Tamoxit Tablet 20 mg, a powerful tool in the fight against breast cancer, is primarily composed of Tamoxifen. Operating as a Selective Estrogen Receptor Modulator (SERM), it exerts its therapeutic effects by inhibiting the growth of breast cancer cells through the blocking of estrogen receptors.

Precautions and Consultation

If you are considering Tamoxit Tablet 20 mg for reducing the risk of breast cancer or if your cancer is limited to the milk ducts (ductal carcinoma in situ – DCIS), it is imperative to engage in a comprehensive discussion with your healthcare provider. For individuals with breast cancer that has spread to other parts of the body, the initiation of tamoxifen may lead to increased bone/cancer pain and/or disease flare-up.

Tamoxit Availability

Tamoxit Tablet 20 mg is readily available in packs containing 30 film-coated tablets. However, specific availability may vary based on regional regulations and healthcare provisions.

Mechanism of Action

Tamoxit Tablet 20 mg’s active ingredient, Tamoxifen, exerts its therapeutic prowess by blocking the effects of estrogen on hormone receptor-positive breast cancer cells. It accomplishes this by binding to estrogen receptors on the cells, preventing estrogen from attaching and thus impeding the signals that encourage cancer cell growth and proliferation. Tamoxifen’s classification as a Selective Estrogen Receptor Modulator (SERM) underscores its ability to reduce estrogen’s effects throughout the body, including in the breast.

Onset of Action and Duration

Tamoxit Tablet 20 mg initiates its action immediately after oral administration, but its effects remain active for up to two weeks after the last dose. Peak plasma concentration is typically reached around 5 hours post-dosing. Tamoxifen’s elimination from the body is biphasic, with a terminal elimination half-life of about 5 to 7 days. It can take approximately three months for Tamoxifen to be completely eliminated from the system. This medication is often prescribed for long-term treatment, with optimal effectiveness observed when used for 5 years.

Recommended Dosage

The recommended dosage of Tamoxit Tablet 20 mg varies based on the specific medical condition being treated:

  • Metastatic breast cancer in women and men: Usual adult dose is 20 to 40 mg orally daily for 5 years, with doses exceeding 20 mg administered in divided doses (morning and evening).
  • Ductal Carcinoma in Situ (DCIS) following breast surgery and radiation: Recommended dose is 20 mg orally daily for 5 years.
  • Breast Cancer – Adjuvant: Typical adult dose is 20 mg orally once daily or 10 mg orally twice daily, with treatment duration extending up to 5 years.
  • McCune-Albright Syndrome; precocious puberty in girls aged 2 to 10 years: Standard pediatric dose is 20 mg orally once daily, with therapy spanning up to 12 months.

To maximize the benefits of Tamoxit Tablet 20 mg, it’s advisable to take it at the same time daily. If a dose is missed, there is no need to double up the next day. In the case of doses exceeding 20 mg per day, dividing the dosage between morning and evening is recommended.

Breast Cancer

Breast cancer is a formidable disease characterized by the uncontrolled growth of cells within the breast. Various types of breast cancer exist, typically determined by which cells in the breast undergo malignant transformation. In most cases, breast cancer originates in the ducts or lobules of the breast.

  • Invasive Ductal Carcinoma: This form involves cancer cells originating in the ducts and subsequently infiltrating adjacent breast tissues. Invasive cancer cells can also metastasize to other parts of the body.
  • Invasive Lobular Carcinoma: Cancer cells in this subtype begin in the lobules and may spread to nearby breast tissues. Metastasis to other body parts is also possible.
  • Other Less Common Types: There are rarer forms of breast cancer, including Paget’s disease, medullary, mucinous, and inflammatory breast cancer.
  • Ductal Carcinoma in Situ (DCIS): This is a breast condition that may progress to invasive breast cancer. DCIS involves cancer cells confined to the lining of the ducts and has not spread to surrounding tissues.

Breast cancer can extend beyond the breast through blood and lymph vessels, leading to metastasis. Understanding the specific type of breast cancer is crucial for determining appropriate treatment strategies.

The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
