Product Overview

Diphenhydramine hydrochloride is a first-generation antihistamine medication widely used for the treatment of allergic conditions, motion sickness, and as a sleep aid. It is also a key ingredient in various combination formulations for cold and flu relief. Diphenhydramine HCl API has strong H1 receptor antagonist, anticholinergic, antiemetic, and sedative properties, making it a versatile active pharmaceutical ingredient for numerous drug formulations. CN-ConnectWorld supplies pharmaceutical-grade Diphenhydramine hydrochloride raw material with consistent quality.

Mechanism of Action

Diphenhydramine works by competitively inhibiting histamine H1 receptors, blocking histamine-mediated allergic responses in the body. Its anticholinergic properties contribute to its sedative and antiemetic effects. The sedative action results from H1 receptor blockade in the CNS, making it useful as a sleep aid. Its antiemetic properties make it effective against motion sickness and nausea.
