Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
The combination product contains a corticosteroid (dexamethasone) which suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and a topical antibiotic (usually neomycin or polymyxin B) which inhibits bacterial protein synthesis or disrupts bacterial cell membranes.
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.
2 puffs (100 mcg each) intranasally twice daily
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.

Terminal elimination half-life is 12-15 hours in adults with normal renal function; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
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.
Renal elimination of unchanged drug accounts for 30-40% of the dose; fecal/biliary elimination is 50-60% as metabolites. Less than 10% is excreted unchanged in feces.
Renal (primarily as metabolites) >80%; fecal ~15%; <2% unchanged in urine due to extensive hepatic metabolism. Biliary excretion is negligible.
