Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis; modulates gene expression and immune cell activity.
Corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators (e.g., cytokines, chemokines, adhesion molecules) and suppression of inflammatory cell migration and activation in the airways.
Intramuscular: 40-80 mg every 2-4 weeks; Intra-articular: 5-40 mg depending on joint size; Intralesional: 2.5-25 mg; Oral: 4-12 mg/day divided every 6-12 hours.
Inhalation: 1-2 inhalations twice daily (morning and evening). Typical adult dose: 200-400 mcg twice daily. Maximum: 800 mcg/day.

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
The terminal elimination half-life of mometasone furoate following inhalation via ASMANEX TWISTHALER is approximately 5 hours (range 4–6 hours) in patients with asthma. This relatively short half-life supports twice-daily or once-daily dosing with sustained clinical effect due to prolonged local retention in the lungs.
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
Following oral inhalation, the absorbed fraction of mometasone furoate is extensively metabolized in the liver via CYP3A4. Unchanged drug and metabolites are excreted primarily in the feces via biliary elimination (approximately 74% of a single oral dose) and to a minor extent in the urine (approximately 8%). For inhaled doses, renal excretion of unchanged drug is negligible (<1% of administered dose).
