Pharmacotherapy of cerebral ischemia in cocaine dependence.

Abstract

This paper will examine how cerebral perfusion deficits in cocaine abusers may be a target for pharmacotherapy. The review covers five areas: (1) cerebral ischemia and neuropsychological impairment in cocaine abusers, (2) neuroimaging evidence for cerebral perfusion defects in cocaine abusers, (3) mechanisms for cocaine induced cerebral thrombosis, (4) neurotoxicity from cerebral ischemia and excitatory amino acids, (5) glutamate antagonists as potential treatment agents for cocaine induced neurotoxicity. Several pharmacotherapies are suggested including antiplatelet agents and excitatory amino acid (EAA) antagonists such as lamotrigine. Clinical trials in cocaine abusers with cerebral perfusion defects are indicated and EAA antagonists hold promise as they are developed for stroke treatment.
