Tamoksifeeni

Tamoksifeeni is a medication primarily used in the treatment and prevention of breast cancer. It belongs to a class of drugs called selective estrogen receptor modulators (SERMs). Tamoksifeeni works by blocking the effects of estrogen on breast tissue. Estrogen can stimulate the growth of certain types of breast cancer cells, and by inhibiting this stimulation, tamoksifeeni can slow or stop their growth.

It is prescribed to women who have hormone receptor-positive breast cancer, meaning the cancer cells have receptors that bind to estrogen. Tamoksifeeni can be used to treat both early-stage and advanced breast cancer. It is also used to reduce the risk of developing breast cancer in women who are at high risk, such as those with a strong family history of the disease or specific genetic mutations.

The medication is typically taken orally as a tablet once a day. Treatment duration can vary, often lasting for several years. Like all medications, tamoksifeeni can have side effects. Common side effects include hot flashes, vaginal discharge or dryness, fatigue, and menstrual irregularities. Less common but more serious side effects can include an increased risk of blood clots, stroke, and uterine cancer. Medical professionals carefully weigh the benefits against the potential risks when prescribing tamoksifeeni. Regular monitoring is essential for patients undergoing treatment.
