New birth control patch would administer contraception via self-injecting needles

Atlanta, Ga., Jan 17, 2019 / 05:01 pm (CNA/EWTN News).- Scientists and researchers from the Georgia Institute of Technology in Atlanta are working on a birth control patch that would inject a contraceptive drug into women’s skin through biodegradable microneedles.

The quarter-sized patch would be applied to the skin for five seconds, allowing the needles “painlessly” to pierce the skin and break away, remaining in the body to slowly administer the contraceptive hormone levonorgestrel.

Currently, the needles are designed slowly to release the contraceptive hormone over the course of one month, though the team of scientists has said that the goal would be to develop a six-month patch.

In an article on the patch recently published in Nature Biomedical Engineering, the authors said it could eventually be used instead of the birth control pill, or other forms of long-term birth control such as hormone shots or implantable devices such as IUDs.

“Non-hormonal contraceptive methods, such as condoms and diaphragms, provide physical barriers for pregnancy protection, but these barrier methods, even when accompanied by spermicide, usually have high failure rates due in part to poor patient acceptance and compliance with correct use,” the study, authored by Dr. Mark Prausnitz and team, states.

“Hormonal contraceptives, such as oral pills, vaginal rings, intrauterine devices, subdermal injections and implants, generally provide a better level of effectiveness, but either require frequent dosing, which has significant compliance problems, or delivery by healthcare professionals, which can be especially problematic in low-income countries,” it adds.

“Hence, there has been tremendous interest in a contraceptive that is safe and effective, enables long-term contraception, facilitates good patient access and compliance through self-administration, and has low cost suitable for use globally.”

In the study, the scientists expressed hope that the patch could make long-term contraceptives more widely available, especially in developing countries, since women will be able to apply the patch themselves.

“To provide greater access to contraception, we developed a delivery system for contraception based on a microneedle patch designed to enable self-administration of a long-acting contraceptive that is safe, effective and low cost,” they said.

The study, which was received by Nature Biomedical Engineering in March 2018, was made possible through funding from the United States Agency for International Development.

The Western push to increase access to contraceptives and abortion has been denounced by critics as ideological colonization.

“By what moral right do Westerners send the message that the world would be a better place with fewer Africans in it?” Mary Eberstadt, senior research fellow at the Faith and Reason Institute, told CNA in 2018. She was responding to a report from the Guttmacher-Lancet Commission, which declared a need for universal access to contraception and birth control within the next 12 years, particularly in the developing world.

“Such campaigns are going to look as ugly in history’s rearview mirror as the twentieth-century eugenics movement does today,” she said at the time.

Nigerian Catholic Obianuju Ekeocha, the author of “Target Africa,” has also been an outspoken pro-life advocate who has opposed bringing contraceptives to Africa and other developing places.

“Unlike what we see in the developed Western world, there is actually very high compliance with Pope Paul VI’s Humanae vitae. For these African women, in all humility have heard, understood, and accepted the precious words of the prophetic pope,” Ekeocha wrote in a 2012 open letter to Melinda Gates.

The patch is still in development, and has only been tested on rats thus far. Scientists cited concerns about skin irritation at the site of the patch and the need for more clinical trials before the patch could be released to the general public.

The microneedle patch technology could also potentially be used to deliver vaccines throughout remote and underdeveloped areas as well, the study noted.
