ACETIC ACID W/ HYDROCORTISONE vs STATROL
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.
Statrol is a combination antibiotic ointment containing polymyxin B sulfate, neomycin sulfate, and gramicidin. Polymyxin B binds to lipopolysaccharides in the outer membrane of gram-negative bacteria, disrupting membrane integrity. Neomycin inhibits protein synthesis by binding to the 30S ribosomal subunit. Gramicidin alters cell membrane permeability in gram-positive bacteria by forming ion channels.
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.

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 half-life 12-16 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
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: 70% unchanged; biliary/fecal: 20% as metabolites, 10% unchanged.
