Transdermal systems are provided for administering an estrogen and/or a progestin to a mammalian female. The systems are monolithic, having a drug reservoir that serves as the means for ensuring adhesion to the skin during drug administration. The drug reservoir includes the active agent(s), a low molecular weight organic acid as a permeation enhancer, and an additional vehicle, in an adhesive matrix. Methods for using the systems for transdermal delivery of active agents are also provided, including methods for providing hormone replacement therapy and for preventing ovulation. |
