一般描述

左西替利嗪二盐酸盐是西替利嗪的R-对映体,可用于治疗季节性过敏性鼻炎和慢性特发性荨麻疹。肝脏可代谢14%的左西替利嗪,而其余的可通过尿液被排出体外。左西替利嗪对组胺的反应相对于西替利嗪较高。

应用

左西替利嗪二盐酸盐已被用作薄层色谱优化的标准品,并用于亚临界流体色谱-串联质谱分析的外消旋西替利嗪标准品的制备中。

生化/生理作用

盐酸左西替利嗪是一种非镇静抗组胺药。它是一种组胺H1受体拮抗剂,西替利嗪的活性异构体。左西替利嗪对H1受体具有较高的生物利用度、高亲和力和占据度。

Histamine is a well-known mediator involved in skin allergic responses through up-regulation of pro-inflammatory cytokines. Antihistamines remain the mainstay of allergy treatment, but they were found limited in efficacy and associated with several common side effects. Therefore, alternative therapeutic preferences

Cetirizine is a zwitterionic second-generation antihistamine containing R- and S-enantiomers, levocetirizine, and (S)-cetirizine. Levocetirizine is known to have a higher affinity for the histamine H₁ receptors than (S)-cetirizine; ligand-receptor docking simulations have suggested the importance of the formation of a
