Provair 10mg 10pcs

Indications

Provair 10 is a prescription drug indicated for the prevention of asthma attacks and relief of allergy symptoms such as runny nose and sneezing. It eases breathing by reducing airway irritation.

Pharmacology

Montelukast (CysLT1) is a selective and orally active leukotriene receptor antagonist that inhibits the cysteinyl leukotriene receptor. Cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are produced from various cells, including mast cells and eosinophils, as a result of arachidonic acid metabolism. These leukotrienes and the occupation of leukotriene receptors have been linked to the pathophysiology of asthma and allergic rhinitis, which includes airway edema, smooth muscle contraction, and altered cellular activity associated with the inflammatory process, all contributing to asthma symptoms.

Dosage & Administration

Adults and adolescents (15 years and older) should take 10mg/day for asthma and allergic rhinitis and 10mg/day for exercise-induced bronchoconstriction. 

Pediatric patients (6 to 14 years) should take 5mg/day for asthma and allergic rhinitis and 5mg/day for exercise-induced bronchoconstriction. 

Pediatric patients (6 months to 5 years) should take 4mg/day for asthma and allergic rhinitis. 

Patients with both asthma and allergic rhinitis should take only one tablet per day in the evening, at least two hours before activity to avoid acute exercise-induced bronchoconstriction.

Interaction

Montelukast can be taken with theophylline, prednisone, prednisolone, terfenadine, digoxin, warfarin, gemfibrozil, itraconazole, sedative-hypnotics, non-steroidal anti-inflammatory drugs, benzodiazepines, decongestants, oral contraceptives, and CYP enzyme inducers without changing the dose.
