➤ What is the correct term for medication delivered through an adhesive skin patch?
Transdermal is the correct term. It denotes systemic drug delivery through intact skin using an adhesive patch. Transdermal patches allow medication to cross the stratum corneum into dermal capillaries for systemic circulation. By contrast, transcutaneous often refers to across-skin procedures and transmuscular means delivery through muscle tissue.
