Budiodarone is a chemical analog of amiodarone with mixed ion channel electrophysiological activity. Budiodarone was developed to capitalize on the proven efficacy of amiodarone and to avoid its side effects. Budiodarone has a short plasma half-life (7 h) and a lower volume of distribution (13 L/kg). It is cleared from the body in 48 h. Like amiodarone, Budiodarone has balanced, multiple cardiac ion channel inhibiting activity, giving it properties of all four Vaughan Williams antiarrhythmic drug classes. Budiodarone, unlike amiodarone, undergoes rapid metabolism by plasma and tissue esterases. In clinical trials, Budiodarone effectively reduces the number and duration of atrial tachycardia/atrial fibrillation episodes.
