Tamoxifen
DESCRIPTION

Tamoxifen is a generic medication which primarily treats breast cancer in women. It is known as a nonsterodial anti-estrogen drug. It is available for oral administration.

How it works

Estrogen is a hormone in females and it plays a key role in the formation and growth of breast cancer cells. Estrogen receptors are found in breast cancer cells. Tamoxifen works by fighting against estrogen to attach with Estrogen receptors. By doing so, this medication is able to inhibit the activity of estrogen in breast cancer cells and prevent or slow down the multiplication of harmful cancer cells. On the other hand, Tamoxifen can increase the positive effects of Estrogen which are linked to other functions in the body. For instance, this drug is a replacement for estrogen and it is known to prevent bone loss. Women who have reached menopause can lower their risks of other illnesses such as osteoporosis without having to use another hormone replacement.

Uses

Aside from treating women, this drug is known to treat breast cancers in men too. Tamoxifen is also prescribed to treat infertility in women and Gynecomastia; a condition in the endocrine system that is responsible for the enlargement of breast tissues in males. In addition, this drug is given to treat persons with the genetic disorder called McCune- Albright Syndrome.
