DEXACORT vs DEXASPORIN
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.
Dexasporin is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of pro-inflammatory mediators such as prostaglandins and leukotrienes.
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.
1 to 2 mg/kg intramuscular or intravenous every 8 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
3-4 hours (prolonged to 10-15 hours in renal impairment; monitor CrCl <30 mL/min)
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal excretion (80-90% unchanged), biliary/fecal (10-20%)
