摘要：
A variety of different intravaginal drug delivery devices are described for the delivery of estrogens and progestins. The release rate of estrogens and progestins can be controlled by varying the matrix material or by the application of a thin coating. The intravaginal drug delivery devices may be composed of one or more individual compartments. By controlling various physical and chemical parameters, non-zero release rates of the estrogen or progestins may be achieved.
