Letrozole is a medication that belongs to the class of drugs known as aromatase inhibitors. It is commonly prescribed for the treatment of hormone receptor-positive breast cancer in postmenopausal women. Letrozole works by reducing the amount of estrogen produced in the body, which helps to slow down or stop the growth of cancer cells.
Estrogen is a hormone that plays a crucial role in the growth and development of breast cancer cells. In postmenopausal women, estrogen is primarily produced by converting androgens (male hormones) into estrogen through an enzyme called aromatase. Letrozole works by inhibiting this enzyme, thereby decreasing the production of estrogen in the body.
Letrozole is typically administered orally in the form of tablets, and it is usually taken once a day with or without food. The dosage may vary depending on the specific condition being treated and the individual’s response to the medication. It is important to follow the prescribed dosage and schedule recommended by a healthcare professional.
Letrozole is considered an effective treatment option for hormone receptor-positive breast cancer. It is often used as an adjuvant therapy following surgery or other treatments to reduce the risk of cancer recurrence. Additionally, letrozole may be used in advanced or metastatic breast cancer cases where the cancer has spread to other parts of the body.
Like any medication, letrozole can cause side effects. Common side effects include hot flashes, joint pain, fatigue, headache, dizziness, and increased sweating. More serious side effects are rare but may include osteoporosis, liver problems, and cardiovascular issues. It is important to discuss any concerns or side effects with a healthcare professional.
In conclusion, letrozole is a medication that belongs to the class of aromatase inhibitors and is commonly prescribed for the treatment of hormone receptor-positive breast cancer in postmenopausal women. By reducing the production of estrogen, letrozole helps to slow down or stop the growth of cancer cells. It is important to follow the prescribed dosage and consult with a healthcare professional regarding any concerns or side effects.
