CORVERT (ibutilide fumarate)

Cardiovascular Approved 1995-12-28

Corvert is an injectable medication used to quickly return the heart to a normal rhythm in patients experiencing recent-onset atrial fibrillation or atrial flutter. It helps patients whose heart rhythm disturbances have started recently, as it is less effective for those who have had these conditions for more than 90 days. This drug works to convert these specific irregular heartbeats back to a steady sinus rhythm.

How CORVERT Works

This drug works by prolonging the duration of the heart's action potential and increasing the time the heart muscle needs to recover between beats. It achieves this by activating a slow, inward sodium current to delay the repolarization of cardiac cells, rather than blocking potassium currents. These electrical changes in the heart are the basis for its ability to stop irregular rhythms.

CORVERT Boxed Warning

LIFE-THREATENING ARRHYTHMIAS—APPROPRIATE TREATMENT ENVIRONMENT CORVERT can cause potentially fatal arrhythmias, particularly sustained polymorphic ventricular tachycardia, usually in association with QT prolongation (torsades de pointes), but sometimes without documented QT prolongation. In registration studies, these arrhythmias, which require cardioversion, occurred in 1.7% of treated patients during, or within a number of hours of, use of CORVERT. These arrhythmias can be reversed if treated ...
