Meclizine has antiemetic, anticholinergic and antihistaminic properties. It reduces the sensitivity of the labyrinthine apparatus. The action may be mediated through nerve pathways to the vomiting centre (VC) from the chemoreceptor trigger zone (CTZ), peripheral nerve pathways or other CNS centres. Pyridoxine Hydrochloride (Vit - B6), either alone or in combination has been used to prevent nausea & vomiting due to its antiemetic properties.
