Quadrosilan (INN Tooltip International Nonproprietary Name, BAN Tooltip British Approved Name) (brand name Cisobitan; former developmental code name KABI-1774) is a synthetic nonsteroidal estrogen that was developed in the 1970s and that is or has been used as an antigonadotropic agent in the treatment of prostate cancer.[1] [2] [3] [4] It is an organosilicon compound, and is also known as 2,6-cisdiphenylhexamethylcyclotetrasiloxane.[3] [5] Quadrosilan has estrogenic activity equivalent to that of estradiol,[6] and can produce feminization and gynecomastia as side effects in male patients.[7] [8]
