Steroid delivery systems for contraception.
Scientific disciplines not normally associated with pharmaceutical development have been employed to enhance the effectiveness and attractiveness of two approaches to steroidal contraception. The use of a bioerodible polymeric carrier for predictable systemic steroidal administration has removed the largest hurdle to the development of a subcutaneous contraceptive implant. A polymeric progesterone delivery system has provided a method for localizing hormonal contraception in the uterine cavity. Extensions of these technologies may provide two useful tools in limiting fertility in an already overcrowded world.
