Breast cancer is a complex and multifaceted disease that affects millions of women worldwide. In the realm of breast cancer treatment, aromatase inhibitors have emerged as a crucial class of medications. One such medication is Exemestane 25 mg, a potent aromatase inhibitor used in the treatment of hormone receptor-positive breast cancer. This article aims to provide a comprehensive guide to Exemestane 25 mg, exploring its mechanism of action, benefits, potential side effects, and its role in breast cancer treatment.
What is Exemestane 25 mg?
Exemestane 25 mg is a medication that belongs to the class of aromatase inhibitors. Aromatase is an enzyme responsible for converting androgens into estrogens in the body. In hormone receptor-positive breast cancer, estrogen promotes the growth of cancer cells. By inhibiting aromatase, Exemestane 25 mg effectively reduces estrogen levels, thereby slowing down or stopping the growth of cancer cells.
Mechanism of Action
The mechanism of action of Exemestane 25 mg involves the irreversible inhibition of aromatase. This results in a significant decrease in estrogen production, which is essential for the growth and proliferation of hormone receptor-positive breast cancer cells. By reducing estrogen levels, Exemestane 25 mg helps to control the growth of cancer cells and prevent the progression of the disease.
