The efficacies of granisetron plus dexamethasone and granisetron alone in controlling nausea and vomiting during two consecutive cycles of moderately emetogenic chemotherapy given for up to 5 days were compared in a two-centre, randomised, double-blind, placebo-controlled crossover study. In all, 110 evaluable patients received either dexamethasone, 20 mg i.v., or matching placebo, plus open-label granisetron, 3 mg i.v., given on each chemotherapy day. At cycle 2, patients crossed over to the alternative treatment; 72 patients completed the crossover. In these 72 patients, the complete response rates over 24 h for granisetron plus dexamethasone and granisetron plus placebo in cycle 1 were 87% and 70% (ns), respectively. In cycle 2 the complete response rates over 24 h were 73% and 62% (ns). Combining the two cycles, the complete response rates over 24 h were 80.6% (granisetron plus dexamethasone) and 65.3% (granisetron plus placebo; P = 0.015). Granisetron plus dexamethasone was significantly more effective in terms of times to less than complete response (P = 0.041), to first episode of moderate/severe nausea (P = 0.04), to first episode of vomiting (0.03) and to use of rescue medication (P = 0.02). Adverse events tended to be minor, with asthenia and insomnia the most common. Of those patients who expressed a preference, 67% preferred granisetron plus dexamethasone (P < 0.05). A single dose of dexamethasone added to granisetron thus enhances the efficacy of granisetron alone in preventing nausea and vomiting after moderately emetogenic chemotherapy.

The safety and efficacy of granisetron (10 micrograms/kg and 40 micrograms/kg) were evaluated during a second (n = 393) and third (n = 200) cycle of chemotherapy in this multicenter, double-blind, randomized, parallel-group study. Granisetron was administered as a single intravenous dose before the start of cisplatin chemotherapy (> or = 60 mg/m2). Total control (no vomiting, no retching, no nausea, and no use of antiemetic rescue medication) after the first 24 hr following chemotherapy was achieved in 40% and 49% of patients in Cycles 2 and 3, respectively, for the 10 micrograms/kg group, and in 42% and 38% of patients in Cycles 2 and 3, respectively, for the 40 micrograms/kg group. Both dose levels of granisetron were well tolerated. The results demonstrate comparable efficacy between the 10 micrograms/kg and 40 micrograms/kg doses of granisetron in preventing nausea and vomiting during repeat cycles of high-dose cisplatin-based chemotherapy. The results of this study show that granisetron 10 micrograms/kg is safe and well tolerated, and remains effective with repeat cycle use.

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.

Granisetron (G) is an effective antiemetic drug that is used to prevent cisplatin-induced emesis, although it is less effective for delayed emesis. To enhance the antiemetic effects of granisetron, corticosteroid analogues such as methylprednisolone (M) and dexamethasone (D) were employed in a study of patients treated with cisplatin (CDDP). We investigated the clinical response and urinary excretion of 5-hydroxyindole acetic acid (5-HIAA), the main metabolite of serotonin, in 31 patients with ovarian cancer or uterine endometrial cancer who received CAP therapy (CDDP 75 mg/m2) in a 3-day cross-over trial comparing G + M and G + D treated patients. Both regimens were and delayed emesis than G + D. We conclude that G + D is a more efficacious combination than G + D in protecting patients from CDDP-induced acute and delayed emesis.

This double-blind, double-dummy, randomized study compared the 24 h efficacy and safety of granisetron alone (3 mg i.v. over 30 s) or in combination with methylprednisolone (250 mg i.v. twice daily) in preventing nausea and vomiting in 308 patients (254 males) receiving high-dose cisplatin (100 mg/m2 or above) for mainly lung, and head and neck cancers. All patients received oral follow-on therapy comprising oral granisetron and methylprednisolone during the following 6 days. Primary efficacy variables were the proportions of complete responses (CR; no vomiting, no worse than mild nausea, no rescue and no withdrawal), no vomiting and no nausea over the first 24 h following initiation of the cisplatin infusion. The two treatment groups were well matched for demographics, cancer site, cisplatin dose and duration of infusion. Granisetron plus methylprednisolone was significantly more effective than granisetron alone for all primary efficacy variables: CR 78 versus 59% (p<0.001), no vomiting 80 versus 61% (p<0.001) and no nausea 74 versus 57% (p<0.002). Significantly more patients receiving the combination were free of any emetic symptoms (74 versus 54%, p<0.001). Significantly fewer patients receiving combination therapy also required rescue therapy with i.v. granisetron (12.2 versus 21.7%, p=0.026). During the follow-on period, complete response rates varied day by day from 50 to 71%. Both treatments were well tolerated, with constipation, abdominal pain and headache as the most frequent adverse events.

