Mechanism of Action
Tamoxifen citrate is a Selective Estrogen Receptor Modulator (SERM). It operates through two primary mechanisms:
- Estrogen Inhibition: It competes with estradiol for estrogen receptors. By blocking these receptors, it prevents circulating estrogen from expressing its effects in specific tissues.
- 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.
