Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic glucocorticoid receptor agonist; modulates transcription via glucocorticoid response elements, suppressing inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and immune cell activity.
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.
Initial dose: 600 mg (6 tablets of 100 mg or 3 tablets of 200 mg) orally once daily for 4 weeks, then 400 mg orally once daily for weeks 5-8; total treatment duration 8 weeks.
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.

Terminal elimination half-life is approximately 2.5-3 hours in adults. The half-life may be prolonged in patients with hepatic impairment.
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
Primarily hepatic metabolism; <10% excreted unchanged in urine. Fecal excretion accounts for approximately 30% of metabolites. Renal excretion of metabolites accounts for about 60%.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
