Abstract
본 발명의 방법을 통해 제조된 이중-층의 고온용융 압출물인 약제학적 조성물은, 종래 고온용융 압출 방법에 의해 제조되는 약제학적 조성물에 비해 쓴 맛에 대한 차폐 능력(taste masking)이 증가될 수 있다. 또한, 속방 및 서방 등의 방출 양상이 서로 다른 약물을 동시에 함유하는 약제를 제조할 수 있고, 배합금기(incompatible)한 두 가지의 약물을 이중-층 시스템을 이용하여 내층과 외층에 탑재한 형태의 약제를 제조할 수 있다. 이 외에도, 급속한 약물 방출을 억제하는 탬퍼링 방지(tamper resistance) 효과를 나타낼 수 있어, 종래 기술에 의해 제조되는 고온용융 압출 기술보다 효과적인 형태의 약제를 제조할 수 있다.
Description
도 2는 고온용융 압출물이 하나의 약물을 포함할 때, 단일-층 및 이중-층에 따른 고온용융 압출물의 약물 방출 효과의 확인을 나타낸다. 고온용융 압출물이 이부프로펜을 포함할 때 반복 압출한 경우에서 이중-층(bi-lyaer)로 약물이 방출되고 있음을 확인할 수 있다.
도 3는 고온용융 압출물이 두 가지가 혼합된 약물을 포함할 때, 단일-층 및 이중-층에 따른 고온용융 압출물의 약물 방출 효과의 확인을 나타낸다. 두 가지 약물은 글리메피리드 및 메트포르민의 두 가지 약물을 혼합하였을 때 글리메피리드의 방출 양상을 나타내며, 글리메피리드는 메트포르민과 달리 서방이 아닌 속방의 형태로 방출되어야 하나, 단일 압출하였을 때 약물이 상대적으로 느린 속도로 방출된다.
