Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to increased transcription of anti-inflammatory proteins and suppression of pro-inflammatory mediators.
Fluticasone propionate is a synthetic trifluorinated corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as cytokines, leukotrienes, and prostaglandins. It reduces airway hyperresponsiveness and suppresses eosinophil activity.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.
100 mcg inhaled orally twice daily

3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
The terminal elimination half-life of fluticasone propionate is approximately 7.8 hours (range 5-11 hours) following inhalation. This supports twice-daily dosing, though the therapeutic effect is driven by local lung retention rather than systemic half-life.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
Fluticasone propionate is primarily eliminated via hepatic metabolism (CYP3A4) with less than 5% of a dose excreted unchanged in urine. Fecal excretion accounts for approximately 90% of the absorbed dose (as metabolites). Biliary elimination is minimal.
