Exemestane

What is Exemestane?

Exemestane is an oral prescription hormone therapy medicine used mainly in breast cancer treatment for women after menopause. It belongs to a group of medicines called aromatase inhibitors, which help lower estrogen levels in the body. Doctors often prescribe this tablet when previous treatments like tamoxifen are no longer effective. This medicine supports long-term cancer care by slowing tumor growth and reducing the risk of cancer returning.

Exemestane used for

Exemestane is primarily used for the treatment of hormone-receptor-positive breast cancer. It helps:

• Women whose cancer has progressed after tamoxifen

• Women after menopause who need long-term hormonal therapy

• Patients who require estrogen-lowering medications as part of their cancer plan

Chemical composition

The active ingredient is Exemestane, a steroid-based aromatase inhibitor. Inactive ingredients may include microcrystalline cellulose, mannitol, crospovidone, hypromellose, and magnesium stearate.

Exemestane Mechanism

Exemestane works by blocking the enzyme aromatase, which is responsible for converting androgens into estrogen. Since certain breast cancer cells grow faster when estrogen levels are high, this medicine helps stop the cancer from receiving the hormones it needs to grow.

How Does it Support Recovery?

By lowering estrogen levels, Exemestane slows down or stops the growth of hormone-sensitive breast cancer cells. This helps:

• Reduce the risk of cancer spreading

• Prevent cancer from coming back

• Improve treatment response when other therapies fail

• Support overall long-term cancer control

What are the Other Benefits?

Along with managing breast cancer, Exemestane offers several advantages:

• Works even when tamoxifen is no longer effective

• Taken as a simple once-daily tablet

• Often better tolerated than older hormonal therapies

• Helps reduce the chance of tumor recurrence

• Can be part of combination cancer therapy
