Low-dose intravenous ondansetron (8 mg) plus dexamethasone: an effective regimen for the control of carboplatin-induced emesis

Abstract

Twenty-nine patients with gynecologic malignancies were treated with a fixed low dose of intravenous ondansetron (8 mg) plus dexamethasone (20 mg) in an effort to develop an effective and less expensive antiemetic regimen for the control of carboplatin-induced emesis. Twenty-six (90%) of the women participating in this trial experienced complete control of both acute nausea and vomiting (developing within the first 24 h after chemotherapy administration), while 27 (93%) patients exhibited either complete or major control (< or = 2 episodes of vomiting, < or = 5 episodes of retching, minimal interference with eating) of emesis. On the basis of our experience in this trial, we conclude that the combination of low dose (8 mg) intravenous ondansetron plus dexamethasone is a well-tolerated and highly cost-effective antiemetic strategy for individuals receiving carboplatin-based chemotherapy.
