DRICORT vs PENECORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with predominant glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression and suppressing inflammatory mediators (e.g., prostaglandins, leukotrienes) and immune cell function.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
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.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.

Terminal elimination half-life is 10-12 hours in adults with normal renal function, allowing twice-daily dosing.
Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Primarily renal (80-85% as unchanged drug and metabolites), with 15-20% excreted in feces via biliary elimination.
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
