Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
Neomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis. Triamcinolone acetonide is a corticosteroid that induces phospholipase A2 inhibitory proteins, thereby decreasing prostaglandin and leukotriene synthesis, and exerts anti-inflammatory, antipruritic, and vasoconstrictive effects.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
Topical: Apply thin film to affected area 2-4 times daily. Otic: Instill 3-4 drops into ear canal 2-3 times daily. Not for systemic use.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Neomycin: 2-3 hours (normal renal function); in renal impairment, prolonged up to 12-24 hours. Triamcinolone acetonide: 2-5 hours (terminal).
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Neomycin: >90% orally administered excreted unchanged in feces; absorbed fraction (3-6%) excreted renally with 50% within 24 hours. Triamcinolone acetonide: primarily hepatic metabolism, renal excretion of metabolites (~40% as 11-keto derivatives), fecal excretion ~20%.
