The clinical application of 5-HT3 receptor antagonists has enabled continuation of the course of chemotherapy including cisplatin, which induces strong nausea and vomiting, and to prevent the delay of curative treatment for cancer patients receiving neoadjuvant chemotherapy. However, with the development of basic research on the mechanisms of
vomiting
, each 5-HT3 receptor antagonist has appeared to have different pharmacological actions and, subsequently, the difference in the clinical efficacy of each drug has been reported in Europe and USA. In freshly advanced head and neck carcinoma cases, a randomised crossover study was performed to compare the efficacy and safety profile of a single intravenous dose for 7 days of azasetron (10 mg/day) or granisetron (3 mg/day) in the prophylaxis of nausea and vomiting induced by multi-drug chemotherapy including cisplatin (50 mg/m2 or 60 mg/m2). Anti-emetic effects were evaluated by the protective rates for nausea and vomiting for 7 days following the start of cisplatin administration. Both 5-HT3 receptor antagonists were highly effective in the prophylaxis of acute and delayed
emesis
induced by chemotherapy, whereas the efficacies of azasetron on day 3 and 4 were superior to those of granisetron.
No adverse effect
of either drug was observed in this study.

The inhibitory effects of GG032X tablets, a new dosage form (fast dispersing tablet) of ondansetron, 5-HT2 receptor antagonist, on nausea and
emesis
induced by cisplatin (CDDP), were investigated along with safety and usefulness. Subjects were chemotherapy patients starting CDDP administration for the first time, who were receiving a high single dose of CDDP (50 mg/m2 or more and intravenous drip infusion of less than 4 hours), or lower multiple doses of CDDP (a single dose of 10 mg/m2 or more, administered intravenously for 3-5 consecutive days). GG032X tablets were administered orally 1-2 hours before CDDP administration. In lower multiple doses of CDDP, GG032X tablets and CDDP were administered, as much as possible, at the same respective time when they were administered on the first day. Efficacy of GG032X tablets was evaluated in terms of inhibitory effect on nausea and
emesis
24 hours after administration of a high single dose of CDDP, and of the inhibitory effect on nausea and
emesis
during the study period (3-5 days) in lower multiple doses of CDDP. Efficacy, safety and usefulness were evaluated in accordance with the evaluation criteria used in the clinical study of already-approved ondanstron tablets. In a high single dose of CDDP, the cases judged "effective" or better in the investigation of the inhibitory effect of the drug on nausea and
emesis
, accounted for 52.9% (63/119 cases). As for the overall safety rating, the cases judged as "safe" accounted for 87.0% (107/123 cases), and as a "minor safety problem" accounted for 13.0% (16/123 cases). As for the usefulness rating, the cases judged "useful" or better accounted for 52.1% (62/119 cases). Major adverse effects included headache, fever, atrial fibrillation and increases in total bilirubin, GOT and GPT values. None of these was serious, and the patients recovered without any treatment or by nosotropic therapy. Meanwhile, in lower multiple doses of CDDP, the inhibitory effect judged "effective" or better accounted for 70.6% (12/17 cases). As for the overall safety rating, all cases were judged "safe". In terms of usefulness, those cases judged "useful" or better accounted for 70.6% (12/17 cases).
No adverse effect
was observed. Study results of these two groups were almost the same as those for already-approved ondansetron tablets. According to the results of questionnaires for the patients who participated in the study and took GG032X tablets, the drug was found to be easy to take and had favorable results. Based on the above results, GG032X tablets were evaluated as having the same inhibitory effect as the already-approved ondansetron tablets against CDDP-induced nausea and
emesis
, and were considered safe and clinically useful.

A randomized crossover study between azasetron alone and azasetron combined with dexamethasone was performed to investigate the prevention of nausea and vomiting due to chemotherapy including cisplatin in patients with advanced head and neck carcinoma. The results indicated that the combination therapy with dexamethasone was more effective than azasetron alone in preventing nausea on days 1 through 5 after the administration of cisplatin and was significantly superior to azasetron alone on days 2 and 3. In addition, complete response (no
vomiting
) and the antiemetic and antinausea efficacy of combination therapy with dexamethasone on day 2 was significantly superior compared to azasetron alone.
No adverse effect
from either antiemetic therapy was observed in this study.

Perioperative pain is still a major problem, and new pharmacological means should be explored to mitigate such pain. Adenosine is an ubiquitous endogenous substance; when exogenously administered, it provides a number of salutary effects including neuromodulation, antinociception, and cytoprotective actions. The aim of this study was to characterize the perioperative antinociceptive-analgesic effects of intraoperative adenosine infusion and determine the duration of actions in the postoperative period, and compare them to those of remifentanil in patients undergoing major surgical procedures in a double-blind study.Sixty-two patients were randomly assigned to one of the two treatments. After standard induction of anesthesia, the lungs were mechanically ventilated. Anesthesia was maintained with a constant alveolar concentration of inhaled anesthetics (3% desflurane and 65% nitrous oxide in oxygen). A variable-rate of intravenous infusion of adenosine (50-500 microg kg(-1) x min(-1)) or remifentanil (0.05-0.5 microg kg(-1) x min(-1)) was initiated 5 min before the skin incision and was titrated to maintain systolic blood pressure and heart rate within 20% of baseline values during surgery. Postoperative evaluations included the level of sedation, degree of pain severity, opioid analgesic (fentanyl, morphine) consumption, and cardiorespiratory variables for 48 h. Intraoperative inhibition of the cardiovascular responses to surgical stimulation could be equally achieved by adenosine or remifentanil, and both could maintain excellent hemodynamic stability. Postoperatively, however, there were striking differences: (1). initial pain score was reduced by 60% (P<0.001) in the adenosine group compared to the remifentanil group and it remained lower throughout the 48 h recovery period; (2). postoperative morphine requirements during the first 0.25, 2 and 48 h were consistently lower in the adenosine group as compared to the remifentanil group (78, 71 and 42%, P<0.001, respectively); (3). adenosine patients remained significantly less sedated at all evaluations; (4) the end-tidal and arterial carbon dioxide values in the remifentanil group were significantly higher when patients were admitted to the postanesthesia care unit.
No adverse effect
of adenosine was observed at any time. Intraoperative adenosine infusion provided a salutary recovery from anesthesia associated with a pronounced and sustained postoperative pain relief. Compared to remifentanil, adenosine significantly reduced the opioid requirements and minimized the side effects including protracted sedation, cardiorespiratory instability, nausea, and
vomiting
in the postoperative recovery period.

Recent investigations suggest the efficacy of olanzapine in cancer patients with intractable
vomiting
or chemotherapy-induced nausea. Olanzapine,indicated for schizophrenia in Japan, has an affinity for multiple neurotransmitter receptors including dopaminergic, serotonergic, histaminergic, adrenergic and muscarinic receptors. This pharmacological activity thus has a potential role in the treatment of nausea and vomiting. In the present study, olanzapine was given to five cancer patients with refractory
vomiting
to standard medications. In 3 cases, olanzapine resolved
vomiting
completely and also improved anorexia, In 2 cases,
vomiting
was controlled for a limited period.
No adverse effect
was observed. These results suggest olanzapine is a useful agent for the management of both
vomiting
and anorexia.
