We evaluated the effects of nicergoline on antioxidant defense enzymes (detoxifying enzymes), during chronic treatment with haloperidol in rats. Chronic use of haloperidol (10 weeks, 1.5 mg/kg/day) induces a significant decrease in glutathione reductase, glutathione peroxidase and superoxide dismutase activity, in selected areas of the brain. Co-administration of nicergoline (20 days, 10 mg/kg/day) significantly restored the activity of these enzymes to levels comparable to those observed in control rats. These observations suggest beneficial effects of nicergoline in the prevention and in the treatment of haloperidol-induced side effects.

Abstract
We evaluated the effects of nicergoline on antioxidant defense enzymes (detoxifying enzymes), during chronic treatment with haloperidol in rats. Chronic use of haloperidol (10 weeks, 1.5 mg/kg/day) induces a significant decrease in glutathione reductase, glutathione peroxidase and superoxide dismutase activity, in selected areas of the brain. Co-administration of nicergoline (20 days, 10 mg/kg/day) significantly restored the activity of these enzymes to levels comparable to those observed in control rats. These observations suggest beneficial effects of nicergoline in the prevention and in the treatment of haloperidol-induced side effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
