Enhanced brain motor activity in patients with MS after a single dose of 3,4-diaminopyridine.

Abstract

BACKGROUND 3,4-diaminopyridine (3,4-DAP), a potassium (K+) channel blocker, improves fatigue and motor function in multiple sclerosis (MS). Although it was thought to do so by restoring conduction to demyelinated axons, recent experimental data show that aminopyridines administered at clinical doses potentiate synaptic transmission. OBJECTIVE To… (More)
