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 reducing the levels of estrogen in the body. Understanding the letrozole mode of action can help patients and healthcare providers better grasp how this medication works to combat cancer.
How Does Letrozole Work?
Letrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogen. By blocking this https://letrozole-for-sale.com/medicament/letrozol-heumann-25-mg/ conversion process, letrozole reduces the amount of estrogen in the body, which is crucial in treating hormone receptor-positive breast cancer.

Key Points about Letrozole Mode of Action:
- Aromatase Inhibition: Letrozole blocks the activity of the aromatase enzyme, preventing the conversion of androgens into estrogen.
- Estrogen Reduction: By lowering estrogen levels, letrozole starves hormone receptor-positive breast cancer cells.
- Cancer Cell Death: Deprived of estrogen, cancer cells are unable to grow and multiply, leading to their demise.
