ACETIC ACID W/ HYDROCORTISONE vs TRIESENCE
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 that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating 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.
1 to 4 mg (0.025 to 0.1 mL of 40 mg/mL suspension) intravitreal injection once.

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.
Approximately 3.3 hours for triamcinolone acetonide; with intravitreal administration, detectable levels persist for weeks to months.
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.
Primarily hepatic metabolism; renal excretion of metabolites (<5% unchanged). Biliary/fecal elimination accounts for minimal clearance.
