AIRDUO RESPICLICK vs QVAR REDIHALER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of fluticasone propionate (corticosteroid) and salmeterol (long-acting beta2-adrenergic agonist); fluticasone reduces inflammation via glucocorticoid receptor activation, salmeterol relaxes bronchial smooth muscle via beta2-receptor stimulation.
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.
Two inhalations (55 mcg/113 mcg per inhalation) twice daily via oral inhalation; maximum 2 inhalations twice daily. For patients with asthma, starting dose is one inhalation twice daily; may increase to two inhalations twice daily after 1-2 weeks if inadequate response.
Inhalation: 40-80 mcg twice daily; maximum 320 mcg twice daily.

Salmeterol: terminal elimination half-life of 5.5 hours. Fluticasone furoate: terminal elimination half-life of approximately 24 hours, supporting once-daily dosing.
1.5-2.0 hours (terminal half-life) after inhalation; supports twice-daily dosing.
Renal elimination of salmeterol: approximately 25% of dose excreted unchanged in urine. Fluticasone furoate: primarily excreted as metabolites in feces (≥90%) following intravenous administration, with less than 5% excreted in urine.
Primarily hepatic metabolism via CYP3A4; metabolites are excreted in feces (~64%) and urine (~12%).
