The Mechanism of Action of Anastrozole

The Mechanism of Action of Anastrozole

**Anastrozole**, sold under the brand name Arimidex, 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. Estrogen is a hormone that can fuel the growth of certain types of breast cancer cells. By blocking the production of estrogen, anastrozole helps to slow down or stop the growth of these cancer cells.

Mode of Action

Anastrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens (male hormones) into estrogen (female hormone) in the body. By blocking this conversion process, anastrozole effectively reduces the amount of estrogen circulating in the bloodstream. This reduction in estrogen levels helps to deprive estrogen-sensitive breast cancer cells of the hormone they need to grow and multiply.

Key Points about Anastrozole’s Mode of Action:

  • Aromatase Inhibition: Anastrozole blocks the activity of the aromatase enzyme, preventing the conversion of androgens into estrogen.
  • Estrogen Reduction: By lowering estrogen levels, anastrozole starves estrogen-sensitive cancer cells of their growth stimulus.
  • Selective Targeting: Anastrozole specifically targets estrogen production without affecting other hormones in the body.
  • Long-lasting Effects: Anastrozole’s effects are sustained over time, making it an effective long-term treatment option for hormone-sensitive breast cancer.
