Indication |
Used in the treatment of prostate cancer. Previously used in the
prevention of miscarriage or premature delivery in pregnant women prone
to miscarriage or premature delivery. |
Pharmacodynamics |
Diethylstilbestrol is a synthetic estrogen that was developed to
supplement a woman's natural estrogen production. In 1971, the Food and
Drug Administration (FDA) issued a Drug Bulletin advising physicians to
stop prescribing DES to pregnant women because it was linked to a rare
vaginal cancer in female offspring. |
Mechanism of action |
Estrogens diffuse into their target cells and interact with a
protein receptor, the estrogen receptor. Target cells include the female
reproductive tract, the mammary gland, the hypothalamus, and the
pituitary. The effect of Estrogen binding their receptors causes
downstream increases the hepatic synthesis of sex hormone binding
globulin (SHBG), thyroid-binding globulin (TBG), and other serum
proteins and suppress follicle-stimulating hormone (FSH) from the
anterior pituitary. The combination of an estrogen with a progestin
suppresses the hypothalamic-pituitary system, decreasing the secretion
of gonadotropin-releasing hormone (GnRH). |
