Ketotifen-13C-d3 is intended for use as an internal standard for the quantification of ketotifen by GC- or LC-MS. Ketotifen is a histamine H1 receptor antagonist (Ki = 1.3 nM) and mast cell stabilizer.1,2 It is selective for H1 receptors over H2 and H3 receptors (Kis = 987 and 2,500 nM, respectively).1 Ketotifen (50 and 100 μM) inhibits degranulation of rat peritoneal mast cells induced by compound 48/80 .2 It inhibits the passive cutaneous anaphylaxis (PCA) reaction in rats by 54.6% when administered orally at a dose of 20 mg/kg.3 Ketotifen (30 mg/kg) inhibits the quick phase airway response in a rat ovalbumin-induced immediate airway response model.4 Formulations containing ketotifen have been used in the treatment of itching associated with allergic conjunctivitis.

计算结果:
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。
