Testolactone (, ) (brand name Teslac) is a non-selective, irreversible, steroidal aromatase inhibitor which is used as an antineoplastic drug to treat advanced-stage breast cancer. The drug was discontinued in 2008 and is no longer available for medical use.
==Medical uses== Testolactone is mainly used for treating various types of breast cancer in women who have been through menopause or whose ovaries no longer function. It works by blocking the production of estrogens, which helps prevent the growth of breast cancers that are stimulated by estrogens. It may also prevent tumor cells from being activated by other hormones. Testolactone has also been used to postpone precocious puberty because of its ability to block estrogen production. In addition, it has been used in the treatment of gynecomastia.
