| 摘要 |
<p>The invention relates to drug delivery systems comprising a water-soluble polymer matrix and a bioactive agent entrained therein, said water soluble polymer matrix containing at least 50 wt. % of polyoxazoline having a molar mass of at least 5 40,000 g/mol. The drug delivery systems of the present invention offer the advantage that the bioactive agent is readily released when the drug delivery system is contacted with water. The drug delivery system can be in the form of a solid dispersion, a mucoadhesive sheet, a tablet, a powder, a capsule.</p> |
