WebClass Ic drugs are more potent antiarrhythmics than either class Ia or class Ib drugs. Class Ic drugs do not block potassium channels directly. Class Ic drugs may organize and slow atrial tachyarrhythmias enough to permit 1:1 AV conduction with marked acceleration of the ventricular response rate. WebClass IA Drugs: Class IA drugs used in veterinary medicine include quinidine and procainamide. Quinidine is related to the antimalarial drug quinine. In addition to its membrane-stabilizing properties inherent to Class I agents, it also has indirect, antivagal (“atropine-like”) effects in the atria. ...
