Tamoxifen Citrate: Selective Estrogen Receptor Modulator (SERM)

Tamoxifen citrate is a widely used nonsteroidal anti-estrogen agent for the treatment of hormone-dependent breast cancer. Tamoxifen is a prodrug and extensively metabolized by cytochrome P450 (CYP450) enzymes into active metabolites including 4-hydroxytamoxifen and endoxifen (4-hydroxy-N-desmethyltamoxifen). They act as an estrogen receptor antagonist in breast tissue. Tamoxifen is commonly referred to as a selective estrogen receptor modulator (SERM), since it behaves as an estrogen receptor agonist in other tissues. (The product is for research purpose only.)
