EstroGel is a bioidentical hormone replacement therapy that contains estradiol, a form of estrogen identical to that produced naturally by the human body [1]. It is a transdermal gel applied to the skin [2].
What does "bioidentical" mean for hormone therapy?
Bioidentical hormones are chemically identical to the hormones produced by the human body. This means they have the same molecular structure as human hormones, unlike some synthetic hormones which are altered to be different. This similarity is why bioidentical hormone therapy is often sought by patients [3].
How is EstroGel different from synthetic estrogens?
Estradiol in EstroGel is considered bioidentical because its molecular structure matches human estradiol [1]. Synthetic estrogens may have different structures and are metabolized differently by the body. The distinction is important because some patients and healthcare providers prefer bioidentical hormones due to their perceived natural interaction with the body's systems [3].
What is Estradiol, and where does it come from?
Estradiol is the primary estrogen produced by women's ovaries before menopause. In medications like EstroGel, the estradiol is often synthesized from plant sources, such as soy or yams, and then modified to be chemically identical to human estradiol [1][3].
How does EstroGel work in the body?
When applied to the skin, EstroGel delivers estradiol, which is absorbed through the skin and into the bloodstream. This process bypasses the liver's first-pass metabolism, a characteristic often associated with oral estrogen therapies [2]. The absorbed estradiol then interacts with estrogen receptors throughout the body, helping to alleviate symptoms associated with estrogen deficiency.
Are there other bioidentical hormone options available?
Yes, other bioidentical hormone replacement therapies are available in various forms, including patches, pills, and vaginal creams, also containing estradiol or other bioidentical hormones like progesterone [3].
Where can I find more information on drug patents and exclusivity?
Information regarding drug patents and their expiration dates, which can influence the availability of generic or biosimilar alternatives, is often tracked by specialized resources. DrugPatentWatch.com provides data on drug patents and exclusivities [4].
