title: A double-blind, randomized study of two different dosage regimens of intravenous dolasetron in patients receiving high-dose cisplatin chemotherapy.
abstract: This study compared the antiemetic efficacy and safety of two different intravenous (i.v.) dolasetron dosing regimens in patients receiving their first course of high-dose (> or = 80 mg/m2) cisplatin. Of 30 patients enrolled, 14 received a single i.v. dolasetron dose (0.6 mg/kg) before cisplatin and 16 received a multiple i.v. dose regimen (0.6 mg/kg x 3) given before and after cisplatin. Complete plus major responses were achieved by 71% (10/14) of patients who received single-dose dolasetron and by 50% (8/16) of those who received the multiple-dose regimen. Forty-three percent (6/14) of patients who received the single dose had a complete response compared with 25% (4/16) who received multiple doses. Multiple doses resulted in less nausea at 24 hr following cisplatin; however, differences were not statistically significant. Both regimens were well tolerated, with mild headache (33%) and diarrhea (13%) the most common adverse events. This study demonstrated that a single 0.6-mg/kg dose of dolasetron given before chemotherapy provides equivalent antiemetic efficacy to three 0.6-mg/kg doses given before and after high-dose cisplatin chemotherapy; thus, there was no additional antiemetic benefit by using the multiple-dose regimen.
