Chitosan is a polycatonis biopolymer that can form gel in acidic environment so that can be used as a hydrophilic matrix in controlled release drug delivery system. In this research, propranolol hydrochloride controlled release granule was made in chitosan matrix. Granules were made by wet granulation method with variety of matrices, i.e. chitosan, hydroxypropyl mthylcellulose (HPMC) and ethyl cellulose (EC). HPMC and EC were used as a comparing matrix. The release rates of propranolol HCl from matric were determined by using dissolution apparatus type I with 50 rpm stirring rotation in acidic media of pH 1,2 and base media of pH 7.5 for 8 hours. Sample was taken at certain time and the samples were anakyzed by spetrophotometer. The result showed that the release of propranolol hydrocholride from chitosan matrix was the slowest compared to the other matrices. |
