BACKGROUND: Intravenous antiemetic combinations containing a 5-HT3 receptor antagonist (like metoclopramide, ondansetron, or granisetron) with dexamethasone have become the standard therapy for the treatment of acute chemotherapy-induced vomiting. Intravenous antiemetics, however, can be more costly and take more time to prepare and deliver, and therefore are not preferred for home, outpatient, or office use. The objective of this study was to determine the antiemetic activity and safety of the oral combination antiemetic regimen of metoclopramide, dexamethasone, and diphenhydramine in patients with small cell lung cancer receiving standard outpatient chemotherapy programs. METHODS: Fifty-two patients receiving initial cisplatin (60 mg/m2) or cyclophosphamide (600-1500 mg/m2) plus doxorubicin (30-45 mg/m2) received an oral regimen of metoclopramide (3 mg/kg x 2 then 2 mg/kg x 2 or 4 doses), dexamethasone (20 mg) and diphenhydramine (50 mg x 2 or 3 doses) (oral MDD), beginning 30 minutes before chemotherapy. RESULTS: Vomiting was prevented in 15 of 21 (76%) patients (95% confidence interval [CI], 53%-92%) receiving cisplatin and 21 of 31 (71%) individuals (95% CI, 52%-86%) given cyclophosphamide plus doxorubicin. Adverse effects were mild and transient and included sedation, loose stools, akathisia, and hiccoughs. CONCLUSIONS: The oral MDD antiemetic regimen prevented acute emesis in 73% of the patients entered and was well tolerated in this population of patients with small cell lung cancer. 相似文献

This study compared the efficacy and tolerability of oral ondansetron (8 mg twice daily [BID] for up to 3 days) with those of phenothiazine prochlorperazine (10 mg BID for up to 3 days) in 133 cancer patients receiving cyclophosphamide-based chemotherapy. In addition, the study evaluated the impact of these treatments on patients' health-related quality of life, measured with both the Functional Living Index--Cancer and the Functional Living Index--Emesis questionnaires. The first dose of study drug was administered 30 minutes before initiation of chemotherapy. Patients received a rescue antiemetic at their request or if the investigator deemed it necessary. There was a statistically significant difference in the number of patients with no emetic episodes over the 3-day study period: 60% in the ondansetron group compared with 21% in the prochlorperazine group. Twenty-five percent of ondansetron-treated patients compared with 68% of prochlorperazine-treated patients experienced three or more emetic episodes, rescue medication use, or withdrawal from the study due to adverse events or lack of efficacy of the study drug. Among patients with at least one emetic episode, the mean time to emesis was significantly longer (13 hours and 37 minutes) in the ondansetron group compared with the prochlorperazine group (9 hours and 30 minutes). Nausea and appetite scores did not differ significantly between groups. The score on the vomiting subscale of the Functional Living Index--Emesis was significantly more favorable in the ondansetron group compared with the prochlorperazine group, indicating better maintenance of health-related quality of life in ondansetron-treated patients. Both treatments were well tolerated. The most common potentially drug-related adverse event was headache, which occurred in significantly more (16%) ondansetron-treated patients compared with prochlorperazine-treated patients (3%). The results of this study demonstrate that oral ondansetron 8 mg BID for up to 3 days is more effective than prochlorperazine 10 mg BID for up to 3 days in the prevention of emesis associated with moderately emetogenic chemotherapy. 相似文献