1. Granisetron and its combination with dexamethasone for the treatment of delayed emesis following cisplatin (CDDP) administration were investigated using ferrets. 2. CDDP-induced emesis was significantly inhibited in both the granisetron group and the combined granisetron and dexamethasone group during the acute and delayed phase in terms of total emesis, latency to first emesis and duration of emesis. 3. Food and water consumption in the combined group of ferrets was significantly increased as compared with the CDDP control group. 4. 5-Hydroxytryptamine (5-HT) level was increased in the ileum and the 5-hydroxyindole acetic acid (5-HIAA) level was increased in the area postrema of ferrets after 3 days of CDDP administration. It is suggested that the antiemetic activity of granisetron and/or dexamethasone is not related to 5-HT levels in delayed emesis. 5. Both granisetron and its combination with dexamethasone are effective in CDDP-induced emesis, but combination treatment is more effective than granisetron alone for the duration of emesis in the delayed phase.

Recently, Granisetron (KYT) was proved to have a strong effect for cisplatin (CDDP)-induced emesis. We compared the effect of KYT for CDDP-induced emesis between two different administration schedules. Forty micrograms/kg of KYT was administered either by 30-minute drip infusion with 100 ml of saline (Group A) or 30-second injection with 10 ml of saline (Group B). We investigated the therapeutic effect of KYT in both group A and Group B by the crossing-over method. After the patients who had a malignant tumor and were going to receive CDDP (over 50 mg/m2) in two courses were selected, KYT was administered by the method of Group A or Group B in a double-blind comparison. The clinical efficacy was at least "effective" in 70% (7/10) of Group A and Group B. The study treatment was considered "useful" in 80% (8/10) of Group A, 90% (9/10) of Group B, and "safe" in 100% of Group A and B. There was no difference between two groups in this respect. The results showed that the slow intravenous injection of KYT also has an excellent antiemetic effect on CDDP-induced emesis and a high degree of safety.

The efficacy of granisetron hydrochloride 20 microg/kg and 40 microg/kg were compared using a cross-over method to determine the optimal dose in children with solid tumors receiving high-dose chemotherapy. Granisetron controlled the onset of vomiting in 17 of 23 patients (73.9%) who were given 40 microg/kg of granisetron, while 8 of 21 patients (38.1%) were free of vomiting in the 20 microg/kg group. The average frequency of vomiting was 7.22 times in the 20 microg/kg dose versus 4.44 times in the 40 microg/kg dose. No safety problems were associated with either dose. The 40 microg/kg dose of granisetron appears to be more optimal.

The antiemetic effect of granisetron, a selective 5-HT3 receptor antagonist, on ouabain-induced emesis was studied using ferrets. In order to clarify the relationship between ouabain-induced emesis and serotonin (5-HT), we examined its effects on 5-HT release from the isolated ileum. Afferent vagal nerve activity was also determined. An intravenous bolus injection of ouabain (0.1-1.0 mg/kg) produced emesis in a dose-dependent manner. Ouabain-induced emesis was inhibited by pretreatment with granisetron. In the isolated ileum, ouabain induced a concentration-dependent increase of 5-HT. This release of 5-HT was suppressed by granisetron. Increases in vagal nerve discharges were observed immediately after the intravenous administration of ouabain (0.1-1.0 mg/kg). These increases were suppressed by granisetron. Taken together, ouabain activates 5-HT release from the mucosa in the gastrointestinal tract. Released 5-HT may activate the vagal afferent nerves, resulting in vomiting. Granisetron inhibited the ouabain-induced elevation of 5-HT and vagal nerve activity. Ouabain may induce emesis as well as negative chronotropic effects by activating the vagus. Our results suggest that ouabain-induced emesis is in part mediated by the 5-HT3 receptors of the peripheral gastrointestinal tract.

The prevention of nausea, vomiting and appetite loss induced by remission induction chemotherapy for acute myeloid leukemia was compared by randomization between granisetron alone and combination with granisetron plus methylprednisolone. Granisetron was administered at 40 micrograms/kg during chemotherapy, and methylprednisolone was administered concomitantly at 125 mg/body for 3 days or more in the combination group. The single and combination groups comprised 14 and 13 patients, respectively, and there was no significant difference between the background of both groups. To evaluate the effect they were scored according to 4 grades, and evaluated every 24 hours from the start of chemotherapy to 5 days after its completion. The complete inhibition rate of vomiting was as high as 71.4% and 92.3% in the single and combination groups, respectively, showing no significant difference. The grade of vomiting was mild in both groups. Nausea was noted in 71.4% and 46.2%, respectively, and the inhibitory effect tended to be higher in the combination group. Appetite loss developed in 92.9% and 41.7%, respectively, and the prevention effect was clearly higher in the combination group. The prevention effects on nausea 7, 8 and 10 days after the start of chemotherapy, on appetite loss 2-10 days after it, and 2-5 days after its completion, were higher in the combination group. Granisetron revealed an excellent inhibitory effect on vomiting induced by remission induction chemotherapy for acute myeloid leukemia, but combination with granisetron and methylprednisolone was considered useful for nausea in the latter half of the treatment period and for appetite loss during the whole period.
