 Mechanism of Action

Tamoxifen citrate is a Selective Estrogen Receptor Modulator (SERM). It operates through two primary mechanisms:

1. Estrogen Inhibition: It competes with estradiol for estrogen receptors. By blocking these receptors, it prevents circulating estrogen from expressing its effects in specific tissues.
2. Hormonal Recovery (Post-Cycle): In contexts where natural testosterone is suppressed, Tamoxifen prevents the activation of estrogen receptors, signaling the body to resume the production of androgens (testosterone).

 Usage and Dosage

• Medical Use: Primarily indicated for the treatment of breast cancer in women.
• Alternative Use: Used as an anti-estrogen or for post-cycle therapy (PCT).
• Effective Dose: 100-150 mg/day.
