Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a corticosteroid hormone that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, inhibit immune response, and regulate metabolism.
Acetic acid exerts antibacterial and antifungal activity by lowering pH and disrupting microbial cell membranes. Hydrocortisone is a corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties.
Adrenal insufficiency: oral 20-30 mg/day in divided doses; inflammatory conditions: 5-60 mg/day oral; IV/IM: hydrocortisone sodium succinate 50-100 mg every 4-6 hours.
1 applicatorful (approximately 5 g) of the cream or ointment (containing 2% acetic acid and 1% hydrocortisone) inserted intravaginally once or twice daily for 7 days.

Terminal half-life: 1.5-2 hours (cortisol); clinical effect persists 8-12 hours due to glucocorticoid receptor binding
Acetic acid: not applicable; hydrocortisone: plasma half-life ~1.5 hours (biologic half-life 8–12 hours). Due to low systemic absorption from topical application, systemic half-life is clinically irrelevant.
Renal (primarily as metabolites, <1% unchanged); biliary/fecal (<5%)
Acetic acid: minimal systemic absorption; hydrocortisone: hepatic metabolism, renal excretion of metabolites (<5% unchanged). Less than 10% of applied dose excreted in urine as metabolites; biliary/fecal excretion negligible.
