Phenothiazines antagonize the dopamine D2-receptor in the chemoreceptor trigger zone (CTZ) of the brain, potentially preventing chemotherapy-induced emesis.  In addition, these agents have peripherally or centrally antagonistic activity against alpha adrenergic, serotonergic, histaminic, and muscarinic receptors. (NCI)"}]
