[Study on the water-soluble composition release of compound Danshen sustained-release tablet].
OBJECTIVE
To study on the release of compound Danshen sustained-release tablet and the evaluate method of Chinese material medica compound sustained-release preparation.


METHODS
Rotating basket method and HPLC were employed.


RESULTS
Through the determination of 6 time-point samples, the water-soluble compositions of compound Danshen sustained-release tablet had a Well-balanced release behavior with a zero-grade release model or Higuchi release model.


CONCLUSIONS
Compound Danshen sustained-release tablet had a zero-grade release model. The method was rapid and stable and could be applied to evaluate the water-soluble composition release of compound Danshen sustained-release Tablet.
