DEXACORT vs ENTOCORT EC
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.
Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory effects via inhibition of inflammatory mediators such as cytokines and prostaglandins.
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.
9 mg orally once daily in the morning for up to 8 weeks.

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 is approximately 2-3 hours; clinically, the extended intestinal release formulation maintains local activity despite short systemic half-life.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Primarily fecal (60-70%) with minimal renal excretion (<10%); extensively metabolized hepatically, metabolites excreted in bile and feces.
