A-METHAPRED vs PREDNISONE INTENSOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines, prostaglandins, and leukotrienes. It also induces lipocortin synthesis, inhibits phospholipase A2, and reduces immune cell activity.
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.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
5-60 mg orally once daily or divided twice daily, titrated to response.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
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.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Renal: <30% unchanged; major metabolites (prednisolone, 20-dihydroprednisolone) conjugated and excreted in urine. Fecal: <10%.
