CAS : 112809-51-5
Molecular Formula: C17H11N5
Molecular Weight: 285.31
Molecular Structure:
 
Character: White or light yellow crystal
Usage:  used in the treatment of breast cancer, letrozole is a new generation of aromatase inhibitors, for the artificial synthesis of benzyl three azole derivatives, letrozole by inhibition of aromatase, which decreases the level of estrogen, thereby eliminating the stimulating effect of estrogen on the growth of tumor.

2. Product Description

Femara(generic name is letrozole) is a new drug developed for the treatment of advanced breast cancer in women. Femara is the second in a new class of third-generation selective oral aromatase inhibitors.

It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. Since many forms of breast cancer cells are stimulated by estrogen, it is hoped that by reducing amounts of estrogen in the body the progression of such a disease can be halted. This is the basic premise behind Nolvadex, except this drug blocks the action and not production of estrogen.

3. Applications

The effects of Femara can be quite dramatic to say the least. A daily dose of one tablet (2.5 mg) can produce estrogen suppression greater than 80 % in treated patients. With the powerful effect this drug has on hormone levels, it is only to be used (clinically) by post-menopausal women whose disease has progressed following treatment with Nolvadex. Side effects like hot flushes and hair thinning can be present, and would no doubt be much more severe in pre-menopausal patients.

With the one drug halting estrogen conversion and the other blocking 5-alpha reduction (testosterone, methyltestosterone and Halotestin only), related side effects can be effectively minimized. Here the strong androgen testosterone could theoretically provide incredible muscular growth, while at the same time being as tolerable as nandrolone.
Additionally the quality of the muscle should be greater, the athlete appearing harder and much more defined without holding excess water.
