[Prevention of nausea and emesis during cytostatic therapy. Antiemetic efficacy of high-dosage oral metoclopramide without and with prednisone].

In a randomized trial of 58 cancer patients receiving strongly emetogenic cytostatic drugs (cisplatin or comparable cytostatic agents, alone or in combination), the anti-emetic action of oral metoclopramide was tested, alone or combined with prednisone. Patients of group A (33 during 46 treatment cycles) received three times 50 mg metoclopramide and three times 25 mg prednisone. Those of group B (25 patients during 35 cycles) received three times 50 mg metoclopramide. The drug was given two hours before as well as two hours and six hours after administration of the cytostatic drugs. Good or satisfactory prophylaxis of nausea and vomiting (no or at most three vomits) was achieved during 37 cycles (80.5%) of group A patients and 30 (85.7%) of group B patients. Complete absence of vomiting was obtained in 52% of cycles in group A, 46% of cycles in group B; complete absence of nausea in 39% and 32%, respectively. There was no statistically significant difference between the two treatments in their preventive action. Three times 50 mg metoclopramide (with or without prednisone) four hours apart during one cytostatic-drug cycle was well tolerated by patients in both groups and can be recommended as a simple, practical prophylaxis of nausea and vomiting in the course of strongly emetogenic treatment of cancer.
