Mechanism Of Action and Pharmacodynamic Effects
Palonosetron is an antagonist of the serotonin 5-HT3 receptor. Many chemotherapies cause the release of serotonin from the enterochromaffin cells of the small intestine. This neurotransmitter is then able to activate 5-HT3 receptors in the gut and on vagal afferents which activates the vomiting reflex. By inhibiting the activity of endogenous serotonin at these receptors, the drug reduces chemotherapy related nausea and vomiting [1].
