Tamoxifen Citrate (Tamoxon) 10 mg

Tamoxon (Tamoxifen Citrate) 10 mg is Utinon's selective oestrogen receptor modulator, supplied as 100 tablets. Tamoxifen blocks oestrogen at the receptor rather than reducing production. Each box is sealed and carries a scratch-off authenticity code inside.

What Tamoxon 10MG Is

Tamoxifen citrate is a non-steroidal selective oestrogen receptor modulator. It competes with oestradiol for the oestrogen receptor and acts as an antagonist in breast tissue, while having mixed agonist activity elsewhere. A box holds 100 tablets at 10 mg, for 1,000 mg total. The 10 mg unit is half the common 20 mg clinical strength.

The History of Nolvadex

Tamoxifen was developed in the 1960s and approved in the 1970s as Nolvadex for breast cancer. It became the first targeted endocrine therapy for the disease and was later studied for chemoprevention. Its receptor-blocking mechanism made it a standard comparator for every SERM that followed, and it remains one of the most prescribed endocrine agents in oncology.

How It Works

Tamoxifen binds the oestrogen receptor and prevents oestradiol from activating it in sensitive tissue. Because it does not lower oestrogen production, circulating levels remain unchanged. It is metabolised in the liver into active metabolites, including endoxifen, which have higher receptor affinity. Clearance is slow, with a terminal half-life measured in days. The balance of antagonist and agonist activity varies by tissue.

What the Research Shows

• Tamoxifen was the first targeted endocrine therapy approved for breast cancer.
• Its active metabolites have higher oestrogen receptor affinity than the parent drug.
• Long-term follow-up has characterised bone and endometrial effects.
• It is the reference SERM against which newer modulators are compared.

Research Context

Tamoxifen is the reference SERM. Research has focused on how tissue-specific antagonist and agonist activity can be separated, which is the idea behind newer modulators such as toremifene. The liver conversion to endoxifen is a major source of variability between individuals. That variability is one reason tamoxifen remains an active research subject decades after approval, and it is why metabolite studies are still part of the standard literature.

Strength, Pack and Authentication

Each tablet contains 10 mg of tamoxifen citrate, and the box holds 100 tablets. The carton is printed and tamper-evident, stating the compound, strength and tablet count. A scratch-off security code inside the box links the pack to Utinon's manufacturing records, and the blister format keeps every tablet protected from moisture and light until it is used.
