Rosacea represents a chronic inflammatory dermatosis of uncertain pathophysiology. There are several associated risk factors and the need for long-term treatment is well recognized. This diverse disease is frequently difficult to manage and has a significant impact on quality of life. There are several topical and oral treatments available, of which azelaic acid 15% gel (Finacea) is the first new treatment for rosacea in more than a decade. Azelaic acid per se has multiple modes of action in rosacea, but an anti-inflammatory effect achieved by reducing reactive oxygen species appears to be the main pharmacological action. Clinical studies have shown that azelaic acid 15% gel is an effective and safe first-line topical therapeutic option in patients with mild-to-moderate papulopustular rosacea. Significant continuous improvement in the number of inflammatory lesions and in erythema has been shown over a period of 15 weeks. Adverse effects associated with azelaic acid 15% gel are mostly mild or transient and do not usually necessitate discontinuation of therapy.
