Contraceptive jewelry arrives, a new way of taking care of oneself – 03/27/2019

Researchers at the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology (United States) They have created contraceptive jewelry (earrings, watches, rings or necklaces) that could improve family planning and, as a result, prevent unwanted pregnancies due to misuse of contraception.

These are patches that contain contraceptive hormones They are incorporated into jewelry in contact with the skin, which allows the body to absorb the drug.

"The more contraceptive options available, the more likely it is that every woman's needs can be met.Because wearing jewelry can already be part of a woman's daily routine, this technique can facilitate adherence to drug therapy and help some women prevent unwanted pregnancies.

According to a report published in the medical journal Journal of Controlled Release, initial tests have suggested that contraceptive jewelry can provide the user with a sufficient amount of hormones to act as a contraceptive method. However, Human tests have not been done yet.

In fact, the patch is already used to administer drugs that prevent vertigo, support cessation of smoking and control the symptoms of menopausealthough they have never been incorporated into jewelry. "There is a lot of experience in the manufacture and use of conventional transdermal patches and now we are making the smaller patch and using jewelry to help apply them," Prausnitz added.

The method has been tested on animals. Specifically, scientists placed the patches on the backs of rodent slopes for 16 hours and with an eight-hour rest period, simulating the sleep hours that women typically do not wear.

The patch contains three layers: a raincoat comprising a sticker to hold it on a pendant, at the bottom of a wristwatch or at the inner surface of a necklace or a ring; an intermediate layer with the contraceptive drug in solid form; and an outer with an adhesive to adhere to the skin so that the hormone can be transferred. Once on the skin, the drug can enter the blood and circulate in the body.

The tests suggested that although levels dropped when they were removed, the patch could produce the necessary amounts of the hormone in the blood.. However, if the technique is ultimately used for human contraception, the back of the ear loop should be changed periodically, probably once a week.

This technique could possibly be used to administer other pharmaceuticals, although it is only suitable for skin-permeable drugs. that require the administration of small enough quantities to fit in the patches.
