We searched MEDLINE and The Cochrane Library to find high quality evidence aboutCa2＋ channel blocker in primary or secondary stroke prevention and summarized the avaliable evidence. The results show that in addition to the effect on hypertension, Ca2＋ channel blocker has antiartherosclerotic effect and can reduce the frequency rate of stroke. It has played an important role in primary stroke prevention. But concomitantly it can increase the risk of heart disease and as yet there is no evidence on secondary stroke prevention. Accordingly, Ca2＋ channel blockers should not be recommended as the first-fine medicine for stroke prevention.
