Granisetron is a new serotonin-receptor antagonist with considerable activity in preclinical models and early clinical studies against drug-induced nausea and vomiting. In a randomized, double-blind trial, two dose levels of granisetron were compared with regard to their efficacy and safety if given to patients receiving emetogenic chemotherapy with or without cisplatin. The present paper reports the Dutch experience with 125 patients included in this international trial. The two dose levels (40 and 160 micrograms/kg given once i.v. prior to chemotherapy) were equally effective in preventing acute emesis and nausea (within the first 24 h); in the group receiving cisplatin doses of 50 mg/m2 or more, 39% of patients had a complete response (no vomiting and mild nausea at most), with a complete response rate of 82% in the patients receiving moderately emetogenic chemotherapy. Sixty-three percent of patients receiving highly emetogenic chemotherapy with a complete response within 24 h lost this response during the next 6 days, as did 20% of the other patients. Headache was the most frequently reported adverse event (18%), followed by constipation (6%) and dizziness (4%). All adverse events were mild and occurred equally frequently at both dose levels. Granisetron at 40 micrograms/kg i.v. given once is effective in the prevention of acute chemotherapy-induced emesis and nausea, in particular in patients receiving moderately emetogenic therapy.

The aim of the present study was to assess the antiemetic efficacy of granisetron in repeated cycles of chemotherapy with platinum derivatives. The study included 50 patients (28 females, 22 males; aged 17-72, mean age 51 years). From 2 to 5 cycles of chemotherapy with cisplatin or carboplatin were performed. Granisetron was administered intravenously at a dose of 3 mg, 5 minutes before commencement of cytostatic chemotherapy. In case of 2 episodes of vomiting and severe nausea 2 additional doses of granisetron were given. Total control of emesis was achieved in 60% of patients after the first cycle of chemotherapy, and this percentage did not change significantly over the 5 cycles of chemotherapy. There were no differences in the antiemetic efficacy of granisetron in relation to patient sex up to cycle III, while in cycles IV and V a tendency towards less efficacy in females was observed. The adverse effects (headache, dizziness) were observed with the same frequency in the first 3 cycles of chemotherapy, while these were absent in cycles IV and V. Severe side effects were recorded only in cycle I, after that they were less expressed. In conclusion, granisetron is highly effective in prevention of emesis, induced by platinum derivatives and its efficacy is maintained over repeated cycles of chemotherapy. The toxicity of granisetron is mostly expressed in the first cycle, while after that it decreases significantly.

Objective This study was designed to compare the effectiveness of granisetron plus dexamethasone for preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery. Methods We searched the literature in the Cochrane Library, PubMed, EMBASE, and CNKI. Results In total, 11 randomized controlled trials were enrolled in this analysis. The meta-analysis showed that granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopy surgery. No significant differences in adverse reactions (dizziness and headache) were found in association with dexamethasone. Conclusion Granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopic surgery, with no difference in adverse reactions between the two groups. Granisetron alone or granisetron plus dexamethasone can be used to prevent PONV in patients undergoing laparoscopic surgery.
