CONTEXT: Pruritus associated with hepatic or renal failure can be a troublesome symptom, refractory to treatment and associated with significant physical and emotional distress and a reduction in quality of life for patients already burdened with chronic disease. Serotonin has been implicated as a possible pathological mediator, and, therefore, 5HT(3) antagonists have been suggested as a possible therapeutic intervention. OBJECTIVES: This review of the literature systematically explores the role of ondansetron in the management of cholestatic or uremic pruritus. METHODS: Electronic databases were systematically searched for randomized controlled trials examining the role of ondansetron in cholestatic or uremic pruritus between 1966 and 2008. RESULTS: Five randomized controlled trials were included in this systematic review: three for cholestatic pruritus and two for uremic pruritus. All trials examined ondansetron vs. placebo, with differing treatment protocols. Overall, three studies showed no benefit to ondansetron over placebo; however, two studies in cholestatic pruritus showed small reductions in pruritus with questionable clinical significance. CONCLUSION: Ondansetron was demonstrated to have negligible effect on cholestatic or uremic pruritus on the basis of a limited number of studies.
