ARMONAIR RESPICLICK vs AZELASTINE HYDROCHLORIDE AND FLUTICASONE PROPIONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Armonair Respiclick is a metered-dose inhaler containing beclomethasone dipropionate, a corticosteroid. It exerts anti-inflammatory effects by binding to glucocorticoid receptors, inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing inflammatory cell migration and cytokine release in the airways.
Azelastine is a histamine H1-receptor antagonist that inhibits histamine release from mast cells; fluticasone propionate is a corticosteroid that suppresses inflammatory mediators including cytokines, prostaglandins, and leukotrienes, reducing nasal inflammation.
Inhaled: 55 mcg to 113 mcg per actuation, 1 to 2 actuations twice daily. Maximum 2 actuations twice daily.
1 spray per nostril twice daily (137 mcg azelastine hydrochloride and 50 mcg fluticasone propionate per spray).

Terminal elimination half-life is approximately 26 hours (range 21-36 hours). This supports once-daily dosing for bronchodilation in COPD.
Azelastine: ~25 hours (range 22-27 h). Fluticasone propionate: ~7.8 hours intranasal; 7-8 hours IV; context: intranasal dosing achieves steady-state in 1-2 weeks.
Renal: approximately 99% of an administered dose is excreted in urine, with 95% as conjugated metabolites and 2% as free arformoterol. Fecal: approximately 1%. Biliary: negligible.
Azelastine: 75% renal (as unchanged drug and metabolites), 25% fecal. Fluticasone propionate: primarily fecal after IV (90%), renal <5%; after intranasal, significant first-pass hepatic metabolism to inactive metabolites excreted in bile and feces.
