Abstract

The invention belongs to the technical field of medicines, and discloses a pharmaceutical composition for treating depression. The pharmaceutical composition is composed of a raw material agomelatine and auxiliary materials, wherein the raw material agomelatine is micronized agomelatine. Based on a deep research of the physical and chemical properties of agomelatine, the scientific researchers of the company accidentally find that agomelatine can be micronized for obtaining agomelatine with a certain particle size to produce a preparation, the invention has the advantages of uniform quality and good dissolution rate.

Description

Technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a pharmaceutical composition for treating depression with a raw material of micronized agomelatine. [0002] The micronization in the present invention refers to a method including but not limited to mechanical grinding to reduce the particle size of the raw material to 75 μm or less. The raw material particle size in the present invention refers to at least 50% (more than or equal to 50% and less than 100%) of the particle size less than or equal to 75 μm. Background technique [0003] Depression is a common mental illness. The main clinical manifestations are low mood, decreased interest but not lost, pessimism, slow thinking, lack of initiative, self-crimination, poor diet and sleep, and fear of suffering from various diseases. This kind of disease makes the whole body feel uncomfortable. In severe cases, suicidal thoughts and behaviors may occur. Depression is the dise...
