This first-generation antihistamine has anxiolytic, antipruritic, and sedative properties and is used to treat anxiety, itching from allergic conditions, and nausea. It works by blocking histamine H1 receptors and also affects other neurotransmitter systems in the brain. It does not carry the risk of dependence seen with benzodiazepines.

آلية العمل
Enhances the effect of gamma-aminobutyric acid (GABA) at GABA-A receptors by binding to an allosteric site and increasing the frequency of chloride ion channel opening. This produces anxiolytic, sedative, hypnotic, and anticonvulsant effects.
