BECLOVENT vs QVAR 80
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 corticosteroid that exhibits anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as cytokines, chemokines, and arachidonic acid metabolites. It also reduces edema and mucus production in the airways.
2 inhalations (84 mcg) twice daily; not to exceed 10 inhalations (420 mcg) per day. Administered via oral inhalation using a metered-dose inhaler.
80 mcg orally via oral inhalation 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.
Terminal elimination half-life is approximately 2.9 hours after inhalation. This short half-life supports twice-daily dosing but does not fully reflect pulmonary residence time.
Primarily hepatic metabolism via CYP3A4; metabolites are excreted in feces (60-70%) and urine (10-15%); less than 5% unchanged drug in urine.
