Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
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.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
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.

The terminal elimination half-life of mometasone furoate is approximately 5.8 hours. This short half-life supports once-daily dosing for intranasal use, but systemic accumulation is minimal with topical administration.
Neomycin: 2-3 hours (normal renal function); in renal impairment, prolonged up to 12-24 hours. Triamcinolone acetonide: 2-5 hours (terminal).
Mometasone furoate is predominantly eliminated via biliary/fecal excretion. After intravenous administration, approximately 74% of the dose is recovered in feces and about 8% in urine. The drug undergoes extensive hepatic metabolism, and metabolites are excreted primarily in bile.
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%.
