Hydroxyzine is a piperazine derivative, a sedating antihistamine with antimuscarinic effects that competitively blocks histamine H1-receptors on effector cells of the gastrointestinal tract, blood vessels, and respiratory tract, thereby inhibiting H1-receptor-mediated reactions such as vasodilation, flare, and itch reactions, and sneezing. It possesses a skeletal muscle-relaxing, bronchodilating, antiemetic, and analgesic properties.
