BREO ELLIPTA vs DEFLAZACORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of fluticasone furoate, a corticosteroid that binds to glucocorticoid receptors to inhibit inflammatory gene transcription, and vilanterol, a long-acting beta2-adrenergic agonist that activates adenylate cyclase leading to bronchodilation.
Deflazacort is a glucocorticoid prodrug that is metabolized to its active form, 21-desacetyldeflazacort. It binds to glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating cytokine production.
One inhalation (100 mcg fluticasone furoate / 25 mcg vilanterol) once daily via oral inhalation.
6-90 mg orally once daily; initial dose typically 6-30 mg/day, maintenance as lowest effective dose; taper gradually upon discontinuation.

Fluticasone furoate: 24 hours (supports once-daily dosing). Vilanterol: 11 hours (supports once-daily dosing).
Terminal half-life of the active metabolite Δ6-deflazacort is 1.1–1.9 hours; parent drug half-life is approximately 1–2 hours. Clinical glucocorticoid effect persists for 12–24 hours due to receptor binding.
Fluticasone furoate is eliminated primarily via fecal excretion (approximately 101% of an oral dose) due to biliary clearance, with minimal renal excretion (<1%). Vilanterol is eliminated via metabolism and subsequent renal (approximately 70% of an IV dose) and fecal (approximately 30% of an IV dose) excretion.
Renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal (approximately 30%)
