Anastrozole (Anastron) 0.5 mg

Anastron (Anastrozole) 0.5 mg is Utinon's reversible aromatase inhibitor, supplied as 100 tablets. Anastrozole is the active compound in Arimidex and works by blocking the conversion of androgens to oestradiol. Each box is sealed and carries a scratch-off authenticity code inside.

What Anastron 0.5MG Is

Anastrozole is a non-steroidal, type II aromatase inhibitor. It binds the aromatase enzyme reversibly and with high affinity, interrupting the conversion of androstenedione and testosterone into oestrone and oestradiol. A box holds 100 tablets at 0.5 mg, for 50 mg total. The 0.5 mg unit is half the common 1 mg clinical strength, which allows finer adjustment.

The History of Arimidex

Zeneca developed anastrozole and approved it in 1995 under the Arimidex name for advanced breast cancer in postmenopausal women. The ATAC programme later compared it with tamoxifen in early disease and reported better disease-free survival, which moved aromatase inhibitors into first-line use. It is now one of the most studied endocrine agents in oncology.

How It Works

Aromatase converts androgens to oestrogens in fat, muscle and other peripheral tissues. Anastrozole occupies the enzyme binding site and blocks that step, lowering oestrogen production. The pituitary can respond with increased gonadotropin output. Absorption is reliable, hepatic metabolism dominates clearance, and the terminal half-life runs to roughly two days. Because inhibition is competitive, enzyme activity returns once the drug clears.

What the Research Shows

• ATAC established anastrozole's advantage over tamoxifen in early breast cancer.
• Standard doses produce sustained falls in circulating oestradiol.
• Long-term follow-up has tracked bone mineral density and lipid changes.
• Reversible inhibition is the key pharmacological contrast with exemestane.

Research Context

Anastrozole is a common comparator when new aromatase inhibitors are studied because its reversible kinetics are easy to model. Researchers have examined how far oestradiol must fall before bone turnover accelerates, and how quickly enzyme activity recovers after the drug is stopped. Those questions matter in any long-term oestrogen-control design, and they are why anastrozole remains a reference compound. The 0.5 mg tablet is useful where a smaller adjustment is wanted than the 1 mg clinical unit allows.

Strength, Pack and Authentication

Each tablet contains 0.5 mg of anastrozole, 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.
