Spotlight on brimonidine topical gel 0.33% for facial erythema of rosacea: safety, efficacy, and patient acceptability

Abstract

Background: Brimonidine tartrate is a highly selective alpha 2 agonist that induces direct vasoconstriction of small arteries and veins, thereby reducing vasodilation and edema.

Objective: To review the current literature regarding the safety, efficacy, and patient acceptability of brimonidine 0.33% gel.

Methods: A PubMed search was performed using the terms brimonidine 0.33% gel, rosacea, safety, efficacy, and acceptability. Peer-reviewed clinical trials and case reports from 2012 to 2016 were screened for inclusion of safety, efficacy, and/or patient acceptability data.

Results: Brimonidine topical gel 0.33% is associated with mild, transient skin-related adverse reactions. Efficacy may be achieved within 30 minutes of administration with maximal reductions in erythema 3-6 hours after administration. Patient satisfaction with use of brimonidine topical gel is superior to vehicle gel for facial appearance, treatment effect, facial redness, and daily control of facial redness.

Limitations: Studies were typically limited to 1-year follow-up. Only one study has examined the use of brimonidine topical gel in combination with other rosacea and acne medications.

Discussion: Brimonidine topical gel 0.33% is a safe, effective, and patient-accepted treatment for facial erythema of rosacea.

Keywords: adverse reactions; patient satisfaction; side effects.
