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.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and subsequent anti-inflammatory and immunosuppressive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses cytokine production.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
10-60 mg orally once daily or divided twice daily; maximum 60 mg/day.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life: 2-3 hours (after IV/IM/oral). Clinically, anti-inflammatory effects persist beyond plasma half-life due to glucocorticoid receptor-mediated gene transcription effects.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Primarily renal (80-90% as inactive glucuronide and sulfate conjugates; less than 10% as unchanged drug). Biliary/fecal excretion accounts for about 5%.
