Preparation and Uses of Granisetron: it can be prepared by the reaction of 1-Methyl-1H-indazole-3-formyl chloride and 3-Amino-9-methyl-9-azabicyclo[3.3.1]nonane. Besides, this chemical is a serotonin 5-HT₃ receptor antagonist used as an antiemetic to treat nausea and vomiting following chemotherapy. Its main effect is to reduce the activity of the vagus nerve, which is a nerve that activates the vomiting center in the medulla oblongata. It does not have much effect on vomiting due to motion sickness and does not have any effect on dopamine receptors or muscarinic receptors.
