Description

Nerispirdine, an acetylcholine release enhancer and a K+/Na+ use-dependent channel blocker, was in clinical development with sanofi-aventis for the treatment of multiple sclerosis. Nerispirdine is not proconvulsant. It can inhibit axonal K(+) channels and this mechanism may underlie the ability of the drug to enhance neuronal conduction. Nerispirdine can also inhibit neuronal Na(+) channels, a mechanism that may explain why nerispirdine lacks proconvulsant activity.

Route of Administration: Oral
In Vitro Use Guide
Nerispirdine inhibited K(v)1.1 and K(v)1.2 with IC(50) values of 3.6 and 3.7 umol/L, respectively. Nerispirdine also inhibited voltage-dependent Na(+) channel currents recorded from human SH-SY5Y cells with an IC(50) of 11.9 umol/L when measured from a -70 mV holding potential.
