Prolonged administration of aprepitant improves cisplatin-based chemotherapy-induced nausea and vomiting.

Aims: To determine the antiemetic efficacy of a 6-day aprepitant schedule in patients receiving multiple-day cisplatin. Patients & methods: Patients diagnosed with lung cancer and who were chemotherapy-naive were screened. The patients willing to use aprepitant were randomly divided into two groups: prolonged use of aprepitant (PA; 6-day aprepitant) and standard use of aprepitant (SA; 3-day aprepitant); the patients who rejected aprepitant were recruited into the control group (group C). Primary end points included the safety and the number of days without chemotherapy-induced nausea and vomiting.

Results

There was no statistical difference in adverse events among the three groups. The average days without chemotherapy-induced nausea and vomiting of group PA (18.28 ± 3.35) was significantly longer than in groups SA and C. Furthermore, better life function scores were achieved in group PA according to the Functional Living Index - Emesis questionnaire.

Conclusion

In this study 6-day aprepitant was safe and more effective than standard 3-day aprepitant in controlling chemotherapy-induced nausea and vomiting due to 3-day cisplatin regimens.
