Acitretin

Acitretin represents a systemic retinoid medication that healthcare professionals prescribe for severe skin conditions. It derives from vitamin A and targets disorders resistant to other therapies. Acitretin normalises skin cell growth and reduces inflammation effectively.

Acitretin Class

Acitretin belongs to the acitretin class of second-generation systemic retinoids. This acitretin class distinguishes itself through enhanced potency and reduced toxicity compared to first-generation counterparts. Clinicians value its role in dermatological management.

Acitretin Classification

Experts classify acitretin as a monoaromatic retinoid within the broader retinoid family. Its classification emphasises aromatic ring structures that enhance receptor binding. This positions acitretin firmly in advanced therapeutic categories for hyperproliferative skin diseases.

Acitretin Mechanism of Action

Acitretin's mechanism of action involves these key processes:

• Binds to retinoic acid receptors (RARs) in the nucleus.

Modulates gene transcription to regulate cell differentiation, proliferation, and apoptosis.
Inhibits keratinocyte hyperproliferation.
Normalises epidermal differentiation.
Exerts anti-inflammatory effects by downregulating pro-inflammatory cytokines.
Restores skin barrier function through these combined actions.

Acitretin Structure

The acitretin structure features a central cyclohexene ring linked to a polyene chain and an aromatic carboxylic acid moiety. This configuration specifically, (all-trans-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethyl-1-(1,1-dimethyl ethyl)-2,4,6,8-nonatetraenoic acid) confers high affinity for RARs. Its lipophilic nature enables systemic absorption and tissue distribution.

Acitretin Uses

For the treatment of severe psoriasis in adult patients (excluding females of childbearing potential).
