Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
Corticosteroid with anti-inflammatory and immunosuppressive properties; binds to glucocorticoid receptor, modulating gene expression and suppressing cytokine production, inflammation, and immune cell activity.
100 mg intravenously every 8 hours for 24 hours, then 50 mg intravenously every 8 hours for 48 hours, followed by 25 mg intravenously every 8 hours for 72 hours.
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 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
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.
Primarily renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
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.
