Etretinate is a synthetic aromatic retinoid, formerly used for the treatment of severe, recalcitrant psoriasis and other keratinization disorders. Due to its long elimination half-life and teratogenic potential, it has been withdrawn or replaced by acitretin in many countries and is not commonly used today.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers after oral administration.
