Main Medicine Class:: #N/A  Sub Medicine Class :: #N/A 

Indications for Drugs ::

Ventricular arrhythmias, Ventricular fibrillation, Ventricular tachycardia, Atrial fibrillation, Hypertrophic cardiomyopathy, Supraventricular arrhythmias

Drug Dose ::

Oral Ventricular arrhythmias Adult: 800-1,600 mg/day in 1-2 divided doses for 1-3 wk until initial therapeutic response is achieved, then reduce dose to 600-800 mg/day in 1-2 divided doses for 1 mth. Maintenance: 400 mg/day; lower doses may be used for supraventricular arrhythmias. Daily doses may be divided. Close monitoring of the patient is recommended. Use the minimum effective dose. Hepatic impairment: Dosage reduction may be necessary.

Contraindication ::

Hypersensitivity to amiodarone or iodine. Severe sinus node dysfunction, 2nd and 3rd degree heart block (except in patients with a functioning artificial pacemaker), cardiogenic shock, pregnancy.

Drug Precautions ::

Close monitoring is recommended as amiodarone may worsen arrhythmia especially when used concurrently with other anti-arrhythmic drugs or drugs that prolong QT interval. May cause hypotension and bradycardia. May increase risk of liver toxicity. May cause visual disturbance/impairment; corneal refractive laser surgery is not recommended in patients on amiodarone treatment. May cause lung damage; monitor for pulmonary toxicity e.g. acute respiratory distress syndrome. Monitor liver functions regularly. May affect defibrillation or pacing thresholds of cardiac devices. Correct electrolyte imbalance before starting treatment. Caution when used in patients undergoing surgery. Avoid excessive sunlight exposure due to increased risk of photosensitivity. Hepatic impairment, thyroid disease, elderly. Lactation.

Drug Side Effects ::

Blue-grey discolouration of skin, photosensitivity, peripheral neuropathy, paraesthesia, myopathy, ataxia, tremor, nausea, vomiting, metallic taste, hypothyroidism, hyperthyroidism, alopoecia, sleep disturbances, corneal microdeposits, hot flushes, sweating. Heart block, bradycardia, sinus arrest, hepatotoxicity, heart failure. Potentially Fatal: Pulmonary toxicity including pulmonary fibrosis and interstitial pneumonitis, hepatotoxicity, thyrotoxicity. Ventricular arrhythmias, pulmonary alveolitis, exacerbation of arrhythmias and rare serious liver injury. Generally in patients with high doses and having preexisting abnormalities of diffusion capacity.

Pregnancy category ::

Drug Mode of Action ::  

Amiodarone is a class III antiarrhythmic agent which inhibits stimulation, prolongs action potential and refractory period in myocardial tissues. It also decreases AV conduction and sinus node function. Sinus rate is reduced by 15-20%, PR and QT intervals are increased. Amiodarone can cause marked sinus bradycardia or sinus arrest and heart block. In acute IV doses, amiodarone may exert a mild negative inotropic effect.

Drug Interactions ::

Potentiation of antiarrhythmic drugs. Possible increased risk of adverse effects when used with anaesthetic agents. Monitor plasma levels of amiodarone when used with HIV protease inhibitors. Cimetidine may increase serum levels of amiodarone. Concurrent use may increase serum levels of ciclosporin. May increase risk of myopathy or rhabdomyolysis when used with HMG-CoA reductase inhibitors. Rifampin may reduce the serum levels of amiodarone. Potentially Fatal: Potentiates the effect of warfarin and other anticoagulants hence dose of warfarin generally needs to be reduced approx half. Raised plasma concentrations of digoxin, phenytoin and quinidine. Additive effect with beta-blockers and calcium-channel blockers (e.g. verapamil and diltiazem).
