Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist of glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of pro-inflammatory cytokines, and suppression of immune cell activity.
Synthetic glucocorticoid with anti-inflammatory, immunosuppressive, and metabolic effects; binds to glucocorticoid receptor, modulating gene expression and inhibiting phospholipase A2, cytokine production, and immune cell activity.
Initial dose: 5-60 mg orally or intravenously once daily or divided every 12-24 hours; range 5-60 mg/day. For acute conditions, 40-60 mg once daily.
Initial adult dose 5-60 mg orally once daily, adjusted based on disease severity and response. Typically administered as a single dose in the morning with food.

Terminal elimination half-life is 2.1–3.5 hours in adults (mean 2.6 h). Clinical context: Short half-life supports twice-daily dosing for most conditions; prolonged in hepatic impairment (up to 8 h).
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal excretion of inactive metabolites (primarily prednisolone) accounts for >80% of elimination; less than 10% excreted unchanged. Biliary/fecal excretion is negligible (<5%).
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
