Letrozole Mode of Action
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 lowering estrogen levels in the body. Letrozole specifically inhibits the enzyme aromatase, which is responsible for converting androgens into estrogens.
How does Letrozole work?
The mode of action of Letrozole involves blocking the conversion of androgens (such as testosterone) into estrogens. By inhibiting aromatase, Letrozole reduces the amount of estrogen produced in the body. This decrease in estrogen levels can help slow down or stop the growth of hormone receptor-positive breast cancer cells, which rely on estrogen to grow.
Key Points about Letrozole’s Mode of Action:
- Letrozole inhibits the enzyme aromatase: By blocking aromatase, Letrozole reduces estrogen production.
- Reduces estrogen levels: Lower estrogen levels can help in the treatment of hormone receptor-positive breast cancer.
- Slows down cancer cell growth: By depriving cancer cells of estrogen, Letrozole can inhibit their growth and proliferation.

In conclusion, understanding the mode of action of Letrozole is essential for patients and healthcare providers in managing breast cancer treatment. By inhibiting aromatase and lowering estrogen levels, Letrozole plays a crucial role in targeting hormone receptor-positive breast cancer cells. If you have any questions or concerns about Letrozole, it is important to consult with your healthcare provider for personalized advice and guidance.
