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.
Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory effects via inhibition of inflammatory mediators such as cytokines and prostaglandins.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
9 mg orally once daily in the morning for up to 8 weeks.

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.
Terminal elimination half-life is approximately 2-3 hours; clinically, the extended intestinal release formulation maintains local activity despite short systemic half-life.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Primarily fecal (60-70%) with minimal renal excretion (<10%); extensively metabolized hepatically, metabolites excreted in bile and feces.
