ARISTOCORT vs DRICORT
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.
Corticosteroid with predominant glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression and suppressing inflammatory mediators (e.g., prostaglandins, leukotrienes) and immune cell function.
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.
DRICORT (dexamethasone) typical adult dose: 0.5-9 mg/day orally in divided doses every 6-12 hours, or 0.5-24 mg IV/IM once or divided. Anti-inflammatory: 0.75-9 mg/day PO/IV in 2-4 divided doses. Severe conditions: up to 16 mg/day in divided doses. Short-term high-dose: up to 40-100 mg IV push for specific indications.

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
Terminal elimination half-life is 10-12 hours in adults with normal renal function, allowing twice-daily dosing.
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
Primarily renal (80-85% as unchanged drug and metabolites), with 15-20% excreted in feces via biliary elimination.
