DRICORT vs HYDROCORTONE
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.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
100-500 mg intravenously every 2-6 hours for initial management of adrenal insufficiency; oral maintenance: 20-30 mg daily in divided doses (e.g., 10 mg morning, 5 mg afternoon).

Terminal elimination half-life is 10-12 hours in adults with normal renal function, allowing twice-daily dosing.
Terminal elimination half-life: 1.5–2.5 hours (plasma), but biological half-life (duration of HPA axis suppression) is 8–12 hours.
Primarily renal (80-85% as unchanged drug and metabolites), with 15-20% excreted in feces via biliary elimination.
Renal (primarily as inactive metabolites; <5% unchanged) and biliary/fecal (minor).
