ARISTOCORT vs TRIACORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis; modulates gene expression and immune cell activity.
Adrenocorticosteroid; binds to glucocorticoid receptor, modulating gene expression to produce anti-inflammatory, immunosuppressive, and metabolic effects.
Intramuscular: 40-80 mg every 2-4 weeks; Intra-articular: 5-40 mg depending on joint size; Intralesional: 2.5-25 mg; Oral: 4-12 mg/day divided every 6-12 hours.
10-20 mg orally once daily

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
2-3 h. The terminal elimination half-life is short, requiring thrice-daily dosing for sustained effect. Context: In patients with hepatic impairment, half-life may be prolonged up to 4-5 h.
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
Primarily hepatic metabolism (>90%) with renal excretion of inactive metabolites (approximately 80% in urine, 20% in feces). Less than 5% of the parent drug is excreted unchanged in urine.
