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.

The activity of (-)eburnamonine, a substance acting on the cerebral circulation and metabolism, was compared with that of nicergoline in a double-blind study carried out on a group of 28 patients (16 males and 12 females), suffering from established chronic brain ischemia. The treatment consisted of the administration for the first 5 days of 80 mg/day and for the following days of 60 mg/day of (-)eburnamonine, in 14 subjects. Nicergoline was administered to the other 14 subjects: 20 mg/day for the first 5 days and then 15 mg/day. The treatment was protracted for at least 20 days. (-)Eburnamonine appeared to influence some symptoms more rapidly and significantly than nicergoline. After 20 days of treatment the overall improvement obtained with (-)eburnamonine was 31 and 18% with nicergoline. No side effects or impairment of the biochemical tests appeared during either treatment.

The effects of a new eburnamenine derivative (3 beta,14 alpha, 16 alpha)-(+/-)-14,15-dihydro-20,21-dinoreburnamenin-14-ol (vindeburnol, RU 24722) on EEG, on brain energy metabolism and on local cerebral blood flow (LCBF) and in different experimental models of cerebral insufficiency were compared with those of vincamine, vinburnine (1-eburnamonine), dihydroergotoxine mesilate and nicergoline. Vindeburnol at 2 mg/kg i.v., increased the EEG resistance time in rats subjected to asphyxia anoxia and at 10 mg/kg s.c., significantly improved the electrocortical recovery of gerbils subjected to a 10-min cerebral ischemia. Vindeburnol (10 mg/kg i.p.) significantly retarded glucose, phosphocreatine and adenosine triphosphate utilization and lactate production in mouse brain during 10 s of decapitation ischemia. The cerebral metabolic rate was 10.34 mmol/kg/min, which was about 50% of the control value. At 10 mg/kg i.p., the product induced a slight and transient increase in LCBF. Vincamine improved the early phase of the postischemic electrocortical recovery in the gerbil, had no effect on cerebral energy substrates and slightly increased the LCBF for 15 min. Dihydroergotoxine mesilate improved the early phase of the electrocortical recovery in gerbils subjected to ischemia, did not significantly modify the energy substrates and rapidly increased the LCBF, which was normal after 30 min. Vinburnine and nicergoline were inactive in the cerebral insufficiency models used and did not significantly modify cerebral energy metabolism. These results show that vindeburnol has a different pharmacological profile from vincamine, vinburnine, dihydroergotoxine mesilate and nicergoline, and suggest that vindeburnol may be therapeutically effective in cerebral insufficiency.
