Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses inflammatory cytokines and immune cell activity.
Corticosteroid with anti-inflammatory and immunosuppressive properties; binds to glucocorticoid receptor, modulating gene expression and suppressing cytokine production, inflammation, and immune cell activity.
IV or IM: 10-40 mg methylprednisolone (as sodium succinate) every 4-6 hours; high-dose pulse therapy: 30 mg/kg IV over 30-60 minutes every 4-6 hours for 48-72 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: 2.5–3.5 hours. In clinical context, the biologic half-life (suppression of HPA axis) is longer (24–36 hours) due to tissue retention of active metabolites.
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: approximately 80% as metabolites (glucuronide and sulfate conjugates) and unchanged drug; biliary/fecal: less than 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.
