Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Corticosteroid with anti-inflammatory and immunosuppressive properties; binds to glucocorticoid receptor, modulating gene expression and suppressing cytokine production, inflammation, and immune cell activity.
2 inhalations (100 mcg each) twice daily orally, maximum 400 mcg/day.
40 to 80 mg intramuscularly every 4 weeks; intra-articular: 5 to 40 mg per joint every 3-4 weeks; intralesional: up to 1 mg per injection site, not to exceed 0.1 mg per cm² of lesion.

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.
The terminal elimination half-life is approximately 2-5 hours in adults. This relatively short half-life supports multiple daily dosing for chronic conditions, though the biological half-life (duration of adrenal suppression) is longer at 18-36 hours due to intracellular receptor binding.
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.
Triamcinolone diacetate is metabolized primarily in the liver and excreted via the kidneys as inactive metabolites. Approximately 30-40% of an oral dose is excreted in urine as metabolites, with less than 5% as unchanged drug. Biliary/fecal excretion accounts for about 60-70% of the administered dose.
