Promethazine Hydrochloride is an antiemetic, antihistaminic, and CNS depressant. Promethazine Hydrochloride a first generation H1 receptor antagonist.This binding process effectively inhibits the activity of histamine, thereby impeding the release of inflammatory mediators. Promethazine hydrochloride interacts with muscarinic receptors, hindering the action of acetylcholine and preventing the release of neurotransmitters.
