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.
Corticosteroid with high glucocorticoid receptor affinity; reduces inflammation by inhibiting phospholipase A2, decreasing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
0.5% ophthalmic suspension: 1-2 drops into affected eye(s) four times daily. In severe cases, may be increased to 1-2 drops every hour during the first week, then taper.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life is 2.2-4.3 hours; clinical context: supports twice-daily dosing in ophthalmic use, with minimal systemic accumulation.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Primarily hepatic metabolism; metabolites excreted in urine (approximately 80% as inactive metabolites) and feces (15-20%). Less than 1% excreted unchanged in urine.
