Nausea butyrophenones

The pharmacology of all these neuroleptics is extremely complex. Briefly, phenoth-iazines and related drugs have a calming effect on psychotic patients, without producing excessive sedation. Other central effects include the important antiemetic effect in disease-, drug-, or radiation-induced nausea, but not so much in motion sickness. Butyrophenones are more effective antiemetics than phenothiazines and also potentiate the activity of anesthetics.
