Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a synthetic corticosteroid with potent anti-inflammatory, immunosuppressive, and anti-proliferative effects. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of phospholipase A2, which reduces prostaglandin and leukotriene synthesis. It also suppresses cytokine production and immune cell migration.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
60 mg (1.5 mL) intramuscularly (deep IM) as a single dose for allergic/ inflammatory conditions; intra-articular or soft tissue injection: 10-40 mg for large joints, 5-25 mg for medium joints, 2.5-10 mg for small joints; intralesional: up to 1 mg per injection site, repeated as needed.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.

Terminal elimination half-life: 2–4 hours for triamcinolone acetonide; prolonged in hepatic impairment (up to 6–8 hours).
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.
Primarily hepatic metabolism followed by renal excretion of inactive metabolites; less than 5% excreted unchanged in urine, with minor biliary/fecal elimination (<2%).
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.
