These agents are an option for treating emesis associated with BPV.Ondansetron selective 5-HT3 receptor antagonist binds to 5-HT3 receptors both in periphery and in CNS, with primary effects in GI tract. The 5-HT3 antagonists, informally known as "setrons", are a class of drugs that act as receptor antagonists at the 5-HT3 receptor, a subtype of serotonin receptor found in terminals of the vagus nerve and in certain areas of the brain. Selective 5-HT3-receptor antagonists antiemetic properties are mediated through central (vomiting center, chemoreceptor trigger zone) and peripheral (intestinal and spinal) 5-HT3 receptor blockade.
