[The effects of mexidol in pain syndromes].

Models of neuropathic pain syndrome and adjuvant arthritis were used to study the effect of mexidole, an antioxidant from the 3-hydroxypyridine group. Mexidole was indicated to produce no preventive effect in pain syndromes, but to exhibit a therapeutic one. The use of mexidole in combination with the agents activating the monoaminergic systems in the central nervous system showed the presence of their reciprocal effect in neuropathic pain syndrome and its absence in adjuvant arthritis. Possible mechanisms of action of mexidole were also discussed.
