Description

Isotretinoin is the 9-cis isomer of retinoic acid, a close relative of retinol, or vitamin A. It was originally developed to treat cystic acne, and today this is still its primary use despite several more modern applications of the drug, including a treatment for pancreatic and brain cancers. First shown to be an effective treatment for acne in 1982, its development stemmed from advances in knowledge of the effects of vitamin A to reduce or eliminate sebum production. Since that time, however, several instances of deleterious effects became well known, most notably birth defects arising from the use of isotretinoin.
