What drug is used for short term treatment of cardiac dysrhythmia?
The most common medications in this class are: amiodarone (Cordarone, Pacerone) flecainide (Tambocor) ibutilide (Corvert), which can only be given through IV.
What is the safest antiarrhythmic drug?
Dronedarone was the best tolerated of the antiarrhythmic drugs, with the lowest rates of severe adverse events and a significant reduction in the risk of stroke. It is our practice to use propafenone, flecainide, sotalol, and dronedarone as first-line therapies in patients without structural heart disease (Table 4).
What is the best antiarrhythmic drug?
Cordarone is a truly unique antiarrhythmic drug. While it is more effective than any other drug in treating atrial fibrillation, and while it causes relatively little proarrhythmia, it is exceedingly likely to cause other side effects that can be quite significant and even life-threatening.
What is an Antidysrhythmic drug?
Antidysrhythmic agents, which are also known as antiarrhythmic agents, are a broad category of medications that help ameliorate the spectrum of cardiac arrhythmias to maintain normal rhythm and conduction in the heart.
What are the classes of Antidysrhythmic drugs?
Antiarrhythmic drugs are grouped into four main classes:
- Class I, sodium-channel blockers;
- Class II, beta-blockers;
- Class III, potassium-channel blockers;
- Class IV, calcium-channel blockers; and.
- miscellaneous antiarrhythmics or unclassified antiarrhythmics.
Are arrhythmia drugs safe?
Antiarrhythmic agents can have serious side effects. Systemic adverse effects are usually use-related and reversible with withdrawal of the drug. Impairment of left ventricular function is considerable in patients with heart failure.
Which three drugs are commonly used for atrial fibrillation?
Three types of medications can be used to restore your normal heart rate:
- Beta-blockers such as atenolol (Tenormin), carvedilol (Coreg), and propranolol (Inderal)
- Calcium channel blockers such as diltiazem (Cardizem) and verapamil (Verelan)
- Digoxin (Lanoxin)
What is the main goal Use of Antidysrhythmic drug therapy?
The goal of treatment is to either (1) terminate the dysrhythmia or (2) prevent excessive atrial beats from reaching the ventricles (using a beta blocker, calcium channel blocker, or digoxin). In contrast to supraventricular dysrhythmias, ventricular dysrhythmias frequently interfere with pumping.
