Guidelines for antiemetic therapy, such as the American Society of Clinical Oncology (ASCO) guidelines, recommend that aprepitant, an NK1 receptor antagonist, should be used in addition to conventional antiemetic therapy for acute and delayed nausea/vomiting caused by highly emetogenic chemotherapy. However, only few studies have been conducted to evaluate the efficacy of aprepitant in patients receiving moderately emetogenic chemotherapy. Therefore, we examined the antiemetic effects of additional doses of aprepitant in the next course in patients with lung cancer who were undergoing chemotherapy with carboplatin and who developed chemotherapy-induced nausea and vomiting (CINV) despite the preventive administration of a 5-HT3 receptor antagonist and dexamethasone. Consequently, the incidences of vomiting and nausea significantly decreased from 59% to 0% and from 91% to 64%, respectively, during the entire study period. Furthermore, a significant improvement in dietary intake during the entire study period was confirmed. These results suggest that the additional administration of aprepitant has high antiemetic effects in patients with lung cancer who are undergoing chemotherapy with carbo- platin and who show insufficient control of nausea/vomiting.

As recommended by most recent antiemetic guidelines, the optimal prophylaxis of chemotherapy-induced nausea and vomiting (CINV) requires the combination of 5-HT3 receptor antagonist (RA) with an NK1-RA. Moreover, the major predictors of acute and delayed CINV include: young age, female sex, platinum- or anthracycline-based chemotherapy, nondrinker status, emesis in the earlier cycles of chemotherapy, and previous history of motion/morning sickness. Despite improved knowledge of the pathophysiology of CINV and advances in the availability of active antiemetics, an inconsistent compliance with their use has been reported, thereby resulting in suboptimal control of CINV in several cases. In this scenario, a new anti-emetic drug is now available, which seems to be able to guarantee better prophylaxis of CINV and improvement of adherence to guidelines. In fact, netupitant/palonosetron (NEPA) is a ready-to-use single oral capsule, combining an NK1-RA (netupitant) and a 5-HT3-RA (palonosetron), which is to be taken 1 hour before the administration of chemotherapy, ensuring the coverage from CINV for 5 days. We reviewed the role of NEPA in patients at high risk of CINV receiving highly emetogenic chemotherapy. In these patients, NEPA plus dexamethasone, as compared to standard treatments, achieved superior efficacy in all primary and secondary end points during the acute, delayed, and overall phases, including nausea assessment. Moreover, these results were also achieved in female patients receiving anthracycline plus cyclophosphamide-based chemotherapy. NEPA represents a real step forward in the prophylaxis of CINV.

Chemotherapy-induced nausea and vomiting (CINV) is a significant clinical issue which affects patients' quality of life as well as treatment decisions. Significant improvements in the control of CINV have occurred in the past 15 years with the introduction of new antiemetic agents: 5-HT3 receptor antagonists, tachykinin NK1 receptor antagonists and olanzapine. Aprepitant was the first NK1 receptor antagonist introduced (2003) for the prevention of CINV in combination with a 5-HT3 receptor antagonist and dexamethasone. Two additional NK1 receptor antagonists, netupitant and rolapitant, were approved by the FDA in 2014 and 2015, respectively. A description of rolapitant and its role in CINV will be presented, along with a comparison to the other NK1 receptor antagonists, aprepitant and netupitant.

Among patients with cancer, chemotherapy-induced nausea and vomiting (CINV) is a common adverse effect that not only impacts quality of life, but also treatment outcomes. It is important to address these issues from both prevention and treatment standpoints so that patients remain adherent to their regimens. With CINV being classified into 5 different types, the primary medication options for prevention and treatment include 5-HT3 receptor antagonists, NK1 receptor antagonists, and corticosteroids. Other medications used, but to a lesser extent, include dopamine antagonists, benzodiazepines, cannabinoids, and olanzapine. In addition, those patients who express interest in alternative or nonpharmacologic therapies may have options as well. With the array of medications available for patients with cancer, pharmacists play an integral role in optimizing patient outcomes. Therefore, it is important that pharmacists stay up-to-date on the most current guidelines available for CINV treatment.
