Clomiphene citrate is a white to pale yellow, essentially odorless, crystalline powder. It is freely soluble in methanol; soluble in ethanol; slightly soluble in acetone, water, and chloroform; and insoluble in ether. CLOMID is a mixture of two geometric isomers [cis (zuclomiphene) and trans (enclomiphene)] containing between 30% and 50% of the cis-isomer. Each white scored tablet contains 50 m...

to a receptive endometrium suitable for implantation. One of the major drugs used for infertility treatment is clomiphene citrate (a non steroidal synthetic compound with both estrogenic and anti-estrogenic activity). Clomiphene citrate stimulates ovulation by competitively inhibiting the estrogen (E) binding to the hypothalamic estrogen receptors (ER), thereby releasing the hypothalamus from t...

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...
