Therapy of chronic consequences of brain ischemia. Comparison between two drugs acting on brain circulation and metabolism.

With the purpose to define the specific activity of substances acting on the cerebral circulation and metabolism, (-)eburnamonine and cinnarizine were compared in a double-blind study carried out in a group of 106 elderly patients suffering from established chronic brain ischemia. The photoscintigraphic and rheoencephalographic studies carried out on some of the patients showed that only (-)eburnamonine had a clear-cut activity on brain circulation. (-)Eburnamonine also showed an activity on kidney circulation. With regard to the clinical picture, a statistical evaluation of the results obtained showed that both drugs improve psychic disturbances and the overall clinical picture. Cinnarizine appears to influence, to a slightly greater extent, some neurological symptoms, while (-)eburnamonine exerts a significantly better action on daily living activities and general psychic efficiency.
