Description:

WARNING: This product is for research use only, not for human or veterinary use.

Dimenhydrinate is an antihistamine primarily used to prevent and treat nausea, vomiting, and dizziness associated with motion sickness. It is a salt compound composed of diphenhydramine and 8-chlorotheophylline, combining H₁ receptor antagonism with mild CNS stimulation to reduce drowsiness. Its bioactivity stems from diphenhydramine's ability to block histaminergic signaling in the vestibular system and chemoreceptor trigger zone, dampening neural input that triggers emesis.
