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