Randomized Controlled Trial Clinical Trial
Ondansetron therapy for uremic pruritus in hemodialysis patients.
Pruritus is a distressing symptom affecting up to 90% of dialysis patients. Conventional treatment with antihistamines is often ineffective and may have unacceptable side effects. Serotonin (5-hydroxytryptamine type 3 [5-HT(3)]) is known to enhance pain perception and pruritic symptoms through receptors on sensory nerve endings. ⋯ There was no difference in predialysis biochemistry test results or dialysis efficacy during treatment phases. Ondansetron does not improve pruritus in hemodialysis patients. Use of antihistamines decreased with both ondansetron and placebo.
