Tamoxifen 20 Mg – What Exactly Does This Drug Do?

Breast cancer treatments for patients include a wide variety of options like chemotherapy, surgery, and hormone therapy. One of the drugs used for hormone therapy includes the popular drug Nolvadex-D from Astra Zeneca, which contains the active ingredient Tamoxifen Citrate. Tamoxifen products like Nolvadex and their generic counterparts are used alone or in conjunction with the other treatments for breast cancer and may also be used as preventive agents in patients with a history or high risk for breast cancer.

Tamoxifen Uses: What is This Drug?

Tamoxifen 20 mg is termed a hormone receptor antagonist drug or an anti-estrogen product. Products with the active ingredient Tamoxifen Citrate are primarily indicated for patients with breast cancer, often as a standalone treatment or a supplemental treatment for patients who have undergone other medical procedures like radiation or chemotherapy.
The drug Tamoxifen Citrate blocks the growth (metastasis) by blocking the cancer cell receptors for estrogen. Tamoxifen aims to reduce cancer cell growth through this mechanism of action because cancer cells feed on estrogen, hence the blockage of cancer cell receptors for estrogen can halt the tumor growth.
