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.
Triamcinolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
50 mg orally once daily.

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.
Terminal elimination half-life is 12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in severe hepatic impairment.
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.
Renal excretion of unchanged drug accounts for 70% of elimination; biliary/fecal elimination accounts for 20%; 10% metabolized to inactive metabolites.
