Does Increasing the Dose of Abobotulinumtoxina Impact the Duration of Effectiveness for the Treatment of Moderate to Severe Glabellar Lines?

Abstract

The 120 units of abobotulinumtoxinA were significantly effective in reducing glabellar lines in subjects with Grade 2 (Moderate) wrinkles at baseline for a longer duration than the reported 85 days in the FDA Phase III randomized, placebo-controlled clinical studies using a standard 50 unit dose. Subject satisfaction was high. There was no increase in the incidence of adverse events with this higher dose. J Drugs Dermatol. 2016;15(12):1544-1549.
