CORTONE vs ORAPRED
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.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, 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.
5-60 mg orally once daily or divided as 5-15 mg every 4-12 hours; adjust based on response and 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.
4-5 hours (terminal); prolonged in renal impairment (up to 12+ hours in anuria) and hepatic dysfunction; clinical context: dosing interval adjustment in severe renal failure
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Renal: approximately 60-80% as unchanged drug and conjugated metabolites; biliary/fecal: minor (5-10%)
