Ondansetron Plus Metopimazine Compared With Ondansetron Plus Metopimazine Plus Prednisolone as Antiemetic Prophylaxis in Patients Receiving Multiple Cycles of Moderately Emetogenic Chemotherapy

Abstract
PURPOSE: To compare the antiemetic efficacy and tolerability of ondansetron plus metopimazine with ondansetron plus metopimazine plus prednisolone during nine cycles of moderately emetogenic chemotherapy. PATIENTS AND METHODS: A total of 221 women with stage I or II breast cancer and no prior chemotherapy who were scheduled to receive adjuvant chemotherapy with intravenous cyclophosphamide, fluorouracil and methotrexate or cyclophosphamide, epirubicin, and fluorouracil given every 3 weeks were included in a double-blind parallel trial. Patients were randomized to 3 days of oral treatment with ondansetron plus metopimazine, or ondansetron plus metopimazine plus prednisolone. Ondansetron was administered as 8 mg bid, metopimazine as 30 mg qid, and prednisolone as 50 mg qd. RESULTS: In all, 216 patients (97.7%) were assessable for efficacy during a total of 1,462 cycles. In cycle 1, complete protection from emetic episodes/nausea day 1, days 2 through 5, and days 1 through 5 was achieved in 84.4%/51.4%, 82.6...
