Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial[Examination of anti-emetic effect, safety and usefulness of single oral dose of ondansetron tablet in nausea and emesis induced by anti-cancer drugs--dose-finding study of ondansetron tablet in patients receiving non-platinum anti-cancer drugs].
Inhibitory effects on acute nausea and emesis, safety and usefulness of a single oral dose of Ondansetron tablet were evaluated in 3 different dose levels for comparison by telephone registration system, in patients receiving non-platinum anti-cancer drugs. A single dose of ondansetron at 4 mg, 8 mg or 12 mg was given orally at 2 hrs before the initial administration of anti-cancer drugs. The patients were observed for 24 hours after administration of anti-cancer drugs, for occurrence of nausea and emesis. ⋯ Side effects were observed in 3 cases (headache, cold feeling and trembling in limbs, sleepiness) in 12 mg dose group, but these symptoms were not severe and disappeared after several hours or several days. No abnormality in clinical laboratory findings attributable to Ondansetron was observed. From the above, it was considered that Ondansetron was a clinically useful anti-emetic for nausea and emesis induced by non-platinum anti-cancer drugs and that 4 mg once daily was the optimal dose.

Randomized Controlled Trial Clinical Trial[Anti-emetic effect of ondansetron in cisplatin induced nausea and vomiting--a randomized clinical trial].
The anti-emetic effect of ondansetron in cisplatin induced nausea and vomiting was studied in a randomized cross-over trial in 52 patients. The dose of cisplatin was 80-120 mg/M2 iv drip given in 1-3 days. The patients randomly received ondansetron or our routine anti-emetic regimen in the first cycle of chemotherapy. ⋯ The mean frequency of vomiting were 1.3 times in ondansetron and 8.0 times in the routine regimen (P less than 0.01). Control of delayed emesis was comparable in the two arms. No patient had neurological symptoms in the ondansetron group whereas 4 patients in the routine group had extrapyramidal symptoms.

Randomized Controlled Trial Multicenter Study Clinical TrialOndansetron is effective in decreasing postoperative nausea and vomiting.
The efficacy of ondansetron, a selective 5-HT3 receptor antagonist, in preventing postoperative nausea and vomiting in surgical patients was studied. Fifty women were randomized in a double-blind manner to receive either two 8 mg doses of intravenous ondansetron or two doses of placebo vehicle: the first given just before general anesthesia induction and the second 8 hours later. During the first 24 postoperative hours, the number of emetic episodes was recorded and the subjects rated their nausea on a scale from 0 to 10. ⋯ The number of complete responders (no emetic episodes and no rescue therapy) was 1 of 24 (4%) and 15 of 26 (58%) in the placebo and ondansetron groups, respectively (p less than 0.001). Ondansetron is clearly more effective than placebo in the prophylaxis of postoperative nausea and vomiting. The adverse event profile for ondansetron was similar to that of placebo.

Randomized Controlled Trial Clinical TrialThe antiemetic efficacy and safety of prophylactic metoclopramide for elective cesarean delivery during spinal anesthesia.
The efficacy and safety of intravenous metoclopramide administered prophylactically before elective cesarean delivery under spinal anesthesia was studied. ⋯ Metoclopramide administered before induction of spinal anesthesia for cesarean delivery appears to significantly reduce both pre- and postdelivery emetic symptoms without apparent adverse effects on mother or neonate.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Efficacy of orally administered ondansetron in the prevention of postoperative nausea and vomiting: a dose ranging study.
In a placebo-controlled, double-blind study, we have compared the efficacy of ondansetron 16 mg, 8 mg and 1 mg administered 8-hourly for prevention of postoperative nausea and vomiting. We studied 995 patients undergoing major gynaecological surgery; 982 were included in the analysis. ⋯ The frequency of nausea was 75%, 70%, 56% and 55% after placebo and ondansetron 1 mg, 8 mg and 16 mg, respectively; the corresponding frequencies of vomiting were 60%, 55%, 37% and 37%. Ondansetron 8 mg was as effective as 16 mg and both resulted in significant reductions in nausea and vomiting compared with placebo and ondansetron 1 mg (P less than 0.001).
