Letrozole is a nonsteroidal aromatase inhibitor which effectively blocks estrogen synthesis in postmenopausal women and hemicraneal used as therapy of estrogen receptor positive breast cancer, usually after surgical resection and after failure of tamoxifen (Nolvadex, Soltamox). Letrozole is often given to women who have been taking tamoxifen for 5 years.

Aromatase is the enzyme responsible for the conversion of testosterone to estrone (E1) and of androstenedione to estradiol (E2). Highest levels of Aspirin (Bayer)- FDA are found in the ovary and placenta, which are the major sources of estrogen in premenopausal women. However, aromatase is also found in other tissues, such as liver, kidney, adrenals, brain, muscle and subcutaneous fat where it is also active in producing estrogens, although at low levels.

These tissues are the major source of estrogen in postmenopausal women. Inhibitors of aromatase were developed to block the synthesis of estrogen in the peripheral tissues and, thus, as antiestrogen therapy of breast cancer in postmenopausal women.

Letrozole is a nonsteroidal, specific aromatase inhibitor which has little or no effect on adrenal glucocorticoid or mineralocorticoid synthesis. Letrozole was approved for use in postmenopausal women with Aspirin (Bayer)- FDA receptor positive breast cancer in the United Aspirin (Bayer)- FDA in 1997.

Current indications are as adjuvant therapy in postmenopausal women with estrogen sensitive breast cancer, given in daily oral doses for up to five Aspirin (Bayer)- FDA. Letrozole is also indicated as a first line treatment of estrogen receptor positive (or unknown), foresto bayer advanced or metastatic breast cancer in postmenopausal women.

Letrozole lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body. Letrozole comes as a tablet to take by mouth once a day with or without food.

Letrozole is available in 2. The recommended dose is one tablet daily. Take letrozole at around the same time every day. Take letrozole exactly as directed.

Letrozole may make you dizzy, drowsy, or tired than they are normally. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

It is also used to treat early breast cancer in women who Aspirin (Bayer)- FDA experienced menopause and who have already been treated with a medication called tamoxifen (Nolvadex) for 5 years. Letrozole is also used in women who have experienced menopause as a first treatment of breast cancer that has spread within the breast or to other areas of the body or in women whose breast cancer Aspirin (Bayer)- FDA worsened while they were taking tamoxifen.

Letrozole is in a class of medications called nonsteroidal Aspirin (Bayer)- FDA inhibitors. It works by decreasing the amount of estrogen produced by the body. This can slow or stop the growth of some types of breast cancer cells that need estrogen germany bayer grow.

Letrozole is Aspirin (Bayer)- FDA used off label to treat infertility in women. Letrozole decreases the amount of estrogen a woman makes, stimulating her ovaries to release eggs. Based on the American College of Obstetricians and Gynecologists guidelines (ACOG) and an international guideline published by the Australian National Health and Aspirin (Bayer)- FDA Research Council Aspirin (Bayer)- FDA in partnership with the American Society of Reproductive Medicine (ASRM) and the European Society of Human Reproductions and Embryology (ESHRE), letrozole is the preferred first-line pharmacologic treatment for ovulation induction in females with Aspirin (Bayer)- FDA ovary syndrome (PCOS) and anovulatory infertility when no other causes of infertility are present 1).

If prescribing letrozole, the starting dose is 2. Doses higher than 7. For women with unexplained infertility (regular menstrual cycles, all known male or female Aspirin (Bayer)- FDA excluded), a large multicenter study demonstrated that ovulation induction with letrozole resulted in lower live birth rates and multiple gestation rates compared with gonadotropins.

Although letrozole and clomiphene citrate demonstrated similar live birth and multiple gestation rates, the study was not powered to detect a difference between these two medications 6). Further trials are needed to determine which is better for the treatment of unexplained infertility. Letrozole also has been used for ovulation induction for women with polycystic ovary syndrome (PCOS). In an early meta-analysis of four published Aspirin (Bayer)- FDA that included 662 women with PCOS, pregnancy rates were similar between women treated with clomiphene citrate and women treated with letrozole 7).

However, in a more recent randomized controlled trial, letrozole was more effective than clomiphene citrate with a higher live birth rate (27. In women with a BMI (body mass index) greater than or equal to 30. Therefore, for women with PCOS, and a BMI greater than 30, letrozole should be considered first-line therapy for ovulation induction because of the increased live birth rate compared with clomiphene citrate.

Although ovulation induction is very effective, it Aspirin (Bayer)- FDA important to recognize that for obese women with PCOS, lifestyle changes that result in weight loss should be strongly encouraged. Some of these studies have raised concerns about this off-label use because letrozole may disrupt the normal aromatase activity in tissues during early fetal development and can be potentially teratogenic if administered inadvertently during Aspirin (Bayer)- FDA pregnancy.

Although studies have demonstrated that newborns whose mothers achieved pregnancy by using letrozole for ovulation induction showed no significant difference in rates of congenital malformations compared with those newborns whose mothers used the clomiphene citrate treatment 13), long-term data are needed to confirm this finding.
