Budiodarone (ATI-2042) is an antiarrhythmic agent and chemical analog of amiodarone that is currently being studied in clinical trials. Amiodarone is considered the most effective antiarrhythmic drug available,[1][2][3] but its adverse side effects, including hepatic, pulmonary and thyroid toxicity as well as multiple drug interactions,[4] are discouraging its use. Budiodarone only differs in structure from amiodarone through the presence of a sec-butyl acetate side chain at position 2 of the benzofuran moiety.[5] This side chain allows for budiodarone to have a shorter half-life in the body than amiodarone (7 hours versus 35–68 days) which allows it to have a faster onset of action and metabolism while still maintaining similar electrophysiological activity.[4] The faster metabolism of budiodarone allows for fewer adverse side effects than amiodarone principally due to decreased levels of toxicity in the body.
