Overview
11 DESCRIPTION The active component of QVAR REDIHALER 40 mcg Inhalation Aerosol and QVAR REDIHALER 80 mcg Inhalation Aerosol is beclomethasone dipropionate, USP, a corticosteroid having the chemical name 9-chloro-11ß,17,21-trihydroxy-16ß-methylpregna-1,4-diene-3,20-dione 17,21-dipropionate.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Beclomethasone dipropionate is a corticosteroid demonstrating potent anti‑inflammatory activity. The precise mechanism of corticosteroid action on asthma is not known. Corticosteroids have been shown to have multiple anti‑inflammatory effects, inhibiting both inflammatory cells (e.g., mast cells, eosinophils, basophils, lymphocytes, macrophages, and neutrophils) and release of inflammatory mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines). These anti‑inflammatory actions of corticosteroids contribute to their efficacy in asthma. Beclomethasone dipropionate is a prodrug that is rapidly activated by hydrolysis to the active monoester, 17‑monopropionate (17‑BMP).
