ACETIC ACID W/ HYDROCORTISONE vs BETAPAR
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.
Beta-2 adrenergic receptor agonist that stimulates adenylyl cyclase, increasing cAMP levels, leading to bronchodilation.
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.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.

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 is 3-5 hours in patients with normal renal function; prolonged to 10-20 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 excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; the remainder undergoes hepatic metabolism.
