What is Palonosetron HCl?

Palonosetron blocks the actions of chemicals in the body that may cause nausea and vomiting. Palonosetron is used to prevent nausea and vomiting associated with cancer chemotherapy. Palonosetron may also be used for purposes other than those listed in this medication guide.

How does Palonosetron HCl work?

Palonosetron is a selective serotonin subtype 3 (5-HT3) receptor antagonist with a strong binding affinity. 5-HT3 receptors are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema. Cancer chemotherapy is associated with nausea and vomiting when serotonin is released from the enterochromaffin cells of the small intestine activates 5-HT3 receptors located on vagal afferents and activates the vomiting reflex. Palonosetron may also block ion channels involved in ventricular polarization may prolong action potential duration. The effect of palonosetron on blood pressure, heart rate, and ECG parameters including QTc were comparable to ondansetron and dolasetron in clinical trials.
