title: The effect of administration rate on cisplatin-induced emesis.
abstract: In an attempt to determine the influence of administration time on cisplatin-induced emesis, 20 adults previously untreated with cisplatin were enrolled into this double-blind study. Twenty patients were randomly assigned to receive high-dose cisplatin (greater than 100 mg/m2) either by a one-hour infusion or by an eight-hour infusion. All patients received antiemetic therapy with metoclopramide 2 mg/kg intravenously one-half hour before cisplatin administration, and 1 1/2, 3 1/2, 5 1/2, and 8 1/2 hours after cisplatin administration. Patients in the eight-hour infusion group experienced significantly fewer emesis episodes than did patients in the one-hour infusion group. The median of emesis episodes in the eight-hour group was one (range, 0 to 2) and in the one-hour group was three (range, 0 to 8). In patients receiving high-dose cisplatin plus metoclopramide, increasing the administration time from one hour to eight hours resulted in a small but significant decrease in emesis episodes. The cisplatin infusion rate should be considered as a variable in cisplatin-antiemetic trials.
