Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Suppresses cytokine production, inhibits phospholipase A2, and reduces prostaglandin and leukotriene synthesis.
Corticosteroid with anti-inflammatory and immunosuppressive properties; binds to glucocorticoid receptor, modulating gene expression and suppressing cytokine production, inflammation, and immune cell activity.
0.1-0.2 mg/kg intravenously once.
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.

Terminal elimination half-life is 2-4 hours. Clinical context: Short half-life requires frequent dosing for sustained effect; accumulation possible in renal impairment.
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.
Renal excretion of unchanged drug and metabolites accounts for approximately 70-80% of elimination, with biliary/fecal excretion contributing 20-30%.
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.
