Description

technical field [0001] The invention relates to a palonosetron hydrochloride injection and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] The chemical name of Palonosetron Hydrochloride is 2-[1-azabicyclo(2.2.2)oct-3S-yl]-2,3,3aS,4,5,6-hexahydro-1H-benzene And[de]isoquinolin-1-one hydrochloride, molecular formula: C 19 h 24 N 2 O·HCl, molecular weight 332.87. [0003] [0004] Palonosetron hydrochloride was originally developed by the Swiss Helsinn company. It is a new 5-HT3 receptor antagonist developed after ondansetron, granisetron, tropisetron, etc. It binds to 5-HT3 receptors The activity is dozens to hundreds of times stronger than other varieties, with high curative effect, low dosage (0.25mg / day), long half-life in vivo (more than 40 hours), single dose (0.25mg / day) curative effect can reach 5 days, and side effects are relatively low It is characterized by less pain (mainly headache) and can...
