Ultra-low dose drug delivery system for contraception
The patent application (Publication Number: US20230404911A1) describes a drug delivery system designed for contraception by administering it to a subject's vaginal tract. The system consists of a core containing ethinyl estradiol and etonogestrel, covered by a membrane. When in the vaginal tract, the system delivers effective doses of both compounds over a specified period, producing a contraceptive effect. Importantly, the system releases less than 0.013 mg per day of ethinyl estradiol, with the period of effectiveness ranging from 21 days to 3 months post-administration.
Furthermore, the patent details the method of contraception using this system, involving positioning it in the vaginal tract for a specific period before removal. The system releases controlled amounts of ethinyl estradiol and etonogestrel daily, ensuring contraceptive efficacy. The patent also specifies the composition of the core and membrane, highlighting the use of specific thermoplastic polymers or elastomers. Overall, the patent outlines a novel drug delivery system for contraception that offers precise dosing and extended effectiveness, potentially improving user compliance and convenience.
