Quinidine: A Class 1a Antiarrhythmic Agent

Quinidine, a cinchona alkaloid, originally derived from the bark of the Cinchona tree. Quinidine is a class 1a antiarrhythmic agent which interferes both with the sodium (Na+) and potassium (K+) channels, with a pharmacological profile of action similar to that of disopyramide [D2793]. Quinidine inhibits the fast inward sodium current, and depresses the conduction velocity. Consequently, quinidine decreases myocardial excitability. Its sulfate [Q0010] is used clinically.
