ACETIC ACID W/ HYDROCORTISONE vs METICORTELONE
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.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
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.
Prednisolone: 5-60 mg orally once daily or divided twice daily; methylprednisolone: 4-48 mg orally once daily or divided twice daily. Dose and duration vary by indication.

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: 3.0-3.5 hours; clinical context: requires multiple daily doses for sustained effect; biological half-life (duration of HPA suppression) longer (~24-36 hours) due to intracellular activity
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: <5% unchanged; hepatic metabolism to inactive metabolites, primarily conjugated and excreted in urine; <2% fecal
