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.
Synthetic glucocorticoid receptor agonist; modulates transcription via glucocorticoid response elements, suppressing inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and immune cell activity.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
Initial dose: 600 mg (6 tablets of 100 mg or 3 tablets of 200 mg) orally once daily for 4 weeks, then 400 mg orally once daily for weeks 5-8; total treatment duration 8 weeks.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life is approximately 2.5-3 hours in adults. The half-life may be prolonged in patients with hepatic impairment.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Primarily hepatic metabolism; <10% excreted unchanged in urine. Fecal excretion accounts for approximately 30% of metabolites. Renal excretion of metabolites accounts for about 60%.