PURPOSE: The antiemetic effectiveness and safety of single-dose oral granisetron were compared with intravenous (I.V.) ondansetron in chemotherapy-naive patients who received moderately emetogenic chemotherapy. PATIENTS AND METHODS: In this double-blind, parallel-group study, patients naive to emetogenic chemotherapy (N = 1,085) who were scheduled to receive cyclophosphamide- (500 to 1,200 mg/m2) or carboplatin (> or = 300 mg/m2) based chemotherapy, were randomized to receive either oral granisetron (n = 542) or I.V. ondansetron (n = 543). Efficacy assessments included the proportion of patients in each treatment group with total control over the 24 and 48 hours following chemotherapy initiation, as well as incidence and severity of nausea and emesis and use of antiemetic rescue medication. Prophylactic corticosteroids were allowed. Safety assessment was based on patients' reports of adverse experiences. RESULTS: Approximately 80% of patients received prophylactic corticosteroids. Single-dose oral granisetron (2 mg) and I.V. ondansetron (32 mg) resulted in equivalent levels of total emetic control during the first 48 hours after chemotherapy. The proportion of nausea- and emesis-free patients at 24 and 48 hours were also approximately equivalent. The most commonly reported adverse experiences were headache, asthenia, and constipation. More patients who received ondonsetron than granisetron reported dizziness (9.6% v 5.4%, respectively; P = .011) and abnormal vision (4.2% v 0.6%, respectively; P < .001). CONCLUSION: A single oral dose of granisetron (2 mg) resulted in equivalent levels of antiemetic protection as I.V. ondansetron (32 mg). Both agents were well tolerated, although more dizziness and abnormal vision were reported with ondansetron. Because the two antiemetic regimens exhibited equivalent efficacies, additional factors such as convenience and cost of therapy should be considered. 相似文献

PURPOSE: To evaluate the antiemetic efficacy and safety of adding the dopamine antagonist prochlorperazine to the combination of granisetron and dexamethasone in the prevention of acute nausea and vomiting following high-dose cisplatin. PATIENTS AND METHODS: Sixty patients receiving cisplatin (> or = 75 mg/m2) (median dose = 100 mg/m2) were enrolled at three sites. Patients received prochlorperazine spansule 15 mg orally, 60 minutes prior to and 12 hours after cisplatin; dexamethasone 20 mg intravenously, 45 minutes prior to cisplatin, and 10 mg intravenously or orally, 12 hours after cisplatin; and granisetron 10 micrograms/kg intravenously, 30 minutes prior to cisplatin. Efficacy was assessed during the 24-hour period after cisplatin using complete antiemetic response (no emetic episodes and no rescue antiemetics) and patient assessment of nausea and satisfaction using 100-mm visual analog scales (nausea: 0 = none, 100 = nausea as bad as it can be; satisfaction: 0 = not at all satisfied, 100 = satisfied as can be). RESULTS: Complete response (0 emetic episodes) was noted in 84% (49/58) of patients. Forty-two patients (72%) experienced no nausea. The mean change in posttreatment nausea visual analog scales from baseline was 8.9 mm. Forty-eight patients (83%) were completely satisfied with their antiemetic treatment. The mean posttreatment patient satisfaction score was 92 mm. Treatment was well tolerated, with infrequent and minor adverse events. CONCLUSIONS: This three-drug antiemetic regimen is well tolerated and highly effective in the prevention of acute nausea and vomiting arising from high-dose cisplatin. Further studies evaluating this regimen are warranted. 相似文献

We have reported previously that the anti-emetic efficacy of single agent 5HT3 antagonists is not maintained when analysed with the measurement of cumulative probabilities. Presently, the most effective anti-emetic regimen is a combination of a 5HT3 antagonist plus dexamethasone. We, therefore, assessed the sustainment of efficacy of such a combination in 125 patients, scheduled to receive cisplatin > or = 70 mg m(-2) either alone or in combination with other cytotoxic drugs. Anti-emetic therapy was initiated with 10 mg of dexamethasone and 3 mg of granisetron intravenously, before cisplatin. On days 1-6, patients received 8 mg of dexamethasone and 1 mg of granisetron twice daily by oral administration. Protection was assessed during all cycles and calculated based on cumulative probability analyses using the method of Kaplan-Meier and a model for transitional probabilities. Irrespective of the type of analysis used, the anti-emetic efficacy of granisetron/dexamethasone decreased over cycles. The initial complete acute emesis protection rate of 66% decreased to 30% according to the method of Kaplan-Meier and to 39% using the model for transitional probabilities. For delayed emesis, the initial complete protection rate of 52% decreased to 21% (Kaplan-Meier) and to 43% (transitional probabilities). In addition, we observed that protection failure in the delayed emesis period adversely influenced the acute emesis protection in the next cycle. We conclude that the anti-emetic efficacy of a 5HT3 antagonist plus dexamethasone is not maintained over multiple cycles of highly emetogenic chemotherapy, and that the acute emesis protection is adversely influenced by protection failure in the delayed emesis phase. 相似文献

