摘要: Chronic administration of haloperidol induced supersensitivity the pre- and postsynaptic dopaminergic receptors in rat brain. The response presynaptic was determined by an enhanced inhibitory effect apomorphine on dopamine synthesis after gamma-butyrolactone injection. This change receptor function detected both nigrostriatal mesolimbic pathways. Haloperidol also increased 3H-spiperone binding sites striatal membranes, indicating receptors. Subsequent prolonged treatment with high doses L-DOPA/carbidopa resulted a decrease sites, but had no supersensitive It is suggested that tardive dyskinesia may be state chronic L-DOPA have differential these sites.
