tcsc2577 Clomiphene (citrate)

Clomifene Citrate is a selective estrogen receptor modulator.

Target: Estrogen Receptor/ERR

Clomifene Citrate(CC) acted as an estrogen antagonist regardless of the concentration of E2 added together. In conclusion, CC acts as an estrogen agonist/antagonist via ER alpha in a coexisting estrogen concentration-dependent way whereas it acts as an estrogen antagonist via ER beta whether or not estrogen is present [1]. Clomiphene was effective in increasing pregnancy rate compared to placebo (OR 5.8, 95% CI 1.6 to 21.5) as was clomiphene plus dexamethasone treatment (OR 9.46, 95% CI 5.1 to 17.7) compared to clomiphene alone. A significant improvement in the pregnancy rate was reported for clomiphene plus combined oral contraceptives versus clomiphene alone. No evidence of a difference in effect on pregnancy rate was found with any of the other comparisons [2].
