Tamoxifen is classified as a(an).. Thyroid hormone. Antiestrogen

Tamoxifen is classified as a(an):

  • A. Estrogen
  • B. Antiestrogen
  • C. Androsterone
  • D. Testosterone
  • E. Thyroid hormone.

The answer is: B. Antiestrogen

Tamoxifen is a selective estrogen receptor modulator (SERM) that acts as an antiestrogen in breast tissue. This means it blocks the effects of estrogen on breast cells, which can help prevent or treat breast cancer.
Here's why the other options are incorrect:

A. Estrogen:

Tamoxifen actually blocks the effects of estrogen, so it is the opposite of an estrogen.

C. Androsterone:

Androsterone is a type of male sex hormone, while tamoxifen is used to treat breast cancer and is not related to male sex hormones.

D. Testosterone:

Testosterone is another type of male sex hormone, and like androsterone, it is not related to tamoxifen.

E. Thyroid hormone:

Thyroid hormones regulate metabolism and other bodily functions, and tamoxifen does not affect thyroid function.

Therefore, Tamoxifen is classified as an antiestrogen due to its ability to block the effects of estrogen in breast tissue.
