Letrozole Mode of Action

Letrozole Mode of Action

Letrozole is a medication that is commonly used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing the levels of estrogen in the body. This is important because estrogen can fuel the growth of certain types of breast cancer.

How Does Letrozole Work?

Letrozole works by inhibiting the enzyme aromatase, which plays a key role in the production of estrogen. Aromatase is responsible for converting androgens, which are male hormones, into estrogen. By blocking this enzyme, letrozole decreases the amount of estrogen in the body.

By lowering estrogen levels, letrozole can help slow or stop the growth of estrogen-sensitive breast tumors. This can be particularly beneficial for postmenopausal women whose breast cancer is hormone receptor-positive, meaning that their cancer cells have receptors for estrogen.

Potential Side Effects

Like any medication, letrozole can cause side effects. Some common side effects of letrozole include hot https://letrozolebuy.com/prod/letrozol-teva-filmtabletten-2-5mg-100-stuck/ flashes, fatigue, joint pain, and bone thinning. In some cases, letrozole may also increase the risk of osteoporosis.

In conclusion, letrozole is an important medication in the treatment of breast cancer. By inhibiting the production of estrogen, letrozole can help slow or stop the growth of hormone receptor-positive breast tumors. If you have been prescribed letrozole, be sure to follow your doctor’s instructions carefully and discuss any concerns or questions you may have.
