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.
Long-acting muscarinic antagonist (LAMA); inhibits acetylcholine at M3 receptors in bronchial smooth muscle, causing bronchodilation.
Two inhalations (umeclidinium 62.5 mcg and vilanterol 25 mcg per inhalation) orally once daily.
1 inhalation (27.5 mcg glycopyrrolate/12.5 mcg formoterol fumarate) twice daily via oral inhalation.

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: 22 hours (range 16–33 h) in patients with COPD; supports once-daily dosing.
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.
Primarily fecal (58% of radiolabeled dose) and renal (22%) after intravenous administration, with unchanged drug as minor component. Biliary excretion accounts for fecal elimination.
