英文名称:Ibutilide Fumarate 中文名称:富马酸伊布利特 CAS:122647-32-9 分子式:(C20H36N2O3S)2·C4H4O4 分子量:885.23 产品说明:Ibutilide Fumarate is the fumarate salt form of ibutilide, a class III antiarrhythmic agent. Ibutilide exerts its effect by activating a slow, inward, predominately sodium current rather than by blocking outward potassium currents. This results in prolongation of atrial and ventricular action potential duration and refractory periods. Ibutilide slightly decreases the sinus rate and atrioventricular (AV) conduction and produces a dose-related prolongation of the QT interval.
