<p>A composition prepared by containing or blending a physiologically active non-peptide substance and a biodegradable polymer having two or more carboxylic groups at its end or a salt thereof features: (1) larger content of the physiologically active non-peptide substance can be contained, as well as release of the same can be controlled or accelerated, whereby secure pharmaceutical effect is achieved; (2) when the physiologically active non-peptide substance causes subcutaneous stimulation, an activity of canceling the stimulation by strongly acidic group at its end is expected; and (3) high glass transition point and high stability.</p> |
