Clomiphene

Information about Clomiphene

Clomiphene is an oral agent used to treat infertility in women desiring pregnancy.

Liver safety of Clomiphene

Clomiphene has been linked to a low rate of transient serum aminotransferase elevations during therapy and to rare instances of clinically apparent liver injury, which can be severe and even fatal.

Mechanism of action of Clomiphene

Clomiphene (kloe' mi feen) is an orally available, nonsteroidal antiestrogen that stimulates ovulation and is used largely as therapy of infertility in women. Clomiphene interacts with estrogen receptors in many tissues, including the hypothalamus, pituitary, ovary, endometrium, vagina and cervix. The inhibition of estrogen effects by clomiphene leads to release of pituitary follicular stimulating hormone (FSH), which initiates growth and maturation of the ovarian follicle, follicular rupture and ovulation. In clinical trials, clomiphene resulted in pregnancies in approximately 30% of patients.

Clomiphene was approved for use in the United States in 1967, and current indications are for treatment of ovulatory dysfunction in women desiring pregnancy.
