The estradiol transdermal patch is a hormone replacement therapy (HRT) designed to deliver estradiol (a form of estrogen) through the skin to address various conditions related to estrogen deficiency. Primarily used by women experiencing menopause, it alleviates symptoms like hot flashes, vaginal dryness, and itching, while also preventing osteoporosis in postmenopausal women. Additionally, it serves as an estrogen source for women with conditions like hypogonadism or primary ovarian failure. The patch offers advantages over oral medications, including consistent dosing, avoidance of digestive side effects, and improved patient convenience.
