Letrozole: Description of the Drug

Letrozole is a medication commonly used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing the production of estrogen in the body. Estrogen can promote the growth of hormone-receptor-positive breast cancer cells.

When taken orally, letrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogen. By blocking this process, the drug helps lower estrogen levels in postmenopausal women, thereby slowing down or stopping the growth of cancer cells that rely on estrogen to fuel their growth.

Indications for Use

Letrozole is typically prescribed for postmenopausal women with hormone-receptor-positive early-stage breast cancer after surgery, radiation, or chemotherapy. It may also be used as a first-line treatment for advanced breast cancer in postmenopausal women.

Additionally, letrozole has been shown to be effective in increasing the chances of pregnancy in women with polycystic ovary syndrome (PCOS) by inducing ovulation.

Possible Side Effects

Like all medications, letrozole can cause side effects. Common side effects may include hot flashes, fatigue, joint pain, headache, and nausea. Some women may also experience bone thinning or osteoporosis due to decreased estrogen levels. It is important to discuss any concerns or side effects with your healthcare provider.

In rare cases, letrozole may cause more serious side effects such as liver problems, cardiovascular issues, or an increased https://letrozoleonline.com/products/letropuren-25-mg-filmtabletten/ risk of fractures. If you experience any unusual symptoms while taking this medication, seek medical attention immediately.

Overall, letrozole is an important medication in the treatment of hormone-receptor-positive breast cancer and other conditions related to estrogen levels. It is essential to follow your healthcare provider’s instructions carefully and report any side effects promptly to ensure safe and effective treatment.
