Identification
- Summary
Dienestrol is a non steroidal estrogen used to treat atrophic vaginitis and kraurosis vulvae.
- Generic Name
- Dienestrol
- DrugBank Accession Number
- DB00890
- Background
Dienestrol is a synthetic, non-steroidal estrogen. It is an estrogen receptor agonist. Estrogens work partly by increasing a normal clear discharge from the vagina and making the vulva and urethra healthy. Using or applying an estrogen relieves or lessens: dryness and soreness in the vagina, itching, redness, or soreness of the vulva. Conditions that are treated with vaginal estrogens include a genital skin condition (vulvar atrophy), inflammation of the vagina (atrophic vaginitis), and inflammation of the urethra (atrophic urethritis).

Estrogens diffuse into their target cells and interact with a protein receptor. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. 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. The combination of an estrogen with a progestin suppresses the hypothalamic-pituitary system, decreasing the secretion of gonadotropin-releasing hormone (GnRH).
- Mechanism of action
Dienestrol is a synthetic, non-steroidal estrogen. Estrogens passively diffuse into target cells of responsive tissues, complex with the estrogen receptors, and enter the cell's nucleus to initiate or enhance gene transcription of protein synthesis after binding to DNA.
