What Are Bloqueadores de la aromatasa?
Bloqueadores de la aromatasa are medications designed to inhibit the enzyme aromatase, which plays a crucial role in https://todos-esteroides.com/product-category/inhibiteurs-de-laromatase/ the biosynthesis of estrogen. These drugs are primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women, helping to reduce estrogen levels and slow the growth of estrogen-dependent tumors.
How Do Bloqueadores de la aromatasa Work?
The enzyme aromatase converts androgens into estrogens. By blocking this enzyme, bloqueadores de la aromatasa decrease estrogen production in the body. This mechanism is especially beneficial in cases where estrogen fuels the growth of certain types of breast cancer, making these drugs an essential component of hormonal therapy.
