| Abstract: | OBJECTIVE Breviscapine sustained-release tablets （BST） were formulated with hydroxypropyl-methylcellulose as the matrix material and the release mechanism of the tablets was studied. METHODS The effects of determination methods, main excipients and accelerated stability test on the sustained-release character were studied. RESULTS The release results of BST coincided with sustained-release quality standard, and drug release pattern was in accorded with the first order kinetics. CONCLUSION BST has a good sustained-release behavior, while the preparation method is simple, and reasonable in large-scale production. |
