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.
Fluticasone propionate is a corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, reduction of eosinophil recruitment, and suppression of airway hyperresponsiveness.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).

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.
Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