OBJECTIVE: To evaluate the antiemetic efficacy of a modified regimen of oral ondansetron and dexamethasone in patients with lupus nephritis undergoing treatment with cyclophosphamide whose conventional antiemetic regimen had failed. DESIGN: A before-after prospective observational pilot project. SETTING: A federal research hospital. PATIENTS: Fourteen outpatients with lupus nephritis receiving intravenous cyclophosphamide 0.75-1.0 g/m2 had previously experienced chemotherapy-induced emetic events (vomiting or retching) while receiving a standard combination intravenous antiemetic regimen. The regimen consisted of four doses of thiethylperazine 10 mg and diphenhydramine 25 mg every 6 hours, and two doses of lorazepam 0.5 mg every 6 hours starting at 1 hour prior to cyclophosphamide. A subset of 8 patients previously completed a blinded study in which they received the intravenous formulation of ondansetron (4 doses of 4-16 mg q4h) administered orally beginning 30 minutes prior to the cyclophosphamide infusion. MAIN OUTCOME MEASURES: The number of emetic events and cost of drug administration were assessed for the modified ondansetron intervention and compared with those of the standard antiemetic regimen. The incidence of emetic events and visual analog nausea scores for the subset of eight patients were also evaluated. INTERVENTIONS: To account for the delayed onset of emesis associated with cyclophosphamide, patients received both ondansetron 8 mg orally every 4 hours (3 doses) and dexamethasone 10 mg orally (1 dose) beginning 4 hours after the cyclophosphamide infusion. This is different from the manufacturer's recommended dose schedule, in which ondansetron is administered prior to chemotherapy. RESULTS: No emetic events were observed following the administration of oral ondansetron/dexamethasone. The 95% confidence interval for the true rate of emesis was 0% to 19.3%. There was a significant difference in efficacy between ondansetron/dexamethasone and the triple antiemetic regimen (p < 0.0002). None of the patients experienced adverse effects while receiving the ondansetron/dexamethasone regimen. Cost comparisons (including admixture and nursing administration times) for standard combination therapy and oral ondansetron/dexamethasone were $109.09 and $70.24, respectively. No difference in emetic events or nausea ratings was observed between oral ondansetron/dexamethasone tablets and oral administration of ondansetron using the intravenous formula. CONCLUSIONS: This study suggests that a modified oral ondansetron/dexamethasone regimen is safe and efficacious, and costs less than alternative regimens to prevent cyclophosphamide-induced emesis in patients with lupus nephritis. 相似文献

Granisetron, a potent and selective 5-hydroxytryptamine receptor (5-HT3) antagonist was reported to be an effective antiemetic agent both in animal studies and in patients given highly emetogenic chemotherapy. A sample of 43 patients with breast cancer was accrued from September to November 1992 in a phase II study to assess the efficacy of granisetron in patients receiving FEC (5-FU, epirubicin, cyclophosphamide). Each patient received 3 mg intravenous granisetron as a single dose just prior to chemotherapy. Oral metoclopromide was prescribed to each patient as a rescue anti-emetic. The emetic episodes and degree of nausea were evaluated on a daily basis. Good control of emesis (0-2 episodes of vomiting) and nausea (mild or no nausea) was in the range 77%-98% and 77%-93% respectively. There was a complete response (no emetic episodes throughout the 6-day period) in 16 patients (37.2%). Onset of emesis tends to occur on day 1 and tend to subside after day 3; 85% of patients had onset of emesis in the first 2 days after chemotherapy. Control of emesis and nausea tends to improve after day 3, which could be the result of the reduced emetogenicity of the combination FEC with time. Altogether, 77% had good control of acute emesis; control of delayed emesis was better with 84% achieving a major response on day 2 after chemotherapy, which improved to more than 90% after day 4. Granisetron was generally tolerated with headache being the most common side-effect followed by constipation and flushing. This study suggests that granisetron is an effective and well-tolerated anti-emetic agent, which deserves randomised trials to elucidate its efficacy further. 相似文献

