DEFLAZACORT vs UCERIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Deflazacort is a glucocorticoid prodrug that is metabolized to its active form, 21-desacetyldeflazacort. It binds to glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating 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.
6-90 mg orally once daily; initial dose typically 6-30 mg/day, maintenance as lowest effective dose; taper gradually upon discontinuation.
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.

Terminal half-life of the active metabolite Δ6-deflazacort is 1.1–1.9 hours; parent drug half-life is approximately 1–2 hours. Clinical glucocorticoid effect persists for 12–24 hours due to receptor binding.
2.8-4.5 hours (terminal). Clinical context: short half-life supports once-daily extended-release formulation for colonic delivery.
Renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal (approximately 30%)
Renal: <1%. Fecal: approximately 63% as budesonide and metabolites. Biliary: minor.
