Hydroxyzine (/haÉªËdrÉksÉ¨ziËn/ ; sold as Vistaril, Atarax) is a first-generation antihistamine of the diphenylmethane and piperazine class.It was first synthesized by Union Chimique Belge in 1956 and was marketed by Pfizer in the United States later the same year, and is still in widespread use today.ydroxyzine's predominant mechanism of action is as a potent H1 receptor inverse agonist (K i = 2 nM).
