Abstract

The invention discloses a blonanserin pharmaceutical composition. Mannitol and microcrystalline cellulose are used as filling agents, wherein the weight percentage of the mannitol is 40%-55%, and the weight percentage of the microcrystalline cellulose is 20%-30%. The blonanserin pharmaceutical composition is high in stability and has evident advantages of product yield increase, cost reduction, industrialization realization and clinical application, dissolubility can be effectively improved, and bioavailability is improved evidently.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a blonanserin pharmaceutical composition and a preparation method thereof. Background technique [0002] Blonanserin, its chemical name is: 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydroaromatic Octa[b]pyridine, molecular formula: C23H30FN3, molecular weight: 367.5. It was first disclosed by EP0385237 and was developed by Sumitomo Corporation of Japan. It was launched in Japan in January 2008. It is a drug that specifically acts on 5-HT2 receptors and D2 receptors. It is the closest atypical antipsychotic drug in the market. Drugs that act selectively. Significantly improve the positive symptoms (such as hallucinations, delusions, etc.) and negative symptoms (such as depression, hypokinesia, etc.) etc.) and other adverse reactions, and its safety and tolerance are significantly better than traditional antipsychotic drugs. [0003] Orally disi...
