BECLOVENT vs QVAR REDIHALER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; inhibits inflammatory mediators, reduces airway hyperresponsiveness, and suppresses immune cell activity.
Beclomethasone dipropionate is a prodrug that is hydrolyzed by esterases to the active metabolite beclomethasone-17-monopropionate (17-BMP). 17-BMP is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to modulation of gene expression involved in inflammatory pathways, including inhibition of pro-inflammatory cytokines, reduction of eosinophil survival and migration, and suppression of mast cell mediators.
2 inhalations (84 mcg) twice daily; not to exceed 10 inhalations (420 mcg) per day. Administered via oral inhalation using a metered-dose inhaler.
Inhalation: 40-80 mcg twice daily; maximum 320 mcg twice daily.

Terminal elimination half-life of beclomethasone dipropionate is 0.5 hours; active metabolite beclomethasone-17-monopropionate has half-life of 2.7 hours; clinically, systemic effects persist for 12-24 hours.
1.5-2.0 hours (terminal half-life) after inhalation; supports twice-daily dosing.
Primarily hepatic metabolism via CYP3A4; metabolites are excreted in feces (60-70%) and urine (10-15%); less than 5% unchanged drug in urine.
