A double-blind, single crossover study of chronic oral taurine administration versus placebo was conducted on nine patients with dystrophia myotonica. The severity of myotonia was assessed by clinical and electromyographic criteria and by testing the sensitivity of myotonic muscles to the intra-arterial infusion of potassium chloride. Confirming the antimyotonic effect of acute parenteral taurine, chronic treatment induced significant improvement of myotonia and a decreased sensitivity to the arterial potassium load as well as an enhancement of electrolyte movements across the membrane of the studied muscles. No significant side effects were noted.

Abstract
A double-blind, single crossover study of chronic oral taurine administration versus placebo was conducted on nine patients with dystrophia myotonica. The severity of myotonia was assessed by clinical and electromyographic criteria and by testing the sensitivity of myotonic muscles to the intra-arterial infusion of potassium chloride. Confirming the antimyotonic effect of acute parenteral taurine, chronic treatment induced significant improvement of myotonia and a decreased sensitivity to the arterial potassium load as well as an enhancement of electrolyte movements across the membrane of the studied muscles. No significant side effects were noted.
