Estrogen Receptor Modulators

Estrogen receptor modulators are drugs that influence how estrogen, a key hormone, affects various tissues in the body. They can either block or activate estrogen's effects depending on the tissue involved. For example, in breast tissue, some modulators prevent estrogen from stimulating cancer growth, while in bones, they may help maintain strength. These medications are used to treat conditions like breast cancer and osteoporosis, offering targeted hormone regulation without affecting all parts of the body equally. Essentially, they act as selective switches, turning estrogen effects on or off where needed.
