time curve (AUC) for montelukast was decreased approximately 40% in subjects with co-administration of phenobarbital. No dosage adjustment for montelukast is recommended. In vitro studies have shown that montelukast is an inhibitor of CYP 2C8. Montelukast may inhibit the metabolism of drugs primarily metabolized by CYP 2CB. (E.g., paclitaxel. rosiglitazone. repaglinide);however. no in vivo interaction studies have been performed.
