케토코나졸의 고체분산계에 관한 연구 = Studies on Solid Dispersion System of Ketoconazole

다국어 초록 (Multilingual Abstract)

Dissolution profiles of ketoconazole in solid dispersion system (SDS) were investigated in the second fluid (pH 6.8) for the dissolution test (KPV). PVP K-30 and methyl cellulose were used as carriers in SDS, and chloroform as a solvent. Computer optimization technique was applied to obtain an optimum formula of SDS, and the following results were obtained; 1) Dissolution rate of ketoconazole in SDS was larger than that of pure ketoconazole in the second fluid of pH 6.8. 2) PVP K-30 and methyl cellulose were good carriers for SDS of ketoconazole. Moerover, PVP K-30 was better than methyl cellulose. 3) The optimum formula of ketoconazole SDS obtained from computer optimization technique was chloroform 175 ㎖, PVP K-30 5g and methyl cellulose 0.2g per 1g of ketoconazole. 4) The experimental value of A_(60) (Amount released from ketoconazole tablet during 60 minutes) obtained from SDS by optimum formula agreed well with the value calculated by polynomial regression equation.
