Tamoxifen
Tamoxifen is a selective estrogen receptor modulator with extensive breast-cancer treatment and risk-reduction literature. It is not an aromatase inhibitor. Its effects depend on tissue-specific estrogen receptor signaling, so descriptions such as estrogen blocker are incomplete without explaining why antagonistic activity in breast tissue can coexist with estrogen-like effects elsewhere.

Mechanism & research
- Mechanism
Tamoxifen and active metabolites bind estrogen receptors and alter recruitment of transcriptional coregulators. Receptor subtype, cellular context and cofactor availability influence the resulting gene-expression program. Hepatic metabolism includes CYP2D6- and CYP3A-related pathways that contribute to active metabolites such as endoxifen. This differs mechanistically from reducing estrogen synthesis, and it explains why circulating estrogen concentration alone cannot summarize the drug's tissue effects.
