Methazolamide-d6 is intended for use as an internal standard for the quantification of methazolamide by GC- or LC-MS. Methazolamide is a carbonic anhydrase inhibitor (IC50 = 130 nM).1 It reduces intraocular pressure and cerebrospinal fluid flow in a rat model of glaucoma. Methazolamide reduces electroshock-induced seizures in rats with an ED50 value of 19.2 mg/kg.2 It also inhibits production of reactive oxygen species (ROS) in a primary cortical neuron (PCN) cellular model of subarachnoid hemorrhage (SAH) and reduces cerebral edema in a mouse model of SAH.3 Methazolamide is larvicidal, with a 50% larvicidal concentration (LC50) value of 724 ppm, but has no activity when administered in the diet to adult A. aegypti.4 Formulations containing methazolamide have been used in the treatment of glaucoma.

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。
