Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Unknown; possibly enhances cognitive function by modulating cholinergic and dopaminergic pathways.
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.
500 mg orally every 8 hours; for severe infections, 750 mg every 12 hours or 1 g every 8 hours.
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.

3-5 hours in healthy adults; prolonged to 8-12 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 20 hours in severe impairment (CrCl <30 mL/min).
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
Renal: 60-70% unchanged; biliary/fecal: 20-30% as metabolites; total: >90% eliminated within 48 hours.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
