Letrozole is a potent aromatase inhibitor that plays a critical role in the management of hormone receptor-positive breast cancer, particularly in postmenopausal women. By inhibiting the aromatase enzyme, Letrozole ultimately reduces estrogen levels in the body, which can slow the growth of certain types of breast tumors that require estrogen to grow.
Letrozole tablets are a type of aromatase inhibitor that works by decreasing the amount of estrogen produced in the body. This medication is commonly used in the treatment of hormone receptor-positive breast cancer.

Mechanism of Action
Letrozole works through the following mechanisms:
- Aromatase Inhibition: By preventing the conversion of androgens into estrogens, Letrozole effectively lowers estrogen levels.
- Reduction of Estrogen Availability: With lower estrogen levels, estrogen-sensitive cancers may receive reduced stimulation, which can slow their progression.
- Potential for Tumor Regression: Some tumors may shrink in response to reduced estrogen, improving outcomes for patients.
Clinical Uses
Letrozole is primarily used in the following scenarios:
- Adjuvant treatment for early-stage hormone receptor-positive breast cancer.
- Treatment of metastatic breast cancer in postmenopausal women.
- As a fertility treatment for women with certain types of ovulatory dysfunction.
Conclusion
Understanding the pharmacological action of Letrozole is essential for healthcare professionals and patients alike. As an effective option in the management of hormone receptor-positive breast cancer, Letrozole continues to be a vital medication in oncological therapy.
