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 glucocorticoid receptor agonist. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, chemokines, and adhesion molecules. It also 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/day orally or intramuscularly in divided doses every 12 hours; for acute conditions, up to 120 mg/day intravenously in divided doses every 4-6 hours.

Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Terminal elimination half-life: 2–4 hours. Clinical context: shorter than other corticosteroids; requires multiple daily doses for sustained anti-inflammatory effect.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
Primarily hepatic metabolism; <20% excreted unchanged in urine. Negligible biliary/fecal elimination.