We conducted this study to compare granisetron, 5-HT3 antagonist, with conventional antiemetics in the prophylaxis of emesis induced by conditioning chemotherapy for allogeneic bone marrow transplantation in 41 patients. The conditioning chemotherapy regimen included either cytosine arabinoside 2 g/m2 x 4 and cyclophosphamide 60 mg/kg x 2 (CA, CY), or busulfan 4 mg/kg x 4 and cyclophosphamide 60 mg/kg x 2 (BU, CY). In CA and CY regimen, the clinical effective rate with granisetron against emesis was 94.1% on the 1st day, compared with 7.6% in the control group. On day 2 and 3, the effective rate with granisetron was 58.8% and 23.5%, respectively, compared with 0% in the control group. In the BU and CY regimen, control of emesis with granisetron on day 5 and 6 was 66.7%, against 20.0% in the control group. Based on these data, we concluded granisetron is superior to conventional antiemetics in the prophylaxis of emesis induced by conditioning for allogeneic bone marrow transplantation. 相似文献

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. 相似文献

BACKGROUND: Dexamethasone decreases chemotherapy-induced emesis when added to an antiemetic regimen. This study was undertaken to evaluate the efficacy of granisetron-dexamethasone combination for the prevention of postoperative nausea and vomiting (PONV) in female patients undergoing general anaesthesia for breast surgery. METHODS: In a randomized, double-blind manner, 135 ASA I patients, aged 40-65 years, were assigned to receive placebo (saline), granisetron 40 micrograms.kg-1 or granisetron 40 micrograms.kg-1 plus dexamethasone 8 mg i.v. (n = 45 of each) immediately before the induction of anaesthesia. A standard general anaesthetic technique and postoperative analgesia were used. The PONV and safety assessments were performed continuously during the first 3 h (0-3 h) and the next 21 h (3-24 h) after anaesthesia. RESULTS: A complete response, defined as no PONV and no administration of rescue antiemetic medication, during 0-3 h after anaesthesia was 51%, 82% and 96% in patients who had received placebo, granisetron and granisetron-dexamethasone combination, respectively; the corresponding incidence during 3-24 h after anaesthesia was 56%, 84% and 98% (P < 0.05; overall Fisher's exact probability test). No clinically important adverse events were observed in any of the groups. CONCLUSION: Prophylactic use of granisetron-dexamethasone combination is more effective than granisetron alone for the prevention of PONV after breast surgery. 相似文献

This review discusses the development and use of 5-hydroxytryptamine3 (5-HT3) antagonists, especially granisetron, for the treatment of chemotherapy-induced emesis. Following recent evidence suggesting that high-dose chemotherapy is more effective in increasing tumor response rate and median survival time, more effective antiemetic control is essential. Granisetron, a new 5-HT3, is approximately 400 times more potent than metoclopramide and, unlike metoclopramide, does not produce extrapyramidal side effects. Granisetron has been shown to be effective as a single prophylactic dose, over 5 days and in patients receiving repeated cycles of chemotherapy. Patients with nausea and vomiting within the first 24 h after chemotherapy are more likely to experience delayed symptoms; however, episodes of breakthrough nausea and vomiting can be controlled by intervention with one, and in some cases more, doses of granisetron. The development of granisetron represents an important advance in the control of chemotherapy induced emesis. 相似文献

