Summary
Brief summary
Healthy post menopausal women (n=3)will be recruited into a pilot study to investigate the absorption of estradiol following a single application to the skin of estradiol coated microparticles. A single dose topical application will be applied to the right submandibular skin area (top of the neck just below the jaw line). The primary objective is to assess whether estradiol is absorbed into the circulation of the eligible women
recruited onto study and assess if there are any local reactions. This will be assessed by serum hormone blood levels (over time) and skin photography of the application site.
