What is/are Hydroxyzine?
Hydroxyzine (/haɪˈdrɒksɨziːn/; sold as Vistaril, Atarax) is a first-generation antihistamine of the diphenylmethane and piperazine classes. 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.
Due to its antagonistic effects on several receptor systems in the brain, hydroxyzine is claimed to have strong anxiolytic and mild antiobsessive as well as antipsychotic properties. Today it is used primarily for the symptomatic relief of anxiety and tension associated with psychoneurosis and as an adjunct in organic disease states in which anxiety is manifested. Because of its antihistamine effects it can also be used for the treatment of severe cases of itching, hyperalgesia and motion sickness-induced nausea. Even though it is an effective sedative, hypnotic, analgesic, and tranquilizer, it allegedly shares virtually none of the abuse, dependence, addiction, and toxicity potential of other drugs used for the same range of therapeutic reasons.
Hydroxyzine has been used in medical practice with opioid analgesics to increase the analgesic efficacy of opioids, and by recreational drug users to maximise the effects of opiates, and/or preempt some side effects of opioids like itching, nausea, and vomiting.
