ANUSOL HC vs AQNEURSA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone, a corticosteroid, binds to glucocorticoid receptors, inhibiting phospholipase A2 activity and reducing prostaglandin and leukotriene synthesis. It also suppresses cytokine production and inflammatory cell migration, leading to decreased edema, erythema, and pruritus in anorectal tissues.
AQNEURSA is a monoclonal antibody that binds to and inhibits the activity of serum amyloid A (SAA), reducing amyloid deposition in tissues.
Apply a thin layer to the affected area rectally 2 to 4 times daily, or after each bowel movement, for up to 7 days. Each application should not exceed 1 gram.
AQNEURSA (ursodiol) is administered orally at 13–15 mg/kg/day in 2–4 divided doses for primary biliary cholangitis. For gallstone dissolution, the dose is 8–10 mg/kg/day in 2–3 divided doses, with a maximum of 300 mg twice daily.

Terminal elimination half-life of hydrocortisone is approximately 1.5-2 hours (range 1-3 h) in adults; clinical effect outlasts half-life due to intracellular receptor-mediated action.
Terminal elimination half-life is 12-15 hours in patients with normal renal function; prolonged in renal impairment (up to 30-40 hours in severe cases).
Renal (primarily as metabolites) >80%; fecal ~15%; <2% unchanged in urine due to extensive hepatic metabolism. Biliary excretion is negligible.
Approximately 70-80% of the dose is excreted renally as unchanged drug; 20-30% is eliminated via biliary/fecal routes.
