AbstractDroperidol, metoclopramide, and prochlorperazine were compared in a double-blind crossover trial to determine their relative effectiveness in preventing and controlling the nausea and vomiting caused by cisplatin-containing chemotherapy. Twenty-five patients receiving cisplatin-containing chemotherapy for various malignancies were entered into this trial with 14 patients completing the three-drug randomization sequence. This was the patient's first exposure to cisplatin. Each antiemetic was administered in a diluted 50 ml i.v. injection over 15 minutes beginning 0.5 hour before cisplatin and 1.5, 3.5, 5.5, and 8.5 hours after cisplatin. Dosages of antiemetics for doses of cisplatin greater than or equal to 100 mg/sq m were droperidol 2.5 mg, metoclopramide 2 mg/kg, or prochlorperazine 5 mg in each infusion. For doses of cisplatin less than 100 mg/sq m, the dosages were droperidol 2.5 mg for the first two doses and 1.25 mg for subsequent doses, metoclopramide 1 mg/kg, or prochlorperazine 5 mg for each dose. The median number of emetic episodes for the first 24 hours were as follows: droperidol 3.2; metoclopramide 1.8; prochlorperazine 3.7. There was a significant difference in number of emetic episodes demonstrating antiemetic superiority of metoclopramide over both droperidol and prochlorperazine. For these 14 patients completing the trial, eight preferred metoclopramide, two preferred prochlorperazine, one preferred droperidol, and three had no preference. At the doses used in this study, the antiemetic efficacy of metoclopramide was superior to either droperidol or prochlorperazine.
