ACETIC ACID W/ HYDROCORTISONE vs HYDROCORTONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
100-500 mg intravenously every 2-6 hours for initial management of adrenal insufficiency; oral maintenance: 20-30 mg daily in divided doses (e.g., 10 mg morning, 5 mg afternoon).

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.
Terminal elimination half-life: 1.5–2.5 hours (plasma), but biological half-life (duration of HPA axis suppression) is 8–12 hours.
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.
Renal (primarily as inactive metabolites; <5% unchanged) and biliary/fecal (minor).
