Randomized Controlled Trial
Oral magnesium treatment in patients with neuropathic pain: a randomized clinical trial.
Studies in animals and in patients have suggested that magnesium (Mg), a physiological blocker of N-methyl-D-aspartate receptor, could have an antinociceptive effect in painful situations. This randomised, double-blind, controlled trial in two parallel groups aims at studying oral Mg effects in patients with neuropathic pain. ⋯ This clinical trial displays a large placebo response and could not demonstrate any significant difference in pain alleviation after a month of oral treatment between Mg and placebo in patients suffering from neuropathic pain. Frequency of pain paroxysms and emotional impact will be explored in future studies as they constitute major aspects of pain alleviation in chronic pain conditions.
