Abstract

The characteristics of the controlled drug release were studied for biodegradable transdermal drug delivery system. A biodegradable polymeric matrix was prepared from chitosan, silver sulfadiazine, and glycerine. The release behavior of silver sulfadiazine from chitosan matrix was consistent with the Higuchi's diffusion controlled model. The release time was delayed by increasing the content of silver sulfadiazine and thickness of the matrix, whereas decreased as glycerine concentration increased. The apparent constant (K) of release rate was proportional to the content of drug or glycerine and the thickness of chitosan matrix. These results indicated that chitosan matrix shows some potential as a drug delivery system for transdermal therapeutic application.

Chitin을 강알칼리로 탈아세틸화시켜 합성한 chitosan을 증류수에 팽윤시킨 다음 글리세린을 가하여 교반하였다. 이 고분자 용액에 약물인 silver sulfadiazine을 가하여 경피흡수용 고분자 matrix을 제조하였다. 이렇게 제조된 고분자 matrix로부터 약물의 방출거동과 고분자 matrix 변수와의 상관관계 등을 조사함으로써 지속적이고 조절된 경피흡수제형으로서의 사용 가능성과 특성을 조사하였다. 고분자 matrix 내의 약물의 함유량과 matrix의 두께가 증가할수록 약물의 방출시간은 더 지연되었다. 그러나 글리세린의 함유량이 증가함에 따라 약물의 방출시간은 오히려 감소하였다. 약물의 함유량, 글리세린의 함유량 및 matrix의 두께가 증가할수록 겉보기 방출속도상수(K)값도 증가하였다.이상과 같이 chitosan은 의약의 방출조절형제제로서 가능성을 나타냈으며, 약물로 사용된 silver sulfadiazine의 방출거동은 Higuchi model에 따른 확산으로 생각되었다.
