Understanding Letrozole: What Is It?
Letrozole, a medication primarily used in the treatment of breast cancer, has gained significant attention in both medical and patient communities. This article explores letrozole what is, its uses, mechanism of action, and important considerations for patients.
What Is Letrozole?
Letrozole is an aromatase inhibitor that helps lower estrogen levels in the body. It is often prescribed for postmenopausal women with hormone receptor-positive breast cancer. By reducing the amount of estrogen, letrozole can help slow or stop the growth of certain types of breast tumors that require estrogen to grow.
Uses of Letrozole
- Treatment of hormone receptor-positive breast cancer in postmenopausal women
- Adjuvant therapy after surgery to reduce the risk of cancer recurrence
- Neoadjuvant therapy to shrink tumors before surgery
- Fertility treatments for women with ovulatory dysfunction
How Does Letrozole Work?
The primary action of letrozole is to inhibit the aromatase enzyme, which is responsible for converting androgens into estrogens in postmenopausal women. By blocking this conversion, letrozole effectively reduces estrogen levels in the blood, which can lead to the following effects:
- Slowing the growth of estrogen-dependent tumors
- Reducing the size of existing tumors
- Decreasing the likelihood of cancer recurrence
Potential Side Effects
Like any medication, letrozole can cause side effects. Common side effects include:
- Hot flashes
- Joint pain
- Fatigue
- Nausea
- Bone thinning (osteoporosis)
Important Considerations
Before starting treatment with letrozole, patients should discuss the following with their healthcare provider:
- Medical history, particularly regarding heart disease and osteoporosis
- Current medications to avoid potential interactions
- Pregnancy status, as letrozole is not indicated for use during pregnancy
