Estradiol/Levonorgestrel Patch for Menopause

This trial aims to evaluate how two hormone-containing skin patches affect the skin of women experiencing menopause. Researchers seek to determine if one patch causes more skin irritation or allergic reactions than the other. Participants will wear the patches on different body parts to compare results. Women who are naturally or surgically postmenopausal, weigh 90 kg or less, and are generally healthy may qualify for this trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Research has shown that Estradiol/Levonorgestrel skin patches are generally easy to use and well-tolerated. These patches already help alleviate menopause symptoms like hot flashes. However, studies have identified some side effects. Common ones include skin reactions at the application site, vaginal bleeding, and breast pain. Other possible side effects are headaches and nausea.

Unlike other treatments for menopause that typically involve oral or injectable hormone therapies, the Estradiol/Levonorgestrel Transdermal Delivery System (TDS) offers a unique patch-based approach. This transdermal system delivers hormones directly through the skin, which may help maintain stable hormone levels and reduce side effects often associated with pills. Researchers are excited about the potential for this patch to provide a more convenient and potentially safer alternative to traditional hormone replacement therapies, which often require daily dosing and can be harder on the digestive system. By focusing on a combination of estradiol and levonorgestrel, this method aims to effectively manage menopausal symptoms while offering a simpler, potentially more comfortable option for patients.

Studies have shown that the estradiol/levonorgestrel patch effectively treats menopausal symptoms like hot flashes and night sweats. The patch releases hormones through the skin, which helps reduce these symptoms. Research indicates that it significantly decreases the frequency and severity of hot flashes. Users have reported quick relief, making it a promising option for menopausal women. Additionally, the patch adheres well to the skin, ensuring consistent hormone delivery. Participants in this trial will apply the estradiol/levonorgestrel patch differently: one group will place half of the patch on the right buttock and the other half on the left, while the other group will do the reverse.¹²⁶⁷⁸
