New microneedle patches can prevent bacterial infections
Scientists from Sweden have tested a modified plaster with microneedles, which is used to transport drugs into the blood. This time it was used to accelerate the therapeutic effect of skin diseases.
Visually, this is a small square that can fit on the phalanx of the finger. Its base is a non-toxic polymer with needles for a series of hypodermic injections. The latter are made of a bio-soluble material, which disappears in the body after the drug is transferred into the blood.
The principle of the "work" of the patch is quite simple. Microneedles attach to the skin, penetrate the top layer, bypassing the nerves, and transfer drugs into the intercellular fluid and then into the blood. The last stage is the release of the "injections".
According to scientists, in case of severe damage to the body, you have to use the oral method. There is no drug delivery locally, through blood and skin. And this, in addition to the beneficial effect on viral infections, contributes to the occurrence of side effects.
For physicians, the microneedle patch is a solution to problems with the treatment of patients with skin infections. The medicine is sent to the place of localization, and does not spread throughout the body, along the way often causing irreparable harm.
Swiss researchers tested the patch under laboratory conditions. Experiments were carried out to deliver vancomycin to the site of infection through the skin of pigs and humans. The effectiveness of the administration of drugs through a patch with needles has been proven.
