Abstract
본 발명의 가용화 방법에 의해 레바미피드가 투명한 수용액 상태로 완전히 용해될 뿐만 아니라, 상기 가용화 방법에 의해 제조된 액제는 가속 시험에서 2개월이 지난 후에도 안정한 용액 제형을 유지하며, 안구조직, 특히 각막 및 결막에서의 레바미피드의 흡수율 및 지속율 증가에 따른 생체이용율이 개선이 확인되었다. 따라서, 본 발명의 가용화 방법에 의해 제조된 수용액은 레바미피드를 포함하는 안구건조증 치료용 액제로 유용하게 사용될 수 있다.
Description
도 2는 제조된 레바미피드 2% 수용액의 안정성 시험에서, 안정성 시험 시작시의 표준액(A) 및 레바미피드 2% 수용액(B); 및 2개월 경과 후의 표준액(C), 상온에서의 레바미피드 2% 수용액(D) 및 40 ℃에서의 레바미피드 2% 수용액(E)에 포함되어 있는 레바미피드를 측정한 크로마토그램이다.
도 3은 레바미피드 현탁액(Mucosta 2%)(A) 및 본 발명의 가용화 방법에 의해 제조된 레바미피드 2% 수용액(B)을 토끼의 눈에 투여한 후, 시간에 따라 각막, 결막 및 방수에서의 레바미피드의 농도를 측정한 결과이다.
