ARMONAIR DIGIHALER vs QVAR REDIHALER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ARMONAIR DIGIHALER contains fluticasone furoate and umeclidinium, and vilanterol. Fluticasone furoate is a corticosteroid that exerts anti-inflammatory effects by binding to glucocorticoid receptors, modulating gene expression to reduce inflammatory mediators. Umeclidinium is a long-acting muscarinic antagonist (LAMA) that blocks acetylcholine at M3 receptors, causing bronchodilation. Vilanterol is a long-acting beta2-adrenergic agonist (LABA) that stimulates beta2 receptors, leading to smooth muscle relaxation and bronchodilation.
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 (55 mcg each) orally twice daily for maintenance treatment of airflow obstruction in chronic obstructive pulmonary disease (COPD).
Inhalation: 40-80 mcg twice daily; maximum 320 mcg twice daily.

Terminal elimination half-life of unchanged arformoterol is approximately 26 hours (range 21-30 hours). This supports twice-daily dosing with approximately 2 days to steady state.
1.5-2.0 hours (terminal half-life) after inhalation; supports twice-daily dosing.
Renal: approximately 70% as unchanged drug; biliary/fecal: approximately 30%
Primarily hepatic metabolism via CYP3A4; metabolites are excreted in feces (~64%) and urine (~12%).
