Abstract

Excessive production of free radicals is known to lead to cell injury in a variety of diseases, such as cerebral ischemia. In this review, we describe some of the numerous studies that have examined this oxidative stress and the efficiency of antioxidant strategies in focal cerebral ischemia. Besides using genetically modified mice, these strategies can be divided into three groups: (1) inhibition of free radical production, (2) scavenging of free radicals, and (3) increase of free radical degradation by using agents mimicking the enzymatic activity of endogenous antioxidants. Finally, the clinical trials that have tested or are currently testing the efficiency of antioxidants in patients suffering from stroke are reviewed. The results presented here lead us to consider that antioxidants are very promising drugs for the treatment of ischemic stroke.
