ACETIC ACID W/ HYDROCORTISONE vs TARPEYO
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.
TARPEYO (budesonide) is a corticosteroid with anti-inflammatory activity. It acts by binding to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines and immune cell activation, thereby reducing proteinuria in IgA nephropathy.
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.
16 mg/kg intravenously once daily on Days 1-5 of each 28-day cycle.

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 approximately 27.3 hours (range 21-36 hours) in patients with IgA nephropathy. This supports once-weekly subcutaneous dosing without dose adjustment over the dosing interval.
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, with <1% excreted unchanged in urine and <1% in feces. Elimination is predominantly via biliary excretion of metabolites into feces, accounting for >90% of total clearance.
