PURPOSE: A porous PLGA microsphere containing simvastatin and a method for preparing the same are provided to enable persistent drug release.CONSTITUTION: A porous PLGA(poly(lactic-co-glycolic acid)) microsphere contains simvastatin in a porous structure. The diameter of the microsphere is 100-500 um. The surface and inside of the microsphere have a plurality of holes. A method for preparing the porous PLGA microsphere comprises: a step of dissolving PLGA and simvastatin in DCM(dichloromethane) and adding distilled water to form a water-in-oil phase a step of PVA(polyvinyl acetate) to the W/O phase to form a W/O/W1 phase and a step of centrifuging the reactant.COPYRIGHT KIPO 2012본 발명에 따른 다공성 PLGA 미소구체는 다공성 구조 내에 심바스타틴(simvastatin)이 내재되어 있으며, 다중 에멀젼 방법을 이용하여 제조 가능하다. 상기 다공성 PLGA 미소구체는, 생체적합성과 생분해성이 우수하고 지속적인 약물의 방출이 가능하며, 조직공학용 생체재료로 다양하게 활용 가능하다.
