CORTONE vs HYDROCORTISONE AND ACETIC ACID
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.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to increased lipocortin synthesis, inhibition of phospholipase A2, decreased arachidonic acid release, and reduced prostaglandin and leukotriene production; it also suppresses cytokine expression and immune cell migration. Acetic acid is a weak acid that lowers local pH, inhibiting bacterial and fungal growth and disrupting microbial cell membranes.
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.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.

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.
Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
