The jewels have arrived to avoid pregnancy

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, no test has yet been performed in humans. "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, "said Professor Mark Prausnitz. Regents at the Georgia Institute of Technology's School of Chemical and Biomolecular Engineering, whose work has been published in the famous Journal of Controlled Release.

In fact, the patch is already used to administer drugs that prevent vertigo, help quit smoking and control the symptoms of menopause. But it is clear that until now, 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 at the rear of rodent slopes for approximately 16 hours and with a rest period of approximately eight hours, simulating sleep times during which women typically do not wear them. .

The patch contained three layers: a raincoat comprising a sticker to hold it on a pendant, at the bottom of a wristwatch or on 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 contraception in humans, the back of the ear loop should be changed periodically, probably once a week.

The specialists are convinced that this technique could possibly be used to administer other pharmaceutical products, even if it would only be suitable for skin-permeable medicinal products requiring the administration of sufficient quantities to adapt to stamps. But since then, there has been a big step forward.
