Possible role of calcium entry blockers in brain protection

Abstract

Cerebral protection in its proper meaning is understood as a method to suppress electrophysiological and metabolic activity of the CNS. More generally, methods which avert injury to the brain, particularly when anticipated, can be considered as cerebral protection. Prevention of secondary brain damage following a primary ischemic or traumatic lesion is a particularly important goal of cerebral protection. The concept of secondary brain damage implies that secondary changes in principle should be prevented by inhibition of the pathomechanisms involved. The introduction of Ca2+ antagonists into the treatment of traumatic or ischemic cerebral injury is an excellent example of a powerful therapeutical method, which is developed on the basis of an understanding of the underlying pathophysiological mechanisms. Ca2+ antagonists may interfere at various levels, e.g. blood flow, cellular destruction or other forms of secondary brain damage. Intracellular Ca2+ overload appears to be a common pathway to failure of pertinent cell functions, and eventually cell death. Thus, inhibition of this process might be central for cell and, hence, cerebral tissue protection. However, the use of Ca2+ antagonists requires careful considerations of the ...Continue Reading

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.
