Transdermal Therapy

Meaning

Transdermal Therapy is a non-invasive route of drug administration where a pharmaceutical agent is delivered across the skin barrier and into the systemic circulation to achieve a therapeutic effect on distant target organs. This method, typically employing patches, gels, or creams, is highly favored for steroid hormones like estrogen and testosterone because it effectively bypasses the first-pass metabolism in the liver. It provides a convenient and relatively steady, sustained release of the active compound.
