用途: Moricizine is an antiarrhythmia agent used primarily for ventricular rhythm disturbances.Target: Sodium ChannelMoricizine is an antiarrhythmia agent used primarily for ventricular rhythm disturbances. Moricizine works by inhibiting the rapid inward sodium current across myocardial cell membranes. Moricizine induced the tonic block of INa with the apparent dissociation constant (Kd,app) of 6.3 microM at -100 mV and 99.3 microM at -140 mV. Moricizine at 30 microM shifted the h infinity curve to the hyperpolarizing direction by 8.6 +/- 2.4 mV. Moricizine also produced the phasic block of INa, which was enhanced with the increase in the duration of train pulses, and was more prominent with a holding potential (HP) of -100 mV than with an HP of -140 mV. Moricizine would exert an antiarrhythmic action on atrial myocytes, as well as on ventricular myocytes, by blocking Na+ channels with a high affinity to the inactivated state and a slow dissociation kinetics [1]. 作用: 吩噻嗪衍生物,钠通道阻滞剂,并有局麻活性。具有中度扩张冠脉,解痉和抗M-胆碱能作用,也具有显著的抗快速性心律失常作用,其作用与奎尼丁相似。用于房性和室性早搏,阵发性心动过速,房颤和房扑有显著疗效。 【用法】 成人口服:每次150-200mg,一日3次或遵医嘱 【副作用】 该品不良反应较轻,可见■系统及消化系统反应,如头晕、口干、胃肠不适等,严重时应减量或停药。 【注意】 房室传导阻滞,窦房阻滞、肝肾功能异常者慎用,该品不得与草胺氧化酶抑制剂合用或接续使用。剂量应个体化,在应用该品前,应停用其他抗心律失常药物1~2个半衰期。 物理化学性质: CAS号:31883-05-3 常用中文名:乙吗噻嗪 常用英文名:Moricizine 分子式:C22H25N3O4S 分子量:427.51700 密度:1.315g/cm3 沸点:625ºC at 760 mmHg 熔点:N/A 闪点:331.8ºC |
