Exemestane (Aromasin) Description:
Exemestane (trade name Aromasin) is a drug used to treat breast cancer. It is a member of the class of drugs known as aromatase inhibitors. Some breast cancers require estrogen to grow.
Those cancers have estrogen receptors (ERs), and are called ER-positive. They may also be called estrogen-responsive, hormonally-responsive, or hormone-receptor-positive. Aromatase is an enzyme that synthesizes estrogen.
Aromatase inhibitors block the synthesis of estrogen. This lowers the estrogen level, and slows the growth of cancers.
Exemestane (Aromasin) Function:
Treating advanced breast cancer in women who are past menopause and whose disease has progressed after treatment with other medicines.
It is also used in the treatment of early breast cancer in certain women who are past menopause and after treatment with other medicines. It may also be used for other conditions as determined by your doctor.
Exemestane is an aromatase inhibitor. It works by stopping the production of estrogen, which may decrease the size and growth of the tumor.

Exemestane (Aromasin) Dosage:
In a therapeutic setting to treat breast cancer, Aromasin is only used after Nolvadex has failed. This is normally after 2-3 years of Nolvadex therapy. From here Aromasin is given to the patient at a dose of 25mg per day, which will normally last another 2-3 years or until the cancer’s progression has come to a halt. This is normally followed by more Nolvadex therapy in an effort to halt the cancer from returning. This is a highly successful plan in the fight against breast cancer.
In a performance setting, standard Aromasin doses will normally be 12.5-25mg every other day. Most should be fine with 12.5mg every other day, with some getting by with only two to three doses per week. The individual’s total sensitivity and the composition of the steroid in cycle in question will dictate the final outcome. There will be, however, some who require a daily dose with as much as 25mg per day.
