摘要:
An intravaginal ring for the controlled release of at least one bioactive agent may further contain at least one of a non-bioabsorbable microparticulate ion-exchanging polymer, a fully bioabsorbable polymeric matrix, a biostable hydrophilic elastomeric polymeric matrix, a biostable amphiphilic elastomeric polymeric matrix, a biostable elastomeric polymeric matrix containing an inorganic microparticulate, and a biostable elastomeric porous polymeric matrix, each to aid in the release and/or modulate the release of the bioactive agent.
