Tropisetron

Product name:Tropisetron
CAS: 89565-68-4
Molecular Formula: C17H20N2O2
Molecular Weight: 284.35
Product description:Product is a peripheral and central nervous system neurons within 5 - HT3 receptor of selective inhibitors. Anticancer drugs or radiation can stimulate the intestinal mucosa chromaffin cells release 5 - HT3, induce the gag reflex, causing nausea and vomiting. This product selectivity in the reflection and weeks of the nervous system the excitement of presynaptic 5 - HT3 receptors, and May 5 - HT on the central nervous system. Receptor passed after the introduction of the vagus nerve area has a direct impact, this dual role in the process of blocking the gag reflex of chemical neurotransmitter, and vomiting caused by chemotherapy and radiotherapy has a therapeutic effect.
