Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to regulation of gene expression and suppression of inflammatory cytokines, 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.
Adult: 0.75-9 mg/day orally in divided doses every 6-12 hours; IV/IM: initial 0.5-9 mg/day in divided doses every 6-12 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: 36-54 hours; prolonged in hepatic impairment (up to 72 hours) due to reduced clearance.
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: ~65-80% as unchanged drug and metabolites via glomerular filtration, with tubular reabsorption; minor biliary/fecal (5-10%).
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.
