Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
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.
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.
4 to 48 mg orally once daily or every other day, depending on condition. Initial dose may be up to 48 mg/day.

Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
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 (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
Renal (approximately 80-90% as metabolites, <5% unchanged); biliary/fecal (minor, <5%)
