description The present invention relates to a sustained release pharmaceutical composition capable of forming in-situ implants and a preparation method therefor and, to a sustained release pharmaceutical composition capable of forming in-situ implants and a preparation method therefor, in which goserelin and a biodegradable polymer are each prepared into a sol state by being dissolved in a pharmaceutically acceptable solvent, and quickly transform into a solid state on a site after being administered thereto, so that initial drug release is suppressed and at the same time drug efficacy can be maintained for a long time period of more than one month with a single injection. La présente invention concerne une composition pharmaceutique à libération prolongée capable de former des implants in situ et son procédé de préparation, et une composition pharmaceutique à libération prolongée capable de former des implants in situ et son procédé de préparation où de la goseréline et un polymère biodégradable sont chacun préparés dans un état de sol en étant dissous dans un solvant pharmaceutiquement acceptable, et se transforment rapidement en un état solide sur un site après leur administration, de sorte que la libération initiale de médicament est supprimée et en même temps l'efficacité du médicament peut être maintenue pendant une longue période de plus d'un mois avec une seule injection. 본 발명은 인-시튜 임플란트를 형성할 수 있는 서방형 약학 조성물 및 이의 제조방법에 관한 것으로 고세렐린 및 생분해성 고분자가 약학적으로 허용 가능한 용매에 용해되어 있는 졸(sol) 상태로 각각 제조되어, 투약 후 신속하게 그 자리에서 고체상태로 변환되어 초기 약물 방출이 억제됨과 동시에 1회 주사로 1개월 이상 장기간 약효를 유지할 수 있는 인-시튜 임플란트를 형성할 수 있는 서방형 약학 조성물 및 이의 제조방법에 관한 것이다.
