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 sodium succinate is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis; it also decreases cytokine production and immune cell activity.
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.
Intravenous (IV) or intramuscular (IM) injection: 10-40 mg initially, then 10-40 mg every 6-12 hours. For pulse therapy: 1 g IV over 30 minutes daily for 3-5 days.

Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Terminal elimination half-life: 2.5-3.5 hours (plasma); biological half-life: 12-36 hours (based on pharmacodynamic effects due to intracellular receptor binding and gene regulation)
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
Renal: ~75% as metabolites (20-30% unchanged); Biliary/Fecal: minor (<10%)
