CORTONE vs PENECORT
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.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
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.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.

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: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
