How do you memorize antiarrhythmic drugs?
The mnemonic to remember the different classes of antiarrhythmic medications is “Some Block Potassium Channels”. “Some” = Sodium channel blockers = Class I antiarrhythmics. “Block” = Beta blockers = Class II antiarrhythmics. “Potassium” = Potassium channel blockers = Class III antiarrhythmics.
What are the classes of antiarrhythmic drugs give examples?

|---|---|---|
| Class | Examples | |
| Class I antiarrhythmics | Class IB antiarrhythmics | Lidocaine Mexiletine Phenytoin |
| Class IC antiarrhythmics | Flecainide Propafenone | |
| Class II antiarrhythmic drugs | Metoprolol Esmolol (short acting) Propranolol Atenolol Timolol Carvedilol Sotalol |
What class is procainamide?
Procainamide is a medication used to manage and treat ventricular arrhythmias, supraventricular arrhythmias, atrial flutter/fibrillation, and Wolf-Parkinson-White syndrome. It is in the antiarrhythmic Agent Class 1A class of medications.
What are Class 3 antiarrhythmic drugs?
Amiodarone, sotalol, dofetilide, and ibutilide are examples of class III drugs that are currently available. Amiodarone and sotalol have other antiarrhythmic properties in addition to pure class III action, which differentiates them from the others. However, all have potential serious adverse events.
What is a class 3 antiarrhythmic?
Class III antiarrhythmic drugs act by blocking repolarising currents and thereby prolong the effective refractory period of the myocardium. This is believed to facilitate termination of re-entry tachyarrhythmias. This class of drugs is developed for treatment of both supraventricular and ventricular arrhythmias.
Is amlodipine a dihydropyridine?
Dihydropyridines — The dihydropyridines, including nifedipine, isradipine, felodipine, nicardipine, nisoldipine, lacidipine, amlodipine, and levamlodipine are potent vasodilators that have little or no negative effect clinically upon cardiac contractility or conduction.
What are antiarrhythmic drugs?
Antiarrhythmic drugs. Part 1: an overview Antiarrhythmic drugs are a broad class of medicines with a variety of indications, mechanisms and unique features. Some are widely used because of their relatively benign nature, while others require careful supervision because of a greater potential for adverse effects.
What are the limitations of antiarrhythmic drugs?
Proarrhythmia is an important limitation of all anti- al, 2013). Antiarrhythmic drugs that terminate arrhythmias or prevent their recurrence are commonly referred to as rhythm control drugs. The other important concept to consider is the role of the AV node.
What are the possible side effects of class Ia antiarrhythmics?
Other side effects of class Ia antiarrhythmics are more drug-specific. Procainamide may induce lupus erythematosus that is reversible after discontinuation of the offending drug.
What is the best antiarrhythmic drug for SVT?
Other antiarrhythmic drugs Adenosine is useful for diagnosis and termination of SVT due to either atrioventricular nodal reentrant tachycardia (AVNRT) or orthodromic atrioventricular reentrant tachycardia (AVRT). This drug may also be utilized diagnostically; adenosine helps to unmask atrial flutter or atrial tachycardia (AT).
