    Tamoxifen how it works


    Tamoxifen, also known by the brand name Nolvadex, is one of the more commonly prescribed medications to prevent breast cancer recurrence, and when used appropriately, may reduce the risk of recurrence (of breast cancer coming back) by roughly 50 percent. The drug may also be used to reduce the chance that a woman will develop breast cancer in the first place, or to slow the growth of metastatic breast cancer. Tamoxifen works by binding to estrogen receptors on breast cells so that estrogen can't bind and stimulate growth. Learn about the potential side effects, how drug interactions may occur, and how tamoxifen differs from aromatase inhibitors. estrogen-like effects, depending on the particular type of tissue in the body where it acts. It is classified as a selective estrogen receptor modulator (SERM) along with the medication Evista (raloxifene). Tamoxifen is usually not considered beneficial for those who have estrogen or progesterone negative breast cancer. Tamoxifen is a hormonal therapy drug used to treat breast cancer, womb cancer and sometimes other cancers and conditions.

    In the last three decades, thousands of women with breast cancer have taken the drug tamoxifen, only to discover that the therapy doesn’t work, either because their tumors do not respond to the treatment at all, or because they develop resistance to it over time. Now researchers at the University of California, San Francisco (UCSF) have discovered the molecular basis for tamoxifen resistance and found a potential way to defeat it. 13, 2011, at the AACR-NCI-EORTC International Conference: Molecular Targets and Cancer Therapeutics, UCSF oncologist Pamela Munster, MD, and her colleagues will present the results of clinical studies and laboratory experiments that show how some tumors resist tamoxifen and how this resistance can be overcome by administering a second class of drugs.“Understanding the mechanism of tamoxifen resistance and how to defeat it may help a large number of women with hormone-resistant breast cancer,” said Munster. “It may lead quickly to new, more effective treatment strategies and may help to identify biomarkers to help to gauge whether or not someone will respond to treatment in the first place.”The results will be presented at a press conference at a.m. (PST) in room 2004 of the Moscone Convention Center in San Francisco. The National Cancer Institute estimates that more than 200,000 Americans are diagnosed with breast cancer every year. It is the second leading cause of cancer death among American women, claiming more than 40,000 lives in 2009 alone. About 65 percent of women with breast cancer have tumors that, when examined in biopsies, show signs of co-opting a naturally occurring molecule in the human body called the estrogen receptor. Around eight in every 10 breast cancers diagnosed in the UK are classified as ‘oestrogen receptor-positive’ (or ER positive for short). The cancer cells in ER-positive tumours contain large quantities of a protein called the oestrogen receptor. This means the tumours grow in response to the female hormone, oestrogen, which circulates in a woman’s bloodstream. Being dependent on oestrogen gives ER-positive cancers an Achilles heel: it makes them sensitive to drugs like tamoxifen, which block oestrogen from affecting cancer cells. Tamoxifen works like a broken key in a lock – it sticks to the oestrogen receptor, preventing the normal ‘key’ (oestrogen) from fitting anymore, thereby stopping the tumour in its tracks. Its precision targeting of ER-positive breast cancer cells in this way mean it is, in effect, a ‘targeted treatment’. Since its approval in the UK in 1972, tamoxifen’s effectiveness and affordability have earned it a place on a global stage – it appears on the World Health Organisation’s list of essential drugs for the treatment of breast cancer in both developing and developed countries.

  3. Tamoxifen is an antineoplastic nonsteroidal selective estrogen receptor modulator SERM. Tamoxifen competitively inhibits the binding of estradiol to estrogen receptors, thereby preventing the receptor from binding to the estrogen-response element on DNA. The result is a reduction in DNA synthesis and cellular response to estrogen.

    Amoxicillin is an antibiotic that might be prescribed for the treatment of a tooth infection or abscess where the causal organism is a bacterium. This Health Hearty write-up provides information on the uses, side effects, and the correct dose of amoxicillin for tooth infection. Dental caries, tooth infection, and dental abscess are commonly reported dental problems that could affect people of all age groups. Poor dental hygiene is often the contributing factor for these dental problems. If one doesn't brush or floss teeth regularly, bacteria can multiply and act on the food debris that remains lodged between the teeth. At times, the tooth structure gets damaged due to trauma. Under such circumstances, the bacteria can travel through the openings in the damaged tooth to the living pulp tissue, thereby causing an infection.

    Zoloft (sertraline) is a selective serotonin reuptake inhibitor (SSRI) which helps correct the imbalance of serotonin in the brain. Zoloft is commonly prescribed for depression, panic disorder, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD). However, it can also be given to IBS patients, usually in lower doses than those given to depressed patients. The most common side effects of Zoloft are constipation, anxiety, dizziness, drowsiness, dry mouth, loss of appetite, nausea, stomach upset and vomiting. I was diagnosed with IBS when I was 18 after three months of horrible tests and dead ends. I was reluctant to accept the diagnosis, but I had spent the last three months in bed with cramps, nausea, diarrhea and constipation and I had become very depressed (although I was in denial about my depression). My doctor prescribed 50mg of Zoloft (half a tablet first, then a full 50mg). I was still hesitant but went with the regimen, and within a month I was back to normal, started college, got engaged, and moved to a new house.
