Esmolol acid is an active metabolite of the β1-adrenergic receptor (β1-AR) antagonist esmolol .1 It is formed from esmolol via hydrolysis by a red blood cell esterase. Esmolol acid inhibits isoproterenol-induced increases in the beating rate of isolated guinea pig right atria (pA2 = 3.73) and prevents tachycardia and hypotension induced by isoproterenol in anesthetized dogs in a dose-dependent manner.2 It is also a potential impurity in commercial preparations of esmolol.3

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
