NEOMYCIN SULFATE-TRIAMCINOLONE ACETONIDE vs TEXACORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
TEXACORT (hydrocortisone) is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, immunosuppressive, and metabolic effects.
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.
50 mg intravenously every 6 hours as a single agent or in combination with other antineoplastic agents.

Neomycin: 2-3 hours (normal renal function); in renal impairment, prolonged up to 12-24 hours. Triamcinolone acetonide: 2-5 hours (terminal).
Terminal elimination half-life: 3-4 hours. In renal impairment, half-life may be prolonged up to 12 hours.
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%.
Renal: 80-90% as unchanged drug and inactive metabolites; biliary/fecal: 10-20%.
