An TV formulation of the class III antiarrhythmic agent amiodarone has
recently received FDA approval The IV formulation is indicated for th
e treatment of recurrent life-threatening ventricular arrhythmias and
for the treatment of patients in whom amiodarone is the drug of choice
but who cannot receive oral therapy. Intravenous amiodarone has been
shown to be efficacious and to possess a favorable safety profile. Wit
h its ease of administration and more rapid onset of action than oral
amiodarone, TV amiodarone represents a useful addition to the antiarrh
ythmic armamentarium in acute situations when other therapy has been u
nsuccessful.
