Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide, a corticosteroid, exerts anti-inflammatory effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production, thereby decreasing nasal inflammation.
Beclomethasone dipropionate is a corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. It binds to glucocorticoid receptors, leading to inhibition of inflammatory mediators such as cytokines and prostaglandins.
110 mcg (2 sprays) per nostril once daily; maximum: 440 mcg (4 sprays) per nostril once daily. Intranasal administration.
1-2 inhalations (50-100 mcg) per nostril twice daily (100-200 mcg/day total).

Terminal elimination half-life is approximately 3-4 hours after intranasal administration; however, due to prolonged residence time in nasal mucosa, clinical effects persist beyond plasma half-life.
Terminal elimination half-life is approximately 3.5 hours after intranasal administration. Clinically, this short half-life supports twice-daily dosing for sustained effect.
Primarily hepatic metabolism via CYP3A4; renal excretion accounts for <5% of unchanged drug; biliary/fecal excretion of metabolites accounts for ~60% of total clearance.
Primarily hepatic metabolism; excreted in urine (approximately 10% as unchanged drug and metabolites) and feces (approximately 80% as metabolites).
