Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of prostaglandins and leukotrienes, and modulation of gene transcription.
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.
0.75-9 mg/day orally in divided doses every 6-12 hours; for anti-inflammatory/immunosuppressive effects, initial dose 0.75-9 mg/day; for cerebral edema, 10 mg IV then 4 mg IM/IV every 6 hours.
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: 36-54 hours (adults); clinically, biological half-life (duration of HPA axis suppression) is longer (24-72 hours).
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal (approximately 65-80% as metabolites, <10% as unchanged drug); biliary/fecal (minor).
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
