Etretinate is a medication used to treat severe psoriasis. It is a synthetic aromatic retinoid. The mechanism of action of etretinate is still incompletely understood although, like retinoic acid, it is thought to interfere with the terminal differentiation of keratinocytes. It is thought to bind to the retinoic acid receptors. Etretinate is also believed to enhance the binding of cAMP to the regulatory RI subunit of cAMP dependent protein kinases. Etretinate was taken off the market in Canada in 1996 and America in 1998 due to the risk of birth defects. Etretinate is now used to treat T-cell lymphomas. It also appears to inhibit NADH oxidase activity.

The mechanism of action of the active metabolite, acitretin, is unknown, however it is believed to work by targeting specific receptors (retinoid receptors) in the skin which help normalize the growth cycle of skin cells.
