Norpace
Norpace is the brand name for disopyramide, an antiarrhythmic medication in the class IA category. It works by blocking fast sodium channels in cardiac tissue and also has some potassium channel blocking effects, which together prolong the cardiac action potential and the refractory period. This action helps stabilize abnormal electrical activity in certain heart rhythms.
Norpace is used to treat a range of arrhythmias in adults, including ventricular tachycardia and certain supraventricular
Contraindications to Norpace include known hypersensitivity to disopyramide, significant left ventricular dysfunction or heart failure, and
Norpace should be used under close medical supervision with appropriate monitoring of heart rhythm and electrolytes.
