Class I antiarrhythmic drugs, also known as sodium channel blockers, are classified into three subgroups such as class Ia (quinidine, procainamide, disopyramide, acecainide), class Ib (lidocaine, mexiletine, tocainide, phenytoin), and class Ic (propafenone, flecainide, encainide, moricizine)....
Figure 5. Examples of class 1b antiarrhythmics. • Toxicity: The toxicity of class 1b drugs includes loss of SA and AV node pacing resulting in a lack of a heart beat (asystole). CNS symptoms are common, and include initial paresthesias with subsequent convulsions. This is a result of...

Two types of sodium channel block by class-I antiarrhythmic drugs studied by using Vmax of action potential in single ventricular myocytes. The state-dependent sodium channel block by mexiletine, tocainide, lidocaine, OPC-88117, aprindine, quinidine, disopyramide and AN-132 was investigated in .....
