EXSERVAN vs TARPEYO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Exservan (riluzole) is a benzothiazole derivative that modulates glutamatergic neurotransmission. Its mechanism of action involves inhibition of glutamate release, inactivation of voltage-dependent sodium channels, and interference with neurotransmitter binding to excitatory amino acid receptors.
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.
Adults: 15 mg orally once daily in the morning; increase to 30 mg after 2 weeks if needed. Maximum 30 mg/day.
16 mg/kg intravenously once daily on Days 1-5 of each 28-day cycle.

Terminal elimination half-life is approximately 3–4 hours in patients with normal renal function; prolonged in renal impairment (up to 8–10 hours in ESRD).
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.
Primarily renal excretion as unchanged drug: 80% excreted unchanged in urine; approximately 20% as metabolites; biliary/fecal <5%.
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.
