Strantas contains the active substance fulvestrant, which belongs to the group of estrogen blockers. Estrogens, a type of female sex hormone, may be involved in the development of breast cancer in some cases.

Strantas is used:

  • alone, to treat postmenopausal women with a type of breast cancer called hormone receptor-positive breast cancer, which is locally advanced or has spread to other parts of the body (metastatic), or
  • in combination with palbociclib to treat women with a type of breast cancer called hormone receptor-positive, human epidermal growth factor receptor 2 (HER2) negative breast cancer, which is locally advanced or has spread to other parts of the body (metastatic). Women who have not reached menopause will also be treated with a medicine called luteinizing hormone-releasing hormone (LHRH) agonist.

Strantas may be administered in combination with palbociclib. It is important that you also read the package leaflet for palbociclib. If you have any questions about palbociclib, ask your doctor.
