Granisetron (HCl)

Granisetron is an oral and parenteral antiemetic agent. Granisetron (HCl) is commonly used to treat nausea and vomiting from highly emetogenic cancer chemotherapy. The actions, uses and adverse effects similar to those of ondansetron, but unlike ondansetron, Granisetron (HCl) is not approved for postoperative emesis. Granisetron selectively blocks type 3 serotonin (5-HT3) receptors. 5-HT3 receptors are found centrally in the chemoreceptor trigger zone and peripherally at vagal nerve terminals in the intestines. Whether the action of granisetron is mediated centrally, peripherally, or a combination of both remains to be determined.Granisetron injection was approved by the FDA on December 29, 1993. The oral dosage form was subsequently approved March 20, 1995 and has been shown to be as effective as IV ondansetron for chemotherapy-induced nausea and vomiting.
