    Glossary Estrogen Receptor Antagonist

    blocks estrogen from activating its cellular receptors

    An Estrogen Receptor Antagonist, also known as an Estrogen Blocker or ER Antagonist, is a substance that binds to estrogen receptors on cells and prevents estrogen from exerting its effects. This can be useful in treating conditions like hormone-sensitive cancers, such as certain types of breast cancer, by inhibiting the growth-promoting effects of estrogen on these cancer cells.
