Experiment resultsindicate that, the hydrogen bonds between hydroxyl of PVA and salicylic acid leads to thecompatibility between them. The drug release rate is accelerated with the rise oftemperature and decreased with the increase of drug loadage. The fitting result suggests afirst-order kinetic equation for salicylic acid release.

结果表明：PVA羟基与水杨酸之间氢键作用有利于两者的相容性；随着介质温度的上升，药物的释放速率增加；随着药物装载量的增加，药物的累积释放率降低；PVA水凝胶中水杨酸的释药规律符合一级释放模型。
