ANTEMETIC ONDANSETRON HCL
CAS NO 146475-23-2/146844-89-5
MF: C17H19F2N3O3
Standard: BP/EP/USP
ASSAY 98~102%
White or almost white crystalline powder
Slightly soluble in water, very slightly soluble in methanol, practically insoluble in ethano
USE:
Ondansetron hcl is a serotonin 5-HT3 receptor antagonist used mainly as an antiemetic, often following chemotherapy. It affects both peripheral and central nerves. Ondansetron reduces the activity of the vagus nerve, which deactivates the vomiting center in the medulla oblongata, and also blocks serotonin receptors in the chemoreceptor trigger zone. It has little effect on vomiting caused by motion sickness, and does not have any effect on dopamine receptors or muscarinic receptors.
