Contraceptive ring against pregnancy and HIV

Researchers at Northwestern University have come up with a new option: An intravaginal ring that helps prevent pregnancy while simultaneously releasing low doses of an antiretroviral drug that reduces a woman’s risk of contracting both HIV and genital herpes, Fox News reports.

Patrick Kiser, an associate professor of biomedical engineering and obstetrics and gynecology at Northwestern, devised the ring with the hopes that it would offer women more control over both disease and pregnancy prevention. 

Kiser and his team at Northwestern spent five years developing the two-inch ring, which releases doses of the contraceptive levonorgestrel and the common antiretroviral HIV medication tenofovir after being inserted in the vagina. Similarly to the NuvaRing, women can insert the device on their own. Women can then leave the ring in for up to 90 days, removing it briefly for cleaning if necessary.

The researchers have conducted extensive testing of the ring on both small and large animal models, and are now in the process of submitting an Investigational New Drug Application to the FDA.
