Tamoxifen (Nolvadex®) is a medication in pill form that has been used for more than 25 years to treat breast cancer in women and men. Tamoxifen is one of the most common endocrine therapy drugs. It has been shown to decrease the chance of recurrence in some early-stage breast cancers and to prevent the development of cancer in the opposite breast. Tamoxifen can also slow or stop the growth of cancer cells present in the body. There are an estimated 29 million women at increased risk for breast cancer in this country, and tamoxifen may offer another alternative to watchful waiting or prophylactic (preventative) mastectomy. Tamoxifen is classified as a selective estrogen receptor modulator (SERM) and works as an anti-estrogen: While the hormone estrogen promotes the growth of breast cancer cells, tamoxifen works by blocking estrogen from attaching to estrogen receptors on these cells. By blocking the estrogen receptors, it is believed that the growth of the breast cancer cells will be halted. buy doxycycline shanghai Tamoxifen and raloxifene have been shown to reduce the risk breast cancer, but they can have their own risks and side effects. Tamoxifen and raloxifene are the only drugs that are approved in the US to help lower the risk of breast cancer, although for some women, drugs called aromatase inhibitors might be an option as well. This means that they act against (or block) estrogen (a female hormone) in some tissues of the body, but act like estrogen in others. Estrogen can fuel the growth of breast cancer cells. Tamoxifen can be taken whether or not you have gone through menopause, but raloxifene is only approved for post-menopausal women. Both of these drugs block estrogen in breast cells, which is why they can be useful in lowering breast cancer risk. To lower the risk of breast cancer, these drugs are taken for 5 years. The effect of these drugs on breast cancer risk has varied in different studies. When the results of all the studies are taken together, the overall reduction in risk for these drugs is about 40% (more than a third). These drugs lower the risk of both invasive breast cancer and ductal carcinoma in situ (DCIS). Although a medicine that cuts your risk by about 40% sounds like it must be a good thing, what it would really mean for you depends on how high your risk is in the first place (your baseline risk).

Tamoxifen citrate is also being studied in the treatment of other types of cancer. More About Tamoxifen Citrate. Definition from the NCI Drug Dictionary - Detailed scientific definition and other names for this drug. does propecia regrow hairline Tamoxifen Nolvadex is a medication used to treat hormone-receptor positive early and metastatic breast cancers and to reduce breast cancer risk in undiagnosed women at higher-than-average risk of developing breast cancer. Learn more about tamoxifen. Tamoxifen is used for both women and men who have metastatic breast cancer that is estrogen receptor positive and who are not resistant to the drug. Tamoxifen may also be used as a preventive therapy in women who have an elevated risk of developing breast cancer. In this setting, it can reduce a women's risk of developing breast cancer by half. In 2006, the large STAR clinical study concluded that raloxifene is equally effective in reducing the incidence of breast cancer, but after an average 4-year follow-up, although the difference was not statistically significant, there were 36% fewer uterine cancers and 29% fewer blood clots in women taking raloxifene than in women taking tamoxifen. Tamoxifen improves fertility in males with infertility by disinhibiting the hypothalamic–pituitary–gonadal axis (HPG axis) via ER antagonism and thereby increasing the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and increasing testicular testosterone production. It is taken as a preventative measure in small doses, or used at the onset of any symptoms such as nipple soreness or sensitivity. Other drugs are taken for similar purposes such as clomifene and the anti-aromatase drugs which are used in order to try to avoid the hormone-related adverse effects. Occasionally tamoxifen is used in treatment of the rare conditions of retroperitoneal fibrosis A report in September 2009 from Health and Human Services' Agency for Healthcare Research and Quality suggests that tamoxifen, raloxifene, and tibolone used to treat breast cancer significantly reduce invasive breast cancer in midlife and older women, but also increase the risk of adverse side effects. Some cases of lower-limb lymphedema have been associated with the use of tamoxifen, due to the blood clots and deep vein thrombosis (DVT) that can be caused by this medication. Resolution of the blood clots or DVT is needed before lymphedema treatment can be initiated. For many people living with life-limiting and life-threatening diseases like cancer, medical cannabis has long been hailed as a gift, both for symptom control and for its potential to limit the disease process itself. N., a Hospice and Oncology Nurse who is a fierce patient advocate with a passion for investigating and educating about the evidence surrounding cannabis and cancer, recently broke down some of the most recent evidence and issues in a recent interview. But especially in the case of breast cancer—or, more accurately, breast cancers—the therapeutic potential of cannabis also comes laden with the potential for harm, and, like all medications, patients need to understand that powerful drugs can create unanticipated interactions with other powerful drugs. “New and emerging research from the past several years reveals that tamoxifen, and other Selective Estrogen Receptor Modulators, or SERMS, bind not only to estrogen receptors. They also bind with high affinity to one or both cannabinoid receptors, for CB1 and CB2,” said Wohlschlagel. “Tamoxifen apparently binds to both receptors, as what is called an ‘inverse agonist.’ The possible effects caused by that binding are just beginning to be explored.’” Unlike most forms of cancer, “breast cancer” is actually a blanket term rather than a single diagnosis. It covers several distinct types of cancer that are further distinguished by diagnostic laboratory tests. The specific diagnosis drives individual considerations among patients and their medical teams regarding which treatments are most likely to produce the optimal outcomes for each patient. Tamoxifen is the oldest and most widely used of a class of drugs called Selective Estrogen Receptor Modulators (SERMS).
