Acitretin is an orally bioavailable retinoid that displays anti-inflammatory activity and is used clinically to treat psoriasis. Acitretin is a metabolite of etretinate that displays more optimized pharmacokinetic parameters. This compound activates all retinoic acid receptor subtypes (RARα/β/γ) without binding the receptor itself and also increases cAMP-PKA binding in erythrocytes.
