Application
ピペラジン系のヒスタミンH1受容体アンタゴニスト,メクリジン二塩酸塩

Meclizine hydrochloride, a piperazine class of histamine H1 receptor antagonists, reversibly inhibits the interaction of histamine at the H1 receptors. Meclizine also has anticholinergic activity probably because of its dopamine receptors antagonist activities. In addition, meclizine has been reported to be an inverse agonist of constitutive androstane receptor (CAR). Based on studies conducted on rats, meclizine undergoes extensive hepatic metabolism to an inactive metabolite, norchlorcyclizine or 1-(4-chlorobenzhydryl)piperazine [C1611]. Meclizine hydrochloride is a poorly water-soluble agent having a very slow-onset of action. Therefore, the water solubility enhancement of meclizine hydrochloride has been studied.
