[Antiemetics and its clinical evaluations].
Nausea and vomiting induced by anticancer agents are common problems associated with chemotherapy for cancer. Recent trials have examined a variety of antiemetics, representing several different classes of drugs. High dose metoclopramide provided the impetus for many of the current studies because of its effect against cisplatin induced vomiting. However, current regimens are not yet entirely effective in many patients receiving cisplatin or other highly emetogenic anticancer agents. A promising new class of antiemetics, 5-hydroxytryptamine receptor antagonists are undergoing clinical evaluations. Members of this class are easily and safely administered to patients receiving cisplatin or other emetogenic anticancer agents. These are highly active antiemetics, both prophylactic and interventional treatment. Lack of extrapyramidal reaction and other adverse effects associated with its use makes the drug a very attractive one. However, studies of antiemetics require consideration of methodologic issues that may not be of concern in trials of anticancer agents. The results of these studies can be affected by the patient population, the sample size, pharmacologic variables, the trial design, the method of analysis, etc. Recently, developments both in new-antiemetics and better ways of using the existing ones, lead us to cautious thought that nausea and vomiting due to cancer chemotherapy can be controlled substantially with benefit to the patients.
