Granisetron

Description

A serotonin receptor (5HT-3 selective) antagonist that has been used as an antiemetic and antinauseant for cancer chemotherapy patients. [PubChem]

Indication

For the prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer therapy (including high dose cisplatin), postoperation, and radiation (including total body irradiation and daily fractionated abdominal radiation).

Mechanism of Action

Granisetron is a potent, selective antagonist of 5-HT3 receptors. The antiemetic 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 inhibits the visceral afferent stimulation of the vomiting center, likely indirectly at the level of the area postrema, as well as through direct inhibition of serotonin activity within the area postrema and the chemoreceptor trigger zone.

Pharmacokinetics

Absorption
Absorption of is rapid and complete, though oral bioavailability is reduced to about 60% as a result of first pass metabolism.
Distribution
Metabolism
Primarily hepatic; undergoes N -demethylation and aromatic ring oxidation followed by conjugation. Animal studies suggest that some of the metabolites may have 5-HT 3 receptor antagonist activity.
