Application

Acitretin, a retinoid that binds to nuclear receptors and regulates gene expression, is a potent activator of the α-secretase ADAM10 gene expression and apoptosis inducer via the CD95 signalling pathway. Acitretin is a systemic retinoid drug used in the treatment of severe psoriasis.

Biochem/physiol Actions

Synthetic retinoid that is a metabolite of etretinate. Preferentially binds to cellular retinoic acid binding proteins (CRABPs).

Despite widespread dissatisfaction and low treatment persistence in moderate to severe psoriasis, patients' reasons behind treatment discontinuation remain poorly understood. We sought to characterize patient-reported reasons for discontinuing commonly used treatments for moderate to severe psoriasis in real-world clinical practice.
