Description

Meclizine dihydrochloride is a human pregnane X receptor (hPXR) agonist and histamine H1 receptor antagonist. Meclizine dihydrochloride is stronger activator of hPXR than rat PXR. Meclizine dihydrochloride increases hPXR target gene expression in human hepatocyte primary cultures. Meclizine dihydrochloride is an antihistamine considered to be an antiemetic. Meclizine dihydrochloride possesses anticholinergic, central nervous system depressant, and local anesthetic effects. Meclizine dihydrochloride depresses labyrinth excitability and vestibular stimulation, and it may affect the medullary chemoreceptor trigger zone. Meclizine dihydrochloride is used to treat or prevent nausea, vomiting, and dizziness caused by motion sickness.
