Effect of cinnarizine on the brain mitochondrial oxidative system, antioxidant blood activity, and the rat behavior in hypoxia

The effect of cinnarizine on the functional state of brain mitochondria, the activity of blood antioxidant system, and the behavior of rats was studied under model hypoxic hypoxia conditions. A four-day treatments with cinnarizine (50 mg/kg, twice per day via a gastric tube) prevents the hypoxic brain edema development, restores NAD+ dependent oxidation of a succinate substrate, normalizes emotional-exploratory activity, and causes hyperlocomotion of the experimental animals, while not influencing a high level of activity of the blood antioxidant system.
