Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.
1.5 mg orally 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 half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
