商品名：Thorazine and Largactil
Phenothiazine tranquilizer/antiemetic. Chlorpromazine is a centrally acting dopamine antagonist. It inhibits action of dopamine as neurotransmitter, which may produce some central-acting effects similar to acepromazine and some antiemetic action.
Use in animals has been primarily derived from empirical use. There are no well- controlled clinical studies or efficacy trials to document clinical effectiveness. Chlorpromazine is most often used as a centrally acting antiemetic for disorders that produce vomiting via a central-acting mechanism. It is also used for sedation and preanesthetic purposes, although acepromazine has been much more commonly used.
