A contraceptive patch can prevent pregnancy for 6 months



The new contraceptive patch can prevent women from pregnancy for up to six months, experts found.

A single-use patch should only be applied to the skin for a few seconds.

After placing the varnish on the skin, the microglass is torn and under the skin's surface of the woman, reports The Sun.

Tiny needles are painless and made from the same material as the soluble seams used in surgery, so they are safely absorbed by the body.

Within a few months the needles are able to release the contraceptive drug into the bloodstream.

The patch may be more effective than the current options – eliminating the need for a woman to take a pill everyday.

It may also be more popular than other long-term contraceptives, such as a coil or implant, that require a doctor or nurse to implant or inject.

However, the plaster is still in the early stages of development and tested only on mice.

Professor Mark Prusnitz of the Georgia Institute of Technology in Atlanta said: "There is a strong interest in providing more contraceptives of prolonged duration.

"Our goal is to allow women to take long-acting contraceptives with a microdrive patch that will be applied to the skin for only seconds once a month."

Professor Prausnitz said the goal is to develop a patch that can carry enough hormone to provide contraception for six months at a time.

His team used the same microgrowth technology that was developed for administering vaccines.

They built a clinical trial of an influenza vaccine at the Emory University in the phase.

This study showed that patches can be safely used to deliver the vaccine.

Since microwaves are so small, they are only in the upper layers of the skin, and volunteers involved in the study of the influenza vaccine do not complain of any pain.

But Professor Prausnic acknowledged that additional research and testing was needed to find out exactly how contraceptive spots would work in humans.

"Because we use a well-established contraceptive hormone, we are optimistic that the patch will be an effective contraceptive," he said.

"We also expect that the potential irritation of the skin at the site of application of the patch will be minimal, but these expectations should be checked in clinical trials."

If new patches are approved for use, they may be the first self-contained long-acting contraceptive that does not require a regular needle.

So far, tests in mice have only measured the level of hormones and did not attempt to determine if the patch can prevent pregnancy.

But, scientists have developed a human version of the patch, which they hope to check.

Prof. The Prosecutor added: "There is a great interest in minimizing the number of necessary medical interventions.

Therefore, it is desirable to use a contraceptive patch that lasts more than a month, especially in countries where women have limited access to medical care.

"But since microgrid are, by definition, small, there are limitations on how much a drug can be included in the patch."

Gregory Copf, a Family Health International spokeswoman, who supported the study, said: "Microgaming is a breakthrough in healthy women.

"This self-administered long-term contraceptive will give women an independent and convenient control over their fertility, which will have a positive effect on the health of the population by reducing both unwanted and unforeseen pregnancy"

Although the cost has not yet been set, Professor Prosunits said he expects the patch to be cheap enough to be used in developing countries.

The study was published in the journal Nature Biomedical Engineering.