PURPOSE: This analysis was undertaken to review published reports of the comparative efficacy and safety of 5-hydroxytryptamine-3 (5-HT3) receptor antagonists in the prophylaxis of acute chemotherapy-induced emesis. METHODS: Comparison data used are the preclinical pharmacology as well as the design and results of clinical trials. Seven comparative studies that used granisetron, ondansetron, or tropisetron in patients who received either moderately or highly emetogenic chemotherapy are reviewed. As the study designs, patient population, chemotherapy, antiemetic doses and schedule, and methods of assessment were slightly different, the results of each study are analyzed independently. Effectiveness is assessed by emetic episodes, nausea, and patient preference. RESULTS: The preclinical pharmacologic profile is different among the 5-HT3 antagonists in terms of potency, selectivity, dose response, and duration of action. The comparative clinical trials show that a single intravenous (i.v.) dose of granisetron 3 mg is as effective as multiple (8 mg x 3) or single (32 mg) i.v. doses of ondansetron for the prevention of acute nausea and emesis due to cisplatin. In the two moderately emetogenic clinical trials, granisetron 3 mg i.v. was at least as effective as ondansetron 8 mg i.v. +/- 24 mg orally and tropisetron 5 mg i.v. Patient preference was evaluated in three of the four crossover trials: granisetron was preferred in three of four, and no preference was reported in the fourth. The one trial to compare ondansetron 0.15 mg/kg x 3 versus granisetron 10 micrograms/kg x 1 or granisetron 40 micrograms/kg i.v. demonstrated equivalent control of nausea and vomiting in patients who received cisplatin-based chemotherapy. CONCLUSION: The 5-HT3 receptor antagonists compared are highly effective antiemetic agents that have now become the standard of care for preventing chemotherapy-induced emesis. Whether the described preclinical differences among these agents are also clinically significant remains to be seen. In the comparative trials analyzed, the 5-HT3 receptor antagonists demonstrated relatively equivalent clinical efficacy. Cost analysis may favor the use of one agent over another depending on the emetogenic challenge, dose of the 5-HT3 antagonists, and number of doses recommended. Patient preference may be an important factor to be considered in future antiemetic trials. 相似文献

BACKGROUND: The localization of substance P in brain-stem regions associated with vomiting, and the results of studies in ferrets, led us to postulate that a neurokinin-1-receptor antagonist would be an antiemetic in patients receiving anticancer chemotherapy. METHODS: In a multicenter, double-blind, placebo-controlled trial involving 159 patients who had not previously received cisplatin, we evaluated the prevention of acute emesis (occurring within 24 hours) and delayed emesis (on days 2 to 5) after a single dose of cisplatin therapy (70 mg or more per square meter of body-surface area). Before receiving cisplatin, all the patients received granisetron (10 microg per kilogram of body weight intravenously) and dexamethasone (20 mg orally). The patients were randomly assigned to one of three treatments in addition to granisetron and dexamethasone: 400 mg of an oral trisubstituted morpholine acetal (also known as L-754,030) before cisplatin and 300 mg on days 2 to 5 (group 1), 400 mg of L-754,030 before cisplatin and placebo on days 2 to 5 (group 2), or placebo before cisplatin and placebo on days 2 to 5 (group 3). Additional medication was available at any time to treat occurrences of vomiting or nausea. RESULTS: In the acute-emesis phase, 93 percent of the patients in groups 1 and 2 combined and 67 percent of those in group 3 had no vomiting (P<0.001). In the delayed-emesis phase, 82 percent of the patients in group 1, 78 percent of those in group 2, and 33 percent of those in group 3 had no vomiting (P<0.001 for the comparison between group 1 or 2 and group 3). The median nausea score in the delayed-emesis phase was significantly lower in group 1 than in group 3 (P=0.003). No serious adverse events were attributed to L-754,030. CONCLUSIONS: The neurokinin-1-receptor antagonist L-754,030 prevents delayed emesis after treatment with cisplatin. Moreover, combining L-754,030 with granisetron plus dexamethasone improves the prevention of acute emesis. 相似文献

