Real-world incidence of nausea and vomiting induced by antineoplastic agents: insights and future directions from the Japanese adverse drug event report database.

purposeAntineoplastic treatment commonly leads to nausea and vomiting (NV), which considerably affects the quality of life and adherence to therapy of patients. This study aimed to analyze the incidence of NV induced by antineoplastic agents using the Japanese Adverse Drug Event Report (JADER) database and to explore novel antiemetic therapies for oral antineoplastic agents.

methodsData from April 2004 to March 2023 were extracted from the JADER database. The analysis considered guideline-recommended antiemetics and involved the temporal evaluation of cases with NV. The onset patterns of NV were analyzed for each oral antineoplastic agent. The reported odds ratio was used to identify adjunctive medications that showed inverse associations with these symptoms.

resultsA large number of NV cases were reported for platinum compounds and irinotecan. Among the oral agents, a notable incidence of NV was induced by antimetabolites and tyrosine kinase inhibitors. A decreasing trend in the use of single-agent antiemetic therapy was observed from 2010. Distinct NV patterns were identified. Silodosin and meropenem emerged as potential adjunct therapies to suppress NV induced by oral agents.

conclusionAlthough there is a trend toward improvement in NV management with increased adherence to antiemetic therapies, a substantial gap remains between guidelines and actual practice. The need for tailored management strategies based on the onset patterns of NV for specific agents has been emphasized. Investigating the mechanisms underlying the antiemetic effects of adjunctive therapies, such as silodosin and meropenem, may pave the way for new antiemetic options for oral antineoplastic agents.
