Nausea and vomiting continue to rank as important side effects for cancer patients receiving chemotherapy. The class of drugs known as the 5-HT3 receptor antagonists have become widely used for chemotherapy-induced nausea and vomiting, and are considered a standard part of care for moderately- and highly-emetogenic chemotherapy in combination with corticosteroids. Ondansetron (Zofran, Glaxo Wellcome), granisetron (Kytril, SmithKline Beecham) and dolasetron (Anzemet, Hoechst Marion Roussel) are commercially available in the US. Intravenous forms of all three drugs have demonstrated efficacy in preventing acute (< or = 24 h following chemotherapy) nausea and emesis due to moderately- and highly-emetogenic chemotherapy. Oral forms of the drugs have been shown to be effective in prevention of nausea and emesis due to moderately-emetogenic chemotherapy. More recently, oral 5-HT3 receptor antagonists have demonstrated efficacy in the prevention of nausea and vomiting due to highly-emetogenic chemotherapy as well. Comparative trials between the three agents have shown no clinically important differences in outcome and they should be considered clinically equivalent. Optimal oral anti-emetic regimens for high-dose chemotherapy with bone marrow or stem cell transplantation remain to be determined and future oral studies should target this population. In general, the decision of which 5-HT3 receptor antagonist to select for formulary inclusion should be based on the dose of anti-emetic used and the acquisition cost of the agents being compared. The oral route should be used whenever possible.

Recent years have witnessed significant improvements in the prevention and management of chemotherapy-induced nausea and vomiting (CINV), allowing patients to complete their prescribed chemotherapy regimens without compromising quality of life. This reduction in the incidence of CINV can be primarily attributed to the emergence of effective, well-tolerated antiemetic therapies, including serotonin (5-hydroxytryptamine or 5-HT3) receptor antagonists, neurokinin-1 (NK-1) receptor antagonists, and the atypical antipsychotic olanzapine. While 5-HT3 receptor antagonists are highly effective in the prevention of acute CINV, NK-1 receptor antagonists and olanzapine have demonstrated considerable activity against both acute and delayed CINV. Various combinations of these three types of agents, along with dexamethasone and dopamine receptor antagonists, are now becoming the standard of care for patients receiving moderately or highly emetogenic chemotherapy. Optimal use of these therapies requires careful assessment of the unique characteristics of each agent and currently available clinical trial data.
