Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias. [4] This includes ventricular tachycardia, ventricular fibrillation, and wide complex tachycardia, atrial fibrillation, and paroxysmal supraventricular tachycardia. [4] Evidence in cardiac arrest, however, is poor. [5]
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.
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.
Increases cardiac contractility, vasodilator. Acts by inhibiting the breakdown of both cAMP and cGMP by the phosphodiesterase enzyme.There is a long-standing controversy regarding whether the drug actually increases cardiac contractility in diseased myocardium (and therefore whether it is of any clinical use).
The related medication eplerenone was shown in the EPHESUS trial [31] to have a similar effect, and it is specifically labelled for use in decompensated heart failure complicating acute myocardial infarction. While the antagonism of aldosterone will decrease the effects of sodium and water retention, it is thought that the main mechanism of ...
Drugs that are effective at maintaining normal rhythm after electric cardioversion can also be used for pharmacological cardioversion. Drugs like amiodarone, diltiazem, verapamil and metoprolol are frequently given before electrical cardioversion to decrease the heart rate, stabilize the patient and increase the chance that cardioversion is ...
Nitrates (e.g., nitroglycerin, isosorbide dinitrate or isosorbide mononitrate) used to treat congestive heart failure and chest pain. ... Ketoconazole, a drug used to treat certain fungal infections.
PDE3 inhibitors are indicated as inotropics for the therapy of acute heart failure if catecholamines are ineffective. [2] Well controlled studies have shown that these drugs generally increase mortality, [3] when used for the therapy of acute heart failure, so they have to be applied under close observation. [1]
