Description:
Femara is a type of hormone therapy drug used to treat breast cancer in women who have had their menopause. It is also called Femara.
Femara lowers the levels of the female sex hormone oestrogen in the body. Oestrogen stimulates some breast cancers to grow. These breast cancers are called hormone sensitive or hormone receptor positive. Femara can stop or slow the growth of these cancers. It can also reduce the chance of a breast cancer coming back after surgery.
Femara only works in women who have had their menopause. It is a type of drug called an aromatase inhibitor. After the menopause, women don't produce oestrogen from their ovaries. But they still produce a small amount by using an enzyme called aromatase which turns other sex hormones called androgens into oestrogen. This change happens mainly in fatty tissue, muscle and the skin. Aromatase inhibitors block aromatase so that it can't change the androgen into oestrogen.
Application:
Femara is a non-steroidal aromatase inhibitor (lowers estrogen production) used to treat breast cancer in postmenopausal women. It is often given to women who have been taking tamoxifen (Nolvadex, Soltamox) for 5 years. Femara is available in generic form. Common side effects of Femara include hot flashes, hair loss, joint/bone/muscle pain, tiredness, unusual sweating or night sweats, nausea, diarrhea, dizziness, trouble sleeping, drowsiness, weight gain, weakness, flushing (warmth, redness, or tingly feeling), headache, constipation, numbness/tingling/weakness/stiffness in your hand or fingers, or pain in your hand that spreads to your arm, wrist, forearm, or shoulder.
Usage:
Letrozoles has a 2-4 day half-life, and it needs to be taken for up to 60 days to get a steady blood plasma level, using Letrozolesat such a low dose does happen to make it a very good economic choice compared with other aromatase inhibitors.
