Acecainide is a class I antiarrhythmic drug. It was synthesized in the 1970s. Acecainide is a potent sodium channel blocker, which is why it is used to treat supraventricular and ventricular arrhythmias. It was withdrawn from the market due to hepatotoxicity. However, its sodium channel blocking properties have been explored as a potential treatment for other conditions, such as neuropathic pain and epilepsy. Research is ongoing to further explore the potential therapeutic applications of acecainide.'
