Levan acetate를 이용한 hydrocortisone의 방출 제어
- Published : 2001.11.07
Abstract
The preparation, characterization and drug release behaviour of hydrocortisone(HC) loaded levan acetate microparticles were investigated. Hydrophobic levan acetate was prepared by chemical modification of hydrophilic levan and micro particles were made by dialysis method or solvent evaporation method. The morphology of levan acetate was observed by SEM and drug release profiles were investigated at pH 7.4 and pH 1.2. Newly synthesised levan acetate can be used for carrier of drugs.