We carried out a randomized, single-blind, cross-over trial to compare the antiemetic effect, for both acute and delayed emesis, of granisetron plus dexamethasone (GRN+Dx) with that of high-dose metoclopramide plus dexamethasone (HDMP+Dx). Fifty-four patients with primary or metastatic lung cancer, given single-dose cisplatin (> 80 mg/m2) chemotherapy more than twice, were enrolled in this study. They were treated with both HDMP+Dx and GRN+Dx in two consecutive chemotherapy courses. On day 1, patients experienced a mean of 2.5 (SD = 4.3) and 0.1 (SD = 0.4) episodes of vomiting in the HDMP+Dx and the GRN+Dx groups, respectively (P = 0.0008). Complete response rate on day 1 was 45 and 90% in the HDMP+Dx and the GRN+Dx groups, respectively (P = 0.0001). Patients treated with GRN+Dx had a tendency to suffer more episodes of vomiting than the HDMP+Dx group on days 2-5, but it was not statistically significant. Twenty-four patients (57%) preferred the GRN+Dx treatment and 14 patients (33%), HDMP+Dx. In the HDMP+Dx group, nine patients (21%) had an extrapyramidal reaction, and 5 patients (12%) had constipation that lasted for at least two days. In contrast, no patients had extrapyramidal reactions, and 18 patients (43%) had constipation in the GRN+Dx group (P < 0.01). GRN+Dx was more effective than HDMP+Dx only in preventing the acute emesis induced by cisplatin. An effective treatment for delayed emesis is still needed. 相似文献

A total of 530 patients were treated in this multicenter, double-blind, double-dummy, parallel group study to compare the anti-emetic efficacy and safety of a once daily ondansetron oral regimen with a once daily i.v. dosing regimen over a 24 h period, administered to patients prior to receiving cisplatin (50 mg/m2 or greater) chemotherapy. Patients were randomized to receive a single dose of ondansetron plus dexamethasone given either orally (ondansetron 24 mg and dexamethasone 12 mg, n=262) or i.v. (ondansetron 8 mg and dexamethasone 20 mg, n=268). Complete control of emesis (i.e. no emetic episodes, no rescue and no premature withdrawal) was achieved for 85% of patients (224 of 262) in the oral group and 83% (223 of 268) in the i.v. group. No nausea was reported in 70% of patients in the oral group and 68% in the i.v. group. There were no statistically significant differences between the two groups for any of the assessments of efficacy, which included time to first emetic episode, number of emetic episodes and the worst grade of nausea occurring over the 24 h study period. Once daily ondansetron oral and i.v., in combination with dexamethasone, was well tolerated in this study. In conclusion, once daily oral ondansetron 24 mg plus dexamethasone is equally effective in the control of emesis and nausea induced by highly emetogenic chemotherapy as once daily ondansetron 8 mg i.v. plus dexamethasone. 相似文献

PURPOSE: To investigate the efficacy and safety of oral ondansetron in the control of cisplatin-induced delayed emesis in patients who do not require rescue antiemetic therapy for acute emesis. PATIENTS AND METHODS: Five hundred thirty-eight chemotherapy-naive patients who received cisplatin chemotherapy (> or = 70 mg/m2), and who were not rescued for acute emesis, were eligible to be randomized to receive one of the three oral regimens to control delayed emesis. Group I received placebo on days 2 to 6; group II received ondansetron 8 mg twice daily on days 2 and 3 and placebo on days 4 to 6; group III received ondansetron 8 mg twice daily on days 2 to 6. All patients received intravenous ondansetron (0.15 mg/kg every 4 hours for three doses) for the control of acute emesis on day 1. The number of emetic episodes on days 2 and 3 combined (days 2/3, when incidence and severity of delayed emesis were expected to be greatest) was considered the primary measure of efficacy. RESULTS: Patients who received odansetron had significantly fewer emetic episodes on days 2/3, 4, and 5 than those who received placebo (P < or = .002 on each day). Additionally, significantly more patients who received ondansetron had a complete plus major response (C+MR; < or = two two emetic episodes) than those who received placebo on days 2/3 (56% v 37%, P = .001), 4 (94% v 85%, P = .005), and 5 (98% v 88%, P = .006). Patients who received ondansetron had significantly less nausea on day 2/3 when day-1 nausea was used as the baseline score (P = .025). Patients who received ondansetron also had significantly less nausea on day 4 (P = .042) and the results approached significance on day 5 (P = .066). CONCLUSION: Oral ondansetron had a significant effect in the control of cisplatin-induced delayed emesis and nausea in patients who had not required rescue antiemetics during the acute emesis period. The control of delayed nausea and vomiting was most notable in the immediate 2 days following cisplatin administration, with the clinical difference narrowing between the two treatment arms on subsequent days. 相似文献

