INTRODUCTION: Chronic methamphetamine use results in persistent neuropsychological deficits in abstinent methamphetamine dependent (AMD) subjects. We examined the hypothesis that elevated concentration of cerebral glutamate (Glu), an excitatory neurotransmitter and neurotoxin, occurs in human AMD. MATERIALS AND METHODS: We examined 40 subjects, 18 of whom were AMD, abstinent more than 3 weeks ...

The behavioral effect and acute toxicity of methamphetamine were tested alone and in combination with quinine in rats. Quinine prolonged and increased the effect of methamphetamine. The enhancement of methamphetamine-induced stereotyped behavior was very marked when quinine was given prior to or simultaneously with methamphetamine. However, the time for onset of methamphetamine-induced stereoty...

Methamphetamine is a potent psychomotor stimulant and a major drug of abuse. There is currently no effective medication available for treatment for methamphetamine addiction. The present study investigated the role of the dopamine D3 receptor on IV methamphetamine self-administration and its effect on methamphetamine induced neurochemical changes. Acute administration of the putative D3 recepto...

OBJECTIVE Since cocaine and psychostimulant dependence are related to increased dopamine release, antipsychotics have been tried to reduce their reinforcing properties. A meta-analysis was undertaken to assess the efficacy and tolerability of antipsychotics in cocaine- or stimulant-dependent patients. DATA SOURCES We searched PubMed, Cochrane Library databases, and PsycINFO from database ince...
