Metabolite Identification
Common NameAcitretin
DescriptionAcitretin is only found in individuals that have used or taken this drug. It is an oral retinoid effective in the treatment of psoriasis. It is the major metabolite of etretinate with the advantage of a much shorter half-life when compared with etretinate. [PubChem]The mechanism of action of acitretin is unknown, however it is believed to work by targeting specific receptors (retinoid receptors such as RXR and RAR) in the skin which help normalize the growth cycle of skin cells.
