Anticipatory nausea and vomiting in the era of 5-HT3 antiemetics.

ABSTRACT

Cancer chemotherapy is known to lead to nausea and vomiting in a large proportion of cases. If emesis is severe it can lead in its turn to anticipatory nausea and vomiting (ANV), which cannot be controlled by antiemetic medication. The etiology of ANV and various methods that have been used to counteract the condition are discussed.
