EXSERVAN vs PREDNISONE INTENSOL
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.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Adults: 15 mg orally once daily in the morning; increase to 30 mg after 2 weeks if needed. Maximum 30 mg/day.
5-60 mg orally once daily or divided twice daily, titrated to response.

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).
2-4 hours (terminal) for prednisone; prednisolone half-life 2-4 hours. Clinical context: shorter than anti-inflammatory effect due to delayed receptor-mediated action.
Primarily renal excretion as unchanged drug: 80% excreted unchanged in urine; approximately 20% as metabolites; biliary/fecal <5%.
Renal: <30% unchanged; major metabolites (prednisolone, 20-dihydroprednisolone) conjugated and excreted in urine. Fecal: <10%.
