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.
Fluocinonide acetonide is a corticosteroid that binds to glucocorticoid receptors, modulating gene transcription to induce anti-inflammatory, antipruritic, and vasoconstrictive effects. It inhibits phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis.
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.
Apply a thin film to affected area 1 to 3 times daily, depending on severity. Maximum: 2 weeks continuous use. Not for use on face, groin, or axillae. Dispense 15-60 g per application.

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 approximately 48-72 hours; prolonged in hepatic impairment due to reduced clearance; duration of action at skin sites persists up to 4-6 hours post-application.
Renal (primarily as metabolites) >80%; fecal ~15%; <2% unchanged in urine due to extensive hepatic metabolism. Biliary excretion is negligible.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <1% unchanged drug in urine; biliary/fecal excretion accounts for ~60% of metabolites.
