Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
Corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating cytokine production.
0.5-9 mg/day orally in divided doses every 6-12 hours; intravenously or intramuscularly as dexamethasone sodium phosphate; typical anti-inflammatory dose 0.75-9 mg/day. For cerebral edema: IV loading dose 10 mg, then 4 mg every 6 hours. For COVID-19: 6 mg IV or orally once daily for up to 10 days.
1 to 4 mg (0.025 to 0.1 mL of 40 mg/mL suspension) intravitreal injection once.

Terminal elimination half-life: 3-5 hours in adults; slightly prolonged in neonates (approximately 12-24 hours) and patients with hepatic impairment. Clinical context: Duration of HPA axis suppression may exceed the presence of measurable drug; single dose typically suppresses cortisol for 24-36 hours.
Approximately 3.3 hours for triamcinolone acetonide; with intravitreal administration, detectable levels persist for weeks to months.
Renal (primarily as glucuronide and sulfate conjugates) and biliary/fecal (minor). Approximately 65-80% of a dose is excreted in urine within 24 hours as 20-beta-dihydrodexamethasone (inactive) and conjugated metabolites; about 10-15% appears in feces. Less than 5% is excreted unchanged.
Primarily hepatic metabolism; renal excretion of metabolites (<5% unchanged). Biliary/fecal elimination accounts for minimal clearance.
