Fosaprepitant: current options to prevent chemotherapy-induced nausea and vomiting: A review

Abstract

Background. Chemotherapy (CT) is a mainstay of treatment for malignant tumors. CT-induced nausea and vomiting are observed in 3090% of patients within 0120 h after moderate and highly emetogenic CT administration. These adverse events can severely impact the quality of treatment, daily life, and adherence to treatment, thus reducing the effectiveness of therapy and survival.
 Materials and methods. The author provides the results of a systematic review of research papers, including clinical studies, on the efficacy of the neurokinin-1 receptor antagonist fosaprepitant to prevent CT-induced nausea and vomiting. Data from the PubMed database were reviewed.
 Results. The prevention and treatment of CT-associated nausea and vomiting are vital during special therapy, including symptomatic therapy. International organizations recommend using a triple combination with antagonists of neurokinin-1 and 5-hydroxytryptamine-3 receptors and dexamethasone. According to the data obtained, the efficacy of fosaprepitant has been proven in delayed and general phases in several large, well-planned studies; the drug reduces the incidence of adverse events by 2.74.4 times compared with aprepitant.
 Conclusion. Fosaprepitant is an antagonist of neurokinin-1 receptors; when administered intravenously, it rapidly converts into aprepitant. When used as part of a triple combination with 5-hydroxytryptamine-3 receptor antagonists and dexamethasone in patients receiving moderate and highly emetogenic CT leads to a higher rate of complete response when controlling nausea and vomiting. In general, fosaprepitant is well tolerated.
