CORTONE vs DEXACEN-4
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.
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.
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.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.

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.
3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
