FDA Botox News & Botox Specials with Dr. Mark Bishara, MD
The US Food and Drug Administration (FDA) has approved use of onabotulinumtoxinA (Botox Cosmetic, Allergan) for temporary improvement in the appearance of moderate to severe lateral canthal lines, also known as crow's feet, in adults. Botox Cosmetic is currently the only FDA-approved drug treatment option for lateral canthal lines, the FDA said today.
The agency approved Botox Cosmetic in 2002 for the temporary improvement of glabellar lines (frown lines) in adults. Botox Cosmetic works by keeping muscles from tightening, so wrinkles are less prominent.
Botox Cosmetic is administered via intramuscular injections. Treatment for both frown lines and crow's feet can be given at the same time, the FDA said.
The approval of Botox Cosmetic for treating lateral canthal lines was based on 2 clinical efficacy and safety studies involving 833 adults with moderate to severe lateral canthal lines who were randomly assigned to receive either Botox Cosmetic or placebo.
The results showed that those treated with Botox Cosmetic had greater improvement compared with placebo in the appearance of lateral canthal lines, the FDA said.
