ACETIC ACID W/ HYDROCORTISONE vs ARISTOCORT
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.
Glucocorticoid receptor agonist; suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis; modulates gene expression and immune cell activity.
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.
Intramuscular: 40-80 mg every 2-4 weeks; Intra-articular: 5-40 mg depending on joint size; Intralesional: 2.5-25 mg; Oral: 4-12 mg/day divided every 6-12 hours.

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.
Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
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. Biliary/fecal elimination minor.
