Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene transcription. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis; suppresses inflammatory cytokine production; and causes vasoconstriction and immunosuppression.
Triamcinolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
Hydrocortisone 100-500 mg IV/IM every 2-6 hours as needed for acute adrenal insufficiency or severe inflammation. Maintenance: 20-30 mg/day PO divided every 8-12 hours.
50 mg orally once daily.

1.5–2.5 hours (terminal half-life). In clinical context, the biological half-life (duration of HPA suppression) is longer (8–12 hours) due to tissue binding and active metabolites.
Terminal elimination half-life is 12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in severe hepatic impairment.
Renal: predominantly as conjugated metabolites and a small fraction of unchanged drug. Biliary/fecal: minor, <5%. Total renal clearance accounts for >95% of elimination.
Renal excretion of unchanged drug accounts for 70% of elimination; biliary/fecal elimination accounts for 20%; 10% metabolized to inactive metabolites.
