Cerebral ischemia: pharmacological bases of drug therapy
1Institut für Pharmakologie and Toxikologie, Philipps-Universität, Marburg, Deutschland.
Abstract:
The cascade of reactions caused by ischemia in brain tissue is complex and not completely understood, but intensive investigation has led to convincing hypotheses. A disturbed calcium homeostasis and oxygen radicals seem to play a major role in postischemic neuronal damage. In accordance to these hypotheses drugs with different mechanisms of action have been developed. The aim of this paper is to give an overview over pathobiochemical mechanisms in cerebral ischemia and possibilities of pharmacological intervention.
Insights
Cerebral ischemia triggers complex reactions, with disturbed calcium homeostasis and oxygen radicals causing neuronal damage. This paper reviews pathobiochemical mechanisms and pharmacological interventions for brain ischemia.
