Double-blind crossover trial of single vs. divided dose of metoclopramide in a combined regimen for treatment of cisplatin-induced emesis.
In a double-blind crossover antiemetic study in cisplatin-treated cancer patients, metoclopramide 4 mg/kg as a single intravenous dose (regimen A) was compared with 3 mg/kg in two doses (regimen B). In both regimens, metoclopramide was combined with dexamethasone and diphenhydramine. 65 consecutive, chemotherapy-naïve inpatients (45 males and 20 females) treated with high doses (at least 50 mg/m2) of cisplatin entered the study and 54 completed both treatments. Complete protection from vomiting and nausea, mean number of emetic episodes, mean maximum intensity of nausea and mean duration of emesis or nausea were similar with the two antiemetic regimens. 23 patients (43%) did not express a treatment preference, while 16 (30%) preferred regimen B and 15 (28%) preferred regimen A. Side-effects were similar with the two metoclopramide schedules. A combined antiemetic regimen of a single high dose of metoclopramide (4 mg/kg) can preserve efficacy and tolerability and thus should be preferred.
