CERADON vs EXSERVAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Unknown; possibly enhances cognitive function by modulating cholinergic and dopaminergic pathways.
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.
500 mg orally every 8 hours; for severe infections, 750 mg every 12 hours or 1 g every 8 hours.
Adults: 15 mg orally once daily in the morning; increase to 30 mg after 2 weeks if needed. Maximum 30 mg/day.

3-5 hours in healthy adults; prolonged to 8-12 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 20 hours in severe impairment (CrCl <30 mL/min).
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).
Renal: 60-70% unchanged; biliary/fecal: 20-30% as metabolites; total: >90% eliminated within 48 hours.
Primarily renal excretion as unchanged drug: 80% excreted unchanged in urine; approximately 20% as metabolites; biliary/fecal <5%.
