Abstract

In the last few years there has been a marked upsurge of interest in research regarding the neural mechanisms of control of nausea and vomiting, following the recent recognition (Miner and Sanger, 1986) that a poorly understood class of drugs has potent antiemetic properties for some forms of emesis. In particular, these drugs appear to be selective for emesis that is experienced by most cancer patients when they receive chemotherapy or radiotherapy for their condition. The drugs are ‘blockers’ of the ‘M’ type of serotonin (5-HT) receptor of Gaddum and Picarelli (1957), which is now classified as the 5-HT3 receptor (Bradley et al., 1986). Since the somewhat startling discovery that 5-HT3 receptor antagonists can be so potent and selective in this regard, a host of new drugs has been developed by several pharmaceutical companies to introduce even more potent and more selective drugs of this type.
