Transdermal Application

Meaning

Transdermal Application is a method of drug delivery where an active pharmaceutical agent, often a hormone or peptide, is administered directly onto the skin surface to be absorbed through the dermis and epidermis into the systemic circulation. This route bypasses the gastrointestinal tract and first-pass metabolism in the liver, offering a more stable and continuous absorption profile compared to oral administration. It is a preferred clinical method for maintaining consistent serum hormone concentrations.
