While the 5-HT3-mediated phase is short and virtually completed in the first 24 h following chemotherapy administration, the substance P- and NK1-mediated phase in HEC continues for 60–96 h postchemotherapy [25, 26]. The acute phase of chemotherapy has been arbitrary defined as the initial 24 h postchemotherapy and the delayed phase as any time in the 96 h after that. These phase definitions are based on the need for readily measurable endpoints, rather than the biological aspects associated with 5-HT3 and NK1. However, the NK1 RA and 5-HT3 RA are often associated with acute and delayed CINV, respectively. It is apparent that the NK1-mediated effect spans both phases in HEC [25, 27].
