AIRDUO DIGIHALER vs ARMONAIR RESPICLICK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Salmeterol is a long-acting beta2-adrenergic agonist (LABA) that relaxes bronchial smooth muscle by increasing cyclic AMP. Fluticasone propionate is a corticosteroid with anti-inflammatory activity that inhibits inflammatory mediators and cells.
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.
Two inhalations (umeclidinium 62.5 mcg and vilanterol 25 mcg per inhalation) orally once daily.
Inhaled: 55 mcg to 113 mcg per actuation, 1 to 2 actuations twice daily. Maximum 2 actuations twice daily.

Fluticasone furoate: terminal elimination half-life is approximately 24 hours. Vilanterol: terminal elimination half-life is approximately 11 hours. The long half-life of fluticasone furoate supports once-daily dosing, while vilanterol's half-life allows for sustained bronchodilation over 24 hours.
Terminal elimination half-life is approximately 26 hours (range 21-36 hours). This supports once-daily dosing for bronchodilation in COPD.
Fluticasone furoate and vilanterol are primarily eliminated via biliary/fecal routes. For fluticasone furoate, approximately 90% of an oral dose is excreted in feces as parent drug and metabolites, with <1% in urine. Vilanterol is predominantly excreted via feces (∼70%) as metabolites, with ∼20% in urine.
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.
