The following are medications commonly prescribed cardiac pharmaceutical agents. The specificity of the following medications is highly variable, and often are not particularly specific to a given class. As such, they are listed as are commonly accepted.
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
It is a class IB antiarrhythmic which shorten the refractory period and action potential duration (APD). Decrease in APD more than that of ERP so there is increase ERP/APD ratio. [3] The drug has a bioavailability of 90%, and peak plasma concentrations are seen after 2–4 hours. [3] The mean drug half-life is approximately 11 hours. [3]

Ibutilide is a Class III antiarrhythmic agent that is indicated for acute cardioconversion of atrial fibrillation and atrial flutter of a recent onset to sinus rhythm. It exerts its antiarrhythmic effect by induction of slow inward sodium current, which prolongs action potential and refractory period of myocardial cells. Because of its Class ...
Celivarone is a non-iodinated benzofuran derivative, structurally related to amiodarone, a drug commonly used to treat arrhythmias. [1] Celivarone has potential as an antiarrhythmic agent, attributable to its multifactorial mechanism of action; blocking Na +, L-type Ca 2+ and many types of K + channels (I Kr, I Ks, I KACh and IK v 1.5), as well as inhibiting β 1 receptors, all in dose ...
Moracizine [1] or moricizine, sold under the trade name Ethmozine, is an antiarrhythmic of class IC. [2] It was used for the prophylaxis and treatment of serious and life-threatening ventricular arrhythmias, [3] but was withdrawn in 2007 for commercial reasons.
Acecainide (N-acetylprocainamide, NAPA) is an antiarrhythmic drug. Chemically, it is the N-acetylated metabolite of procainamide. It is a Class III antiarrhythmic agent, whereas procainamide is a Class Ia antiarrhythmic drug. It is only partially as active as procainamide; when checking levels, both must be included in the final calculation.
