Acitretin, a beneficial retinoid, was shown to undergo constant structural interconversions among its geometrical isomers (all-trans-acitretin, 9-cis-acitretin, 13-cis-acitretin, 9, 13-di-cis-acitretin, etc.) by photoisomerization under natural light. The photoisomerization was zero order reaction with an apparent velocity of 4x107 M/min under illumination by white fluorescent lamps (1, 200 lx)...

Background: Acitretin therapy is frequently associated with reversible, dose-related side effects. Recent studies claimed that combining vitamin E with high-dose isotretinoin reduced isotretinoin-induced side effects. Objective: The purpose of this clinical trial study was to determine the effect of a fixed or adjusted dose of vitamin E on the side effects of acitretin. Patients and Methods: Fi...

Acitretin, a synthetic retinoid, is a pharmacologically active metabolite of etretinate. It replaced etretinate for the treatment of severe psoriasis (e.g. psoriatic erythrodermia and pustular psoriasis) because of its more favourable pharmacokinetic profile. Acitretin is 50 times less lipophilic than etretinate and has a shorter elimination half-life. However, there is evidence that small amou...

BACKGROUND Lichen planus is an inflammatory disease that affects the skin, the oral mucosa, or both. Generalized cutaneous lichen planus may pose a therapeutic challenge for clinicians if the condition persists or flares after topical or systemic corticosteroid therapy. PURPOSE Acitretin, a systemic retinoid, can be considered a potential second-line treatment for patients with generalized cu...

We assessed the clinical efficacy, tolerability and safety of acitretin in a patient with ichthyosis. A newborn infant with ichthyosis who presented at birth with collodion baby appearance, was treated with acitretin. A moderate response to acitretin therapy (1 mg/kg/day) administered for 6 months was observed, with improvement in cutaneous lesions. Clinical improvement was achieved shortly aft...

Skin cancers are by far the most common human malignancies. Retinoids have shown promising preventive and therapeutic effects against a variety of human malignancies. The aim of this study was to investigate the apoptosis-inducing effect of acitretin on human skin squamous cell carcinoma (SCC) SCL-1 cells. We found that acitretin preferentially inhibited the growth of SCL-1 cells in a dose- and...

INTRODUCTION Two cases of impotence following a treatment with etretinate have been reported in the literature. Acitretin is the principal active metabolite of etretinate. We report a case of erectile dysfunction associated with the use of acitretin. CASE PRESENTATION A 39-year-old Caucasian man referred his incapacity to reach and maintain a penile erection during a course of acitretin for t...

OBJECTIVE To evaluate the effect of compound glycyrrhizin in combination with acitretin on Th17 cell and related cytokines expressions in patients with psoriasis. METHODS A total of 100 patients with psoriasis were enrolled in our study and randomized into an acitretin (Aci) group (n = 50) and a compound glycyrrhizin/acitretin combined treatment (Aci + Glyc) group (n = 50). Both groups were m...

BACKGROUND Etanercept, a soluble tumor necrosis factor receptor, and acitretin have been shown to be effective in treating psoriasis. Acitretin is widely used in Korea. However, the combination of etanercept plus acitretin has not been evaluated among Korean patients with psoriasis. The objective of this study was to investigate the efficacy and safety of combination therapy with etanercept and...

Acrodermatitis continua of Hallopeau (ACH) is considered as a localized form of pustularpsoriasis that is usually refractory to the treatment. The condition is characterized by sterile pustules, onychodystrophy, anonychia, and osteolysis of distal phalanges. The authors report a case of recalcitrant ACH who previously failed to topical corticosteroid, methotrexate, acitretin, and phototherapy a...