The effect of granisetron in preventing nausea and emesis induced by intraarterial chemotherapy was comparatively studied with a historical control group (46 cases) in 50 patients with hepatocellular carcinoma receiving intraarterial anti-tumor drugs such as cisplatin and doxorubicin. Emesis was perfectly controlled in 39 out of 50 patients in the treatment group (78%), in comparison to 33 out of 46 patients (71.7%) in the historical control group. This represented no statistical significance between the two groups. In terms of the severity of nausea, however, the granisetron group demonstrated significant superiority to the control group with 27 out of 50 patients (54%) being free of symptoms compared with 16 out of 46 patients (34.8%) in the control group. A stratified analysis of the data also demonstrated significant superiority of the granisetron group over the historical group in the number of emetic episodes and the severity of nausea in female patients, who are more predisposed to emesis. The above results confirm the usefulness of granisetron as an antiemetic agent used for the prevention of acute nausea and emesis induced by intraarterial chemotherapy. 相似文献

In this prospective, randomized, double-blinded study, we evaluated the efficacy of the oral antiemetics, granisetron and domperidone, for the prevention of postoperative nausea and vomiting (PONV) in 100 women undergoing major gynecologic surgery. Patients received either granisetron 2 mg or domperidone 20 mg (n = 50 in each group) orally 1 h before surgery. Standardized anesthetic techniques and postoperative analgesia regimens were used. Complete response (defined as no PONV and no administration of rescue antiemetic medication) for 0-3 h after anesthesia was 88% with granisetron and 52% with domperidone; the corresponding incidence for 3-24 h after anesthesia was 86% and 48% (P < 0.05). No clinically important adverse events due to the drugs were observed in any of the groups. In conclusion, the efficacy of preoperative oral granisetron is superior to that of domperidone for the prevention of PONV after major gynecologic surgery. IMPLICATIONS: We compared the efficacy of granisetron and domperidone administered orally for the prevention of postoperative nausea and vomiting in women undergoing gynecologic surgery.

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. 相似文献

Efficacy and safety of the antiemetic agent Navoban (5HT3-receptor-antagonist Tropisetron) on cytostatic-induced emesis of breast cancers and gynecological cancers was tested in 28 female patients receiving a total of 127 chemotherapy courses containing high (cisplatin), moderate high (cyclophosphamid) or moderate (for example 5 FU) emetogenic cytostatic drugs. We studied antiemetic response rates of Navoban (5 mg/d) during the first 24 hours after administration of the chemotherapy as well as response rates of the "delayed nausea and emesis" (days 2-9 after chemotherapy). A complete response was observed in 103 chemotherapy courses (= 81.1%) during the first 24 hours after chemotherapy and in 93 courses (= 73.2%) for the "delayed emesis". Treatment failures (more than 5 vomiting episodes) during the first 24 hours were present in four courses and for the "delayed emesis" in 11 courses. The side effects of Navoban such as constipation, headache or tiredness were minimum. Therefore no patient refused to receive the necessary chemotherapy. Navoban is, with its single dose application, an effective therapeutic drug for the prevention of nausea and emesis in patients receiving a chemotherapy. 相似文献
