Abstract

The goal of an antihypertensive treatment is to prevent "end-organ" damage. Cerebral vascular complications are among the most important because they are life threatening and can occur even at an early stage of the disease. Recently, it has been shown that cilazapril can decrease the mortality of stroke-prone rats, suggesting a decrease in the incidence of strokes, which occur spontaneously in these animals. The present article reviews the different functional and morphological changes that may explain the cerebral protective effects of cilazapril, such as the normalization of cerebral vascular reserve, decrease in the media, increase in the external diameter, and normalization of the mechanics and endothelial function of cerebral arterioles. In addition, the inhibition by cilazapril of injury-induced proliferation of smooth muscle cells and the infiltration of the endothelium by macrophages could prevent the development of atherosclerosis.
