Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortisone is a corticosteroid that binds to glucocorticoid receptors, leading to decreased inflammation through inhibition of phospholipase A2, reduced cytokine production, and suppression of immune cell migration.
Fluticasone propionate is a corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, reduction of eosinophil recruitment, and suppression of airway hyperresponsiveness.
Oral: 25-300 mg daily in 1-4 divided doses; typical initial dose 150-300 mg daily. IM/IV: 100-500 mg every 6-12 hours.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).

Terminal half-life: 8-12 hours (cortisone) but cortisone is a prodrug; active metabolite cortisol has half-life 1.5-2 hours. Clinical context: duration of action 8-12 hours due to prolonged receptor occupancy.
Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
