129-71-5 Usage
General Description
Chlorcyclizine dihydrochloride is a synthetic antihistamine that belongs to the class of piperazine compounds. It was initially developed to treat allergic reactions, such as hay fever or urticaria, due to its ability to inhibit the biological effect of histamine by blocking histamine receptors. This causes a reduction in capillary permeability, relieving symptoms like itching and redness. Recently, it has also been studied for its potential antiviral properties, particularly against the hepatitis C virus. It is also used for alleviating symptoms of the common cold and rhinitic symptoms. Chlorcyclizine dihydrochloride comes under the category of first-generation antihistamines, hence it can cause sedation.
