Description

technical field [0001] The invention belongs to the field of drug development, in particular to a selective 5-HT 2A Receptor inhibitor and its preparation method and application. Background technique [0002] Schizophrenia is one of the most prevalent mental illnesses, with an incidence of about 1% worldwide. In our country, the prevalence rate is 7.11‰ in urban areas and 4.26‰ in rural areas. Cities are significantly higher than rural areas. The prevalence is roughly equal in both sexes. The disease mostly occurs in young adults, the most common in 15 to 35 years old, 50% of the patients are 20 to 30 years old, and it is rare before the age of 10 (children's schizophrenia) and after 40 to 50 years of age (late onset schizophrenia). disease). Most epidemiological data in my country suggest that the prevalence rate of females is higher than that of males. The gender difference is more obvious in the age group over 35 years old; the prevalence rate in urban areas is high...
