ABSTRACT

Transdermal drug delivery (TDD) is a hopeful way to give medicines because it avoids first-pass digestion and allows for the drug to be released slowly over time. But the skin's natural protective qualities make it hard for drugs to get through. Several penetration boosters and methods have been created to make the skin more permeable and reach acceptable drug concentrations. Penetration boosters are chemicals that temporarily break down the skin's protective function. This makes it easier for active medicinal ingredients to get through the epidermis and into the bloodstream. We look at the different kinds of penetration enhancers in this paper. These include chemical enhancers like fatty acids, detergents, and alcohols; physical ways like iontophoresis, microneedles, and ultrasound; and new approaches like nanocarriers and lipid-based systems. Each booster works by going after different layers of skin, mainly the stratum corneum, to either make the lipid bilayers more fluid or open up brief channels for drugs to move through. It is talked about in depth how these enhancers work, such as by changing the structure of proteins or lipids in the skin or by starting electrical currents. The paper also talks about how hard it can be to choose the right enhancers because of things like skin itching, drug safety, and the need for exact dose control. Hybrid methods, which combine more than one technique, are also looked into because they might be able to get better results with fewer side effects. One more thing that is looked at is how transdermal drug delivery methods could be used to treat long-term diseases like pain and hormone replacement therapy. New ideas in how to make drugs and improve them are likely to make TDD systems much more useful and useful in more situations
