Long-term administration of antipsychotic drugs to animals induces super-sensitive mesolimbic postsynaptic dopamine receptors. It is possible that a similar process can occur in man. Following a reduction in the dose of antipsychotic medications, or their complete discontinuation, mesolimbic dopamine receptor supersensitivity could be reflected in rapid relapse of schizophrenic patients, the development of schizophrenic symptoms in patients with no prior history of schizophrenia, or in the necessity for ever-increasing doses of long-acting depot fluphenazine to maintain a remission.
长期给动物服用抗精神病药物会诱导中脑边缘系统突触后多巴胺受体超敏。人类也可能发生类似过程。在减少抗精神病药物剂量或完全停药后,中脑边缘多巴胺受体超敏可能表现为精神分裂症患者迅速复发、既往无精神分裂症病史的患者出现精神分裂症症状,或为维持病情缓解而需要不断增加长效氟奋乃静的剂量。
