Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines (e.g., IL-1, IL-2, TNF-alpha). It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.
4 to 48 mg orally once daily or every other day, depending on condition. Initial dose may be up to 48 mg/day.

2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Terminal half-life of methylprednisolone is 2.5-3.5 hours; for the active metabolite (prednisolone), half-life is 2.1-3.5 hours. Clinical context: Despite short half-life, pharmacodynamic effects persist beyond plasma presence due to receptor-mediated actions.
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
Renal (approximately 80-90% as metabolites, <5% unchanged); biliary/fecal (minor, <5%)
