NCT00889499

  Purpose

Chronic pain is associated with hypersensitivity of the central nervous system. The drug under investigation (tropisetron) has been shown in animal studies to attenuate central hypersensitivity. It has therefore the potential to be effective in chronic pain. We compare two doses of tropisetron with placebo in patients with chronic pain. We measure pain intensity and parameters that assess central hypersensitivity.
