DEXACORT vs UCERIS
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.
Uceris (budesonide) is a corticosteroid with potent glucocorticoid activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines (e.g., IL-1, IL-2, IL-4, IL-5, TNF-alpha), suppression of arachidonic acid metabolism via phospholipase A2 inhibition, and reduction of inflammatory cell infiltration. It has high topical anti-inflammatory activity and undergoes extensive first-pass hepatic metabolism, minimizing systemic bioavailability.
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.
For induction of remission in mild to moderate active ulcerative colitis: one 9 mg extended-release tablet orally once daily 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
2.8-4.5 hours (terminal). Clinical context: short half-life supports once-daily extended-release formulation for colonic delivery.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal: <1%. Fecal: approximately 63% as budesonide and metabolites. Biliary: minor.
