DRICORT vs PREDNISONE INTENSOL
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.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression to produce 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.
5-60 mg orally once daily or divided twice daily, titrated to response.

Terminal elimination half-life is 10-12 hours in adults with normal renal function, allowing twice-daily dosing.
2-4 hours (terminal) for prednisone; prednisolone half-life 2-4 hours. Clinical context: shorter than anti-inflammatory effect due to delayed receptor-mediated action.
Primarily renal (80-85% as unchanged drug and metabolites), with 15-20% excreted in feces via biliary elimination.
Renal: <30% unchanged; major metabolites (prednisolone, 20-dihydroprednisolone) conjugated and excreted in urine. Fecal: <10%.
