Dimenhydrinate

Common Name

Dimenhydrinate Description

Dimenhydrinate is only found in individuals that have used or taken this drug. It is an over-the-counter drug used to prevent motion sickness. It is closely related to diphenhydramine HCl, or Benadryl. It is primarily a H1-antagonist, but also possesses an antimuscarinic effect.The mechanism by which some antihistamines exert their antiemetic, anti-motion sickness, and antivertigo effects is not precisely known but may be related to their central anticholinergic actions. They diminish vestibliar stimliation and depress labyrinthine function. An action on the medlilary chemoreceptive trigger zone may also be involved in the antiemetic effect. Dimenhydrinate is a competitive antagonist at the histamine H1 receptor, which is widely distributed in the human brain. Dimenhydrinates anti-emetic effect is probably due to H1 antagonism in the vestibliar system in the brain. Structure
