DEXONE 4 vs TARPEYO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
TARPEYO (budesonide) is a corticosteroid with anti-inflammatory activity. It acts by binding to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines and immune cell activation, thereby reducing proteinuria in IgA nephropathy.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
16 mg/kg intravenously once daily on Days 1-5 of each 28-day cycle.

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Terminal elimination half-life is approximately 27.3 hours (range 21-36 hours) in patients with IgA nephropathy. This supports once-weekly subcutaneous dosing without dose adjustment over the dosing interval.
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Primarily hepatic metabolism, with <1% excreted unchanged in urine and <1% in feces. Elimination is predominantly via biliary excretion of metabolites into feces, accounting for >90% of total clearance.
