Mechanism of Action of Granisetron

Granisetron is a potent, selective antagonist of 5-HT3 receptors. The antiemetic (effective against vomiting and nausea) activity of the drug is brought about through the inhibition of 5-HT3 receptors present both centrally (medullary chemoreceptor zone) and peripherally (GI tract). This inhibition of 5-HT3 receptors, in turn, blocks the substance serotonin, a natural substance in the body that causes nausea and vomiting.

Uses of Granisetron

Granisetron is indicated to prevent nausea and vomiting associated with initial and repeated courses of emetogenic (a substance that causes vomiting) chemotherapy and radiation therapy. It is also used to treat and prevent nausea and vomiting in adults that may occur after surgery.
