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.
Glucocorticoid receptor agonist; anti-inflammatory transcription factor modulation; inhibits phospholipase A2, reduces arachidonic acid release, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and inflammatory cell migration.
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.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.

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.
Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
