Topical a-Agonist Therapy for Persistent Facial Erythema of Rosacea and the Addition of Oxmetazoline to the Treatment Armamentarium: Where Are We Now?

摘要

The presence of vasoactivity in rosacea-affected skin led to the development of two topical α-adrenergic receptor agonists, brimonidine tartrate 0.5% gel and oxymetazoline hydrochloride 1% cream, both approved by the United States Food and Drug Administration for treatment of persistent facial erythema of rosacea. In this article, the author discusses challenges related to the treatment of persistent facial erythema of rosacea and the use of a-agonist therapy. The author also discusses cases of worsening of facial erythema after the application of brimonidine, as well as briefly reviews recently reported clinical data on oxymetazoline. Finally, the author attempts to differentiate some potential mechanistic differences between these two agents.
