Granisetron is a selective 5-HT3 receptor antagonist used primarily as an antiemetic to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and, to a lesser extent, postoperatively. It is an FDA-approved drug and is used clinically worldwide.
Pharmacokinetics
Pharmacokinetic parameters for healthy adult volunteers after oral administration of single 2 mg dose (film-coated tablet).
