The Correct Answer is AThe serotonin antagonists ondansetron and granisetron are the newest and among the most effective antiemetic agents. They selectively block the serotonin receptor 5-HT3, which is present peripherally on the vagus nerve and centrally in the chemoreceptor trigger zone. They are effective in the treatment of nausea and vomiting due to cisplatin but are without the dystonic reactions that may accompany metoclopramide.
