Abstract
본 발명자들은 뇌졸중 치료와 관련된 임상적 지식을 바탕으로 뇌졸중으로 인한 후유증의 치료에 실데나필과 ROCK 저해제를 병용하기 위해 연구한 결과, 실데나필과 ROCK 저해제를 각각 단독 투여한 경우와 대비해 실데나필 및 ROCK 저해제를 병용 투여한 경우 뇌졸중으로 인한 인지 기능의 저하가 유의적으로 개선되거나 정상 대조군에 비해 인지 기능이 증진됨을 최초로 확인하였는바, 본 발명에 따른 약학적 조성물은 뇌졸중으로 인해 발생하는 인지 기능 저하와 관련된 후유증의 치료 또는 연구 및 인지 기능 증진과 관련된 연구에 유용하게 이용될 것으로 기대된다.
