Anwendungsgebiete:

Clomiphene citrate is indicated for the treatment of ovulatory dysfunction in women desiring pregnancy. Impediments to achieving pregnancy must be excluded or adequately treated before beginning clomiphene citrate therapy. Those patients most likely to achieve success with clomiphene therapy include patients with polycystic ovary syndrome (see WARNINGS : Ovarian Hyperstimulation Syndrome ), amenorrhea-galactorrhea syndrome, psychogenic amenorrhea, post-oral-contraceptive amenorrhea, and certain cases of secondary amenorrhea of undetermined etiology. Properly timed coitus in relationship to ovulation is important. A basal body temperature graph or other appropriate tests may help the patient and her physician determine if ovulation occurred. Once ovulation has been established, each course of clomiphene citrate should be started on or about the 5th day of the cycle. Long-term cyclic therapy is not recommended beyond a total of about six cycles (including three ovulatory cycles). (See DOSAGE AND ADMINISTRATION

CLINICAL PHARMACOLOGY
ACTION
Clomiphene citrate is a drug of considerable pharmacologic potency.
With careful
selection and proper management of the patient, clomiphene citrate has
been
demonstrated to be a useful therapy for the anovulatory patient
desiring pregnancy.
Clomiphene citrate is capable of interacting with
estrogen-receptor-containing tissues,
including the hypothalamus, pituitary, ovary, endometrium, vagina, and
cervix. It may
compete with estrogen for estrogen-receptor-binding sites and may
delay replenishment
of intracellular estrogen receptors. Clomiphene citrate initiates a
series of endocrine
events culminating in a preovulatory gonadotropin surge and subsequent
follicular
rupture. The first endocrine event in response to a course of
clomiphene therapy is an
increase in the release of pituitary gonadotropins. This initiates
steroidogenesis and

folliculogenesis, resulting in growth of the ovarian follicle and an
increase in the
circulating level of estradiol. Following ovulation, p
