MedKoo CAT#: 317516

CAS#: 113-92-8

Description: Chlorpheniramine maleate is a histamine H1 antagonist used in allergic reactions, hay fever, rhinitis, urticaria, and asthma. One of the most widely used of the classical antihistaminics, it generally causes less drowsiness and sedation than Promethazine. Although not generally approved as an antidepressant or anti-anxiety medication, chlorphenamine appears to have these properties as well. In addition to being an histamine H1 receptor antagonist, chlorphenamine has been shown to work as a serotonin-norepinephrine reuptake inhibitor or SNRI.
