Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Suppresses cytokine production, inhibits phospholipase A2, and reduces prostaglandin and leukotriene synthesis.
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.
0.1-0.2 mg/kg intravenously once.
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 2-4 hours. Clinical context: Short half-life requires frequent dosing for sustained effect; accumulation possible in renal impairment.
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal excretion of unchanged drug and metabolites accounts for approximately 70-80% of elimination, with biliary/fecal excretion contributing 20-30%.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
