Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to regulation of gene expression and suppression of inflammatory cytokines, immune response, and adrenal function.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.
Adult: 0.75-9 mg/day orally in divided doses every 6-12 hours; IV/IM: initial 0.5-9 mg/day in divided doses every 6-12 hours.

Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
Terminal elimination half-life: 36-54 hours; prolonged in hepatic impairment (up to 72 hours) due to reduced clearance.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Primarily renal: ~65-80% as unchanged drug and metabolites via glomerular filtration, with tubular reabsorption; minor biliary/fecal (5-10%).
