摘要：
The present invention relates to a matrix for sustained-release preparation comprising an ester formed at a terminal carboxyl group of a straight-chain polyester which essentially consists of an .alpha.-hydroxymonocarboxylic acid. The matrix is stable to light, heat, moisture, coloring etc., and is of low toxicity. The sustained-release preparation produced by using the ester of the present invention offers stable drug release over an extended period of time, ensuring sustained stable effect. Furthermore, the sustained-release preparation does not show excess drug release just after administration.
