Estradiol cypionate is an estradiol prodrug used to treat vasomotor symptoms and hypoestrogenisms from hypogonadism. Estradiol Cypionate is a pro-drug ester of DB00783, a naturally occurring hormone that circulates endogenously within the human body.
- Mechanism
- Curator reviewed
Estradiol enters target cells freely (e.g., female organs, breasts, hypothalamus, pituitary) and interacts with a target cell receptor. When the estrogen receptor has bound its ligand it can enter the nucleus of the target cell, and regulate gene transcription which leads to formation of messenger RNA. The mRNA interacts with ribosomes to produce specific proteins that express the effect of estradiol upon the target cell. Estrogens increase 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.
Increases in the down-stream effects of ER binding reverses some of the symptoms of menopause and of hypoestrogenism, which are primarily caused by a loss of estrogenic activity.
