Russian scientists have achieved a new medical breakthrough, using nanotechnology to create "smart patches." This technology enhances the effectiveness of drugs administered transdermally.
These ultra-thin patches with microneedles cause no pain and release medication gradually directly into the targeted area. While still experimental, this model represents a step toward a fear-free, injection-free medicine.
: Smart patches are equipped with sensors and microscopic mechanisms capable of delivering drugs directly to the site of injury or disease, while monitoring the dose and timing of drug release.
, doctors only used long-acting pain-relieving bandages, such as the fentanyl bandage used to treat cancer patients. Its effects lasted from 12 to 24 hours.
However, doctors faced a problem: how to develop a bandage capable of delivering a large dose of medication in a timely manner? This was because healthy skin has limited permeability to drugs.
by finding a solution: galvanic currents. Under their influence, lymphatic and circulatory circulation in the treated area increases, in addition to enhancing tissue absorption and stimulating metabolic and nutrient processes.
Simultaneously, bandages equipped with microscopic mechanisms charged by a galvanic current accelerate connective tissue regeneration.
include plans to apply this new system of long-acting topical therapy (analgesic, hormonal, and other effects) in treating tumors or endocrine disorders, such as insulin injections for diabetes. However, trials in the field of transdermal therapy are still ongoing.
