Mechanism of Action
Diphenhydramine Hydrochloride works by acting as an inverse agonist at peripheral and central H1-histamine receptors. It inhibits the physiological effects of histamine on vascular smooth muscle, bronchial passages, and gastrointestinal tracts to help the body alleviate acute allergic flare-ups. Unlike second-generation antihistamines, it crosses the blood-brain barrier readily, binding to central H1 receptors to provide predictable sedative and antiemetic outcomes. It is highly effective and well-tolerated for emergency medical applications.
