Disopyramide phosphate

Disopyramide phosphate is a class Ia antiarrhythmic agent with cardiac depressant properties. Disopyramide phosphate exerts its actions by blocking both sodium and potassium channels in cardiac membrane during phase 0 of the action potential. This slows the impulse conduction through the AV node and prolongs the duration of the action potential of normal cardiac cells in atrial and ventricular tissues. The directory classifies it as a commercial API with a synthetic source/manufacturing origin. Other names for this substance include Rythmodan and Norpace. Its PubChem CID is 30928.
