[High dosage acetylsalicylic acid administration for prevention of acute cerebral ischemia].

6 studies with a placebo-controlled, double blind, randomized protocol on the effect of acetylsalicylic acid (ASA) in a dosage of higher than 100 mg/day have been published. The preventive effect for TIA was obvious without a significant difference between males and females. The effect on secondary cerebral ischemic attacks after completed infarcts has not been sufficiently proven with the ASA. The preventive effect for cerebral ischemic attacks in normals without preceding strokes or TIA has not been shown.
