Chlorcyclizine

Chlorcyclizine (Di-Paralene, Mantadil, Pruresidine, Trihistan) is a first-generation antihistamine of the diphenylmethylpiperazine group marketed in the United States and certain other countries.[1][2][3] It is used primarily to treat allergy symptoms such as rhinitis, urticaria, and pruritus, and may also be used as an antiemetic.[1][2][3] In addition to its antihistamine effects, chlorcyclizine also has some anticholinergic, antiserotonergic, and local anesthetic properties.[4][5] It also has been studied as a potential treatment for various flaviviruses like Hepatitis C and Zika Virus.[6][7][8]
