Abstract:
A contraceptive drug delivery system is provided in the form of a controlled release, bioerodible pellet for subdermal implantation. The pellet is bioerodible, and provides for the sustained release of a contraceptive agent over an extended time period. Bioerosion products are water soluble, bioresorbed, or both, obviating the need for surgical removal of the implant. Methods of using the drug delivery system, including in female contraception, are also provided.

Claim (Index 28):
A drug delivery system for use in female contraception, comprising a subdermally implantable bioerodible, lipophilic pellet that provides for controlled release of a progestogen throughout an extended drug delivery time period that ends with complete bioerosion of the pellet in situ, the pellet comprising:\n an amount of a progestogen selected from etonogestrel and levonogestrel which, following subdermal implantation of at least one pellet into a female subject, results in a serum level of the progestogen sufficient to achieve contraceptive efficacy during an effective drug delivery time period of about six months to about four years within the extended drug delivery time period; and an excipient composition comprising (a) a first lipidic excipient having a first aqueous solubility and a second lipidic excipient having a second aqueous solubility, where the first aqueous solubility is lower than the second aqueous solubility by at least 10% and the weight ratio of the first lipidic excipient to the second lipidic excipient is in the range of about 3:1 to about 50:1.
