摘要：
A vaginal drug delivery system includes a device formed of porous material that holds a flowable therapeutic formulation. The device, preferably in a soft, prewetted state, is inserted into the vagina to reside typically at or near the cervix where it continuously releases the flowable therapeutic formulation through its outer surface which is in contact with the vaginal surfaces. In operation, the flowable therapeutic formulation migrates via capillary forces from a reservoir that is centrally located in the device and through a covering that envelopes the reservoir.
