Patent number: 11633360Abstract: The present invention relates to a method for preparing biodegradable microspheres using a single-phase mixed solution containing water, alcohol, and dichloromethane. Provided is a method for preparing a biodegradable microsphere having a uniform drug loading efficiency by preparing and using a single-phase mixed solution in which no phase separation occurs without using a thickener and a surfactant. The preparation method of the present invention has the feature of keeping the content of a loaded drug uniform until a final biodegradable microsphere is prepared, by using a single-phase mixed solution in which no phase separation by a solvent occurs in the preparation process. Thus, the preparation method of the present invention is remarkably useful for the preparation of biodegradable microspheres.Type: GrantFiled: April 22, 2019Date of Patent: April 25, 2023Assignee: HLB PHARMACEUTICAL CO., LTDInventors: Sang Hwi Lee, Mijung Kim, Dooyong Jeong, Mi Jung Kim, Wan Joo Kim, So Kyoung Joo
