[Glutamatergic mechanisms in alcohol dependence--genetic, molecular-biological and neuropharmacological findings]

Abstract

A number of preclinical and clinical findings suggest that the glutamate system, especially NMDA-receptors has a major function in neuropsychiatric disorders related to chronic alcoholism. Other findings suggest, that glutamatergic mechanisms may also play a role for the addictive process itself including craving and addiction memory. A number of genetic and molecular-biological findings and more recent neuropharmacological studies point in this direction. NMDA-modulators and antagonists have been found to be possible or even clinically effective so called anti-craving-drugs. A better understanding of the glutamatergic mechanisms in alcohol dependence may therefore also be of relevance for the development of new anti-craving-drugs and therapy-research.
