Abstract
본 발명에 따른 HEMA와 상분리 방법으로 제작된 약물(비타민 E)을 중합한 약물 전달 콘택트렌즈의 제조방법은 생체적 합성과 생분해성이 우수하여 약물 전달매체에 응용되어, 상분리 방법으로 제작된 약물입자의 중합비율을 다르게 하여 안구 질환의 예방 및 치료에 맞춘 콘택트렌즈를 제조할 수 있으므로 사람마다 다른 콘택트렌즈를 적용하여 약물 전달 효과를 크게 할 수 있는 등의 현저한 효과가 있다.
Description
테이블 2는 본 발명의 비교예 및 실시 예로써 하이드로젤에 약물(리도케인, 비타민 E)을 직접 주입하였을 때와 상분리 방법으로 제조된 약물(리도케인, 비타민 E) 전달 콘택트렌즈의 확장 지수 및 확산 계수를 나타내었다.
도 1는 비교 예로써 약물(리도케인(a))과 P 124, matodextrin을 혼합하여 80도의 고온에서 30분간 가열하여 정적상태의 시간 변화에 따른 용액의 상태를 나타낸 그림이다.
도 2는 비교 예로써 약물(비타민 E(b))과 P 124, matodextrin을 혼합하여 80도의 고온에서 30분간 가열하여 정적상태의 시간 변화에 따른 용액의 상태를 나타낸 그림이다.
도 3는 본 발명의 실시예에 따른 상분리 방법으로 제조된 약물(리도케인(a))을 입도분석기를 이용하여 약물입자를 측정한 그래프이다.
도 4는 본 발명의 실시예에 따른 상분리 방법으로 제조된 약물(비타민 E(b))을 입도분석기를 이용하여 약물입자를 측정한 그래프이다.
도 5은 본 발명의 실시예에 따른 상분리 방법으로 제조된 약물(리도케인)의 안정된 상태를 확인하기 위하여 광학현미경으로 촬영한 약물 입자와 약물 전달 콘택트렌즈의 표면을 나타낸 그림이다.
도 6는 본 발명의 실시예에 따른 상분리 방법으로 제조된 약물(비타민 E)의 안정된 상태를 확인하기 위하여 광학현미경으로 촬영한 약물 입자와 약물 전달 콘택트렌즈의 표면을 나타낸 그림이다.
도 7는 본 발명의 또 다른 실시예 및 비교예에 따른 하이드로젤 약물 전달 콘택트렌즈의 PBS pH 7.4 환경에서의 약물 방출 패턴을 나타내는 그래프이다.
