Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to increased transcription of anti-inflammatory proteins and suppression of pro-inflammatory mediators.
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.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.
1.5 mg orally once daily

3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
