Transdermal Estrogen

Meaning

Transdermal Estrogen refers to a therapeutic delivery method for estrogen replacement where the hormone is absorbed directly through the skin into the systemic circulation, bypassing the gastrointestinal tract and first-pass metabolism in the liver. This method is typically administered via patches, gels, or sprays and is a common approach in Hormone Replacement Therapy (HRT) for managing menopausal symptoms and preventing osteoporosis. Clinically, it offers a distinct pharmacokinetic advantage over oral administration by avoiding the hepatic effects that can increase clotting factors.
