A comparative study of disopyramide and procainamide in the treatment of myotonia in myotonic dystrophy.
Abstract
Ten patients with myotonic dystrophy were allocated at random to treatment with disopyramide and procainamide in a cross-over trial. Disopyramide was found to be at least as effective as procainamide in the relief of myotonia; and two patients who could not tolerate procainamide both tolerated disopyramide.
