A class III antiarrhythmic drug that prolongs the action potential duration and refractory period in cardiac tissue, also possessing some class I, II, and IV properties. It is used for rhythm control in atrial fibrillation and for ventricular tachycardia/fibrillation, but requires careful monitoring due to significant potential side effects.

It has a wide range of potential serious side effects affecting the lungs (pneumonitis, fibrosis), thyroid (both hyper- and hypothyroidism), liver, eyes, and skin. It also interacts with many other medications.

Generally, no. Due to its side-effect profile, it is often considered after other, safer antiarrhythmic drugs have been tried or are contraindicated, except in specific emergency situations like cardiac arrest with shock-refractory ventricular arrhythmias.

It can be given intravenously in hospital emergencies for rapid effect, or orally in tablet form for long-term maintenance therapy. An oral loading dose phase is typically required to achieve effective blood levels.
