Its high-purity chemical properties ensure the stability and consistency of pharmacological effects, while it also has favorable oral bioavailability, which can be quickly absorbed by the intestines and act on the central nervous system for a long time. Combined with 5-HT receptor antagonists and glucocorticoids, it forms a “triple antiemetic regimen”, greatly improving the quality of life of chemotherapy patients. This product is suitable for the prevention of nausea and vomiting in highly emetogenic chemotherapy regimens (such as cisplatin-based chemotherapy), and is a key auxiliary drug to improve patient tolerance in clinical tumor treatment. Meanwhile, it is also an excellent experimental sample for pharmaceutical companies to develop antiemetic drugs and scientific research institutions to explore neurotransmitter regulation mechanisms, meeting the dual needs of clinical treatment and scientific research.
