WebOndansetron is a selective 5-hydroxytryptamine(3) (5-HT(3)) receptor antagonist that has been introduced to clinical practice as an antiemetic for cancer treatment-induced and anesthesia-related nausea and vomiting. Its use under these circumstances is both prophylactic and therapeutic. WebPalonosetron is highly selective for 5-HT 3 R and possesses greater affinity, a longer plasma half-life, and improved efficacy in preventing chemotherapy-induced nausea and vomiting compared with first-generation setrons ( Rojas et al., 2010; Thompson, 2013 ). A detailed list of competitive antagonists is shown in Table 1.
