依美司丁性质、用途与生产工艺
依美斯汀（Emedastine，商品名称： Emadine）是第二代抗组织胺，可用作眼药水以减缓过敏性结膜炎的症状。依美斯汀属于H1 接收器抑制剂。借由抑制组织胺的作用来减缓过敏性结膜炎的症状。当依美斯汀用作眼药水时，会以双延胡索酸盐（difumarate）的形式存在。
Emedastine 是一种具有口服活性，选择性和高亲和力的组胺 H1 受体拮抗剂，Ki 值为 1.3 nM。Emedastine 是一种苯并咪唑衍生物，具有强大的抗过敏特性，可用于过敏性鼻炎，过敏性皮肤疾病和过敏性结膜炎。

1.3 nM(Ki)
|
Emedastine inhibits histamine H
2
receptor (K
i
=49067 nM) and histamine H
3
receptor (K
i
=12430 nM).
High concentrations of Emedastine (1 and 10 ng/ml) significantly inhibits type 1 collagen production in normal human dermal fibroblasts.
Emedastine (1, 10, 100, 1000 nM) at concentrations of ≥ 10 nM inhibits CC chemokine-elicited eosinophil migration.
Emedastine (0.03, 0.1, 0.3 mg/kg; orally; pretreatment of 30 min) significantly suppresses histamine-induced scratching with 0.1 and 0.3 mg/kg but not 0.03 mg/kg.
Pretreatment with Emedastine (0.03, 0.1, 0.3 mg/kg; orally) significantly inhibits the scratching induced by substance P and leukotriene B.
Emedastine (0.3 mg/kg, p.o.) produces significant inhibition of passive peritoneal anaphylaxis in guinea-pigs.
Emedastine inhibits histamine-induced contractions of isolated ileum (IC
50
=6.1 nM).
