Therapeutic indications:

Because of its life-threatening side effects and the substantial management difficulties associated with its use (see WARNINGS below), amiodarone is indicated only for the treatment of the following documented, life-threatening recurrent ventricular arrhythmias when these have not responded to documented adequate doses of other available antiarrhythmics or when alternative agents could not be tolerated. - Recurrent ventricular fibrillation. - Recurrent hemodynamically unstable ventricular tachycardia. As is the case for other antiarrhythmic agents, there is no evidence from controlled trials that the use of amiodarone hydrochloride tablets favorably affects survival. Amiodarone should be used only by physicians familiar with and with access to (directly or through referral) the use of all available modalities for treating recurrent life-threatening ventricular arrhythmias, and who have access to appropriate monitoring facilities, including in-hospital and ambulatory continuous electrocardiographic monitoring

dioxide, corn starch, lactose monohydrate, magnesium stearate,
povidone and sodium starch glycolate.
CLINICAL PHARMACOLOGY
ELECTROPHYSIOLOGY/MECHANISMS OF ACTION:
In animals, amiodarone is effective in the prevention or suppression
of experimentally induced
arrhythmias. The antiarrhythmic effect of amiodarone may be due to at
least two major properties:
1. a prolongation of the myocardial cell-action potential duration and
refractory period and
2. noncompetitive α- and β-adrenergic inhibition.
Amiodarone prolongs the duration of the action potential of all
cardiac fibers while causing minimal
reduction of dV/dt (maximal upstroke velocity of the action
potential). The refractory period is
prolonged in all cardiac tissues. Amiodarone increases the cardiac
refractory period without
influencing resting membrane potential, except in automatic cells
where the slope of the prepotential is
reduced, generally reducing automaticity. These electrophysiologic
effects are reflected in a
decreased sinus rate of 15 to 20%, increased PR and QT intervals of
about 10%, the development of U-
waves, and changes in T-wave contour. These changes should not require
discontinuation o
