title: Successuful treatment of paramyotonia congenita (Eulenburg): muscle stiffness and weakness prevented by tocainide.
abstract: Recent studies have shown that the sodium conductance of the sarcolemma is disturbed in paramyotonia. Tocainide is a new antiarrhythmic agent which seems to reduce effectively sodium conductance. Eight patients with paramyotonia were treated with tocainide, whereby the paramyotonic stiffness and weakness brought about by cooling could be prevented.
