The approved indications are: combined with other antiemetics, applicable to the prevention of chemotherapy-induced nausea and vomiting (CINV) during the initial and repeated treatment of highly vomiting anti-tumor chemotherapy.

Aprepitant is a neurokinin-1 (NK-1) receptor blocker. Its mechanism of action is to block the effect of substance P by binding to NK-1 receptor. Aprepitant can pass through the blood-brain barrier and occupy the NK-1 receptor in the brain and has high selectivity and affinity for NK-1 receptor. At the same time, aprepitant has a low affinity for NK-2 and NK-3 receptors, as well as for the targets of other drugs used to treat chemotherapy-induced nausea and vomiting symptoms (e.g. dopamine receptors and 5-HT receptor), making it more effective than other drugs in reducing nausea and vomiting. With its high safety, precise efficacy, and convenient administration, aprepitant has been unanimously recommended as a first-line drug and recommended drug for the prevention of nausea caused by highly vomiting anti-tumor chemotherapy by European and American authoritative guidelines such as the National Comprehensive Cancer Network Clinical Use Guidelines.

Aprepitant is clinically well positioned and widely used as a new generation drug for the prevention of nausea and vomiting caused by chemotherapy in oncology, and will have a very broad application prospect.
