Ondansetron blocks the start of this reflex. Enactment of vagal afferents may moreover cause a discharge of 5HT within the zone postrema, found on the floor of the fourth ventricle, and this may moreover advance emesis through a central component. In this way, the impact of ondansetron within the administration of the sickness and spewing actuated by cytotoxic chemotherapy and radiotherapy is likely due to enmity of 5HT3 receptors on neurons found both within the fringe and central apprehensive framework.
