Disopyramide
A class IA antiarrhythmic drug used to treat and prevent ventricular arrhythmias and atrial fibrillation by blocking sodium channels in the heart, slowing conduction and reducing excitability. It also has significant anticholinergic effects, causing dry mouth, urinary retention, and constipation. It has negative inotropic effects and must be used cautiously in patients with heart failure.
