You'd have better luck looking up phenothiazines. A common one is Thorazine. http://webmd.lycos.com/content/asset/uspdi.202457#Description Phenothiazines (FEE-noe-THYE-a-zeens) are used to treat serious mental and emotional disorders, including schizophrenia and other psychotic disorders. Some are used also to control agitation in certain patients, severe nausea and vomiting, severe hiccups, and moderate to severe pain in some hospitalized patients. Chlorpromazine is used also in the treatment of certain types of porphyria, and with other medicines in the treatment of tetorifice. [This message has been edited by roise (edited December 21, 2000).]
