The first aromatase inhibitor that was discovered was aminoglutethimide, classified as first-generation AIs. It is still used today despite causing side effects such as lack of target enzyme specificity which also has effects on other cytochrome P450 enzymes . [ 12 ]
[11] [4] In addition, it is described as a much more potent aromatase inhibitor than adrenal steroidogenesis inhibitor. [17] AG can inhibit aromatase by 74 to 92% and decrease circulating estradiol levels by 58 to 76% in men and postmenopausal women. [1] [7] AG is not an effective ovarian steroidogenesis inhibitor in premenopausal women. [17]
Aminoglutethimide inhibits both aromatase and other enzymes critical for steroid hormone synthesis in the adrenal glands. It was formerly used for breast cancer treatment, but has since been replaced by more selective aromatase inhibitors.
Ovarian stimulation with the aromatase inhibitor letrozole has been proposed for ovulation induction in order to treat unexplained female infertility. In a multi-center study funded by the National Institute of Child Health and Development, ovarian stimulation with letrozole resulted in a significantly lower frequency of multiple gestation (i.e., twins or triplets) but also a lower frequency ...
Aromatase inhibitors (AIs) such as aminoglutethimide, anastrozole, exemestane, letrozole, and testolactone inhibit the production of estrogens from androgens and are used mainly in the treatment of estrogen receptor-positive breast cancer.

Steroidal aromatase inhibitors are a class of drugs that are mostly used for treating breast cancer in postmenopausal women. High levels of estrogen in breast tissue increases the risk of developing breast cancer and the enzyme aromatase is considered to be a good therapeutic target when treating breast cancer due to it being involved in the final step of estrogen biosynthetic pathway and also ...
Fadrozole (INN Tooltip International Nonproprietary Name), sold under the brand name Afema (by Novartis), is a selective, nonsteroidal aromatase inhibitor which is or has been used in Japan for the treatment of breast cancer. [1] [2
