According to the domperidone impurity detection method, the impurity A, the impurity B, the impurity C, the impurity D + E, the impurity F, the impurity H, the impurity I and the impurity J in domperidone can be detected, the separation degree of each impurity peak is high, and the content of each impurity can be measured at the same time. The detection method disclosed by the invention is good in specificity, high in sensitivity and good in experimental verification results such as linearity, repeatability, solution stability and accuracy inspection. The result provides a new method for impurity detection of domperidone, and provides guarantee for preparation of domperidone tablets and other preparations.

A method of treating an episode of acute exacerbation of schizophrenia by intramuscular administration of a long-acting injectable depot composition containing risperidone is provided. The method provides a substantial reduction in PANSS (both positive and negative scales) and CGI-S scores within about eight days after administration of the composition and for up to at least four weeks. The method is used to treat a subject suffering a first-time episode of or a relapse of severe to moderate symptoms associated with schizophrenia. The method does not require loading doses of risperidone in the depot composition and does not require supplementation with oral risperidone after administration of the depot composition.

A method of treatment of mental disorder of a subject includes the steps of: normalizing an expression of both DRD1 and DRD5, which belong to DRD1-like family, of the subject to a preset standard level. The DRD1 / 5 level and expression can be increased or decreased bidirectionally by targeting an upstream promoter sequence of DRD1 / 5. The promoter activity of DRD1 / 5 can be attenuated by using an antipsychotic which directly targets the DRD1 / 5 promoter. The antipsychotics being used are typical and / or atypical antipsychotic medications such as Haloperidol,Risperidone, Clozapine and Cariprazine. The treatment is also useful for the subject with an impaired constitutive expression of DRD1 / 5 gene. The method can be used to treat schizophrenia, autism, depression, mania and bipolar disorders by normalizing the DRD1 / 5 expression level. The promoter gene sequencing of DRD1 and / or DRD5 can also be used for quantitative mental health screening through comparing with a standard sequence database.
