Lansoprazole-d4 is intended for use as an internal standard for the quantification of lansoprazole by GC- or LC-MS. Lansoprazole is a proton pump inhibitor that inhibits the H+/K+-ATPase.1 It inhibits K+ and H+ accumulation in gastric microsomes in a concentration-dependent manner (IC50s = 6.3 and 7 µM, respectively) and inhibits H+/K+-ATPase activity by approximately 60% when used at a concentration of 10 µM. Lansoprazole inhibits the H+/K+-ATPase in parietal cells, thus inhibiting gastric acid secretion and increasing intragastric pH.2 It is a substituted benzimidazole that binds covalently to proton pumps, providing complete and prolonged inhibition of acid secretion.3,4 Formulations containing lansoprazole have been used as a proton pump inhibitor and in combination with antibiotics in the treatment of H. pylori infections and duodenal ulcer disease.

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。
