CORTONE vs LIQUID PRED
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 mediators (cytokines, prostaglandins, leukotrienes).
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/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

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.
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
