Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, suppress cytokine production, and decrease inflammation and immune responses.
Mometasone furoate is a corticosteroid that exerts anti-inflammatory effects by inhibiting multiple inflammatory cell types and mediators, including eosinophils, mast cells, macrophages, and lymphocytes, and reducing the release of pro-inflammatory cytokines and chemokines.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
2 inhalations (100 mcg each) twice daily orally, maximum 400 mcg/day.

Terminal half-life: 2-3 hours for triamcinolone acetonide. Clinical context: Duration of action longer due to receptor binding and intracellular activity; anti-inflammatory effects persist 24-48 hours after IM administration.
The terminal elimination half-life of mometasone furoate following inhalation is approximately 25 hours (range 15–40 hours), reflecting slow absorption from the lungs and prolonged systemic clearance.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Following oral inhalation, the absorbed fraction of mometasone furoate is extensively metabolized in the liver. Excretion is primarily via feces (approximately 74%) and urine (approximately 8%) as metabolites. Biliary excretion contributes to fecal elimination.
