RT Journal Article SR Electronic T1 Successuful treatment of paramyotonia congenita (Eulenburg): muscle stiffness and weakness prevented by tocainide. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 268 OP 271 DO 10.1136/jnnp.43.3.268 VO 43 IS 3 A1 K Ricker A1 A Haass A1 R Rüdel A1 R Böhlen A1 H G Mertens YR 1980 UL http://jnnp.bmj.com/content/43/3/268.abstract AB 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.
