Abstract
The present invention relates to a non-hormonal, biocompatible, and biodegradable intravaginal device for the delivery of spermiostatic, spermicidal and anti-infectious agents. The present invention also relates to methods of contraception using such a device, as well as the prevention and treatment of sexually transmitted diseases and vaginal infections through the application of the device.
Claims17
An intravaginal contraceptive device, comprising:
- a biocompatible support structure, configured to be inserted into a woman's vagina;
- the support structure comprising a non-hormonal contraceptive composition, the support structure and composition adapted to provide sustained release of contraceptively effective amounts of the composition into the woman's vagina for three days;
- the contraceptive composition which is released for the three days, comprising:
- a sperm-mobility reducing effective amount of ferrous gluconate;
- or ferrous sulfate and combinations thereof;
- ascorbic acid in an effective amount to increase viscosity of cervical mucus;
- and
- a pH buffering effective amount of ampholines;
- the composition which is released for the three days formulated to maintain a vaginal pH at a spermiostatic level.
