After a small clinical study, researchers say that a new anti-wrinkle drug may work better for treating crow's feet than the well-known drug, Botox. Researchers assert that Dysport, a drug by Medicis Pharmaceutical Corp, performed better during a study.
Back in 2002, the U.S. approved Botox for the use of treating wrinkles commonly found on the face. In 2009, Dysport was approved for the same purpose. Both drugs operate similarly by blocking nerve impulses once injected and are comprised of botulinum toxin. When the drugs are injected by a plastic surgeon, wrinkles become less apparent.
The recent clinical trial was conducted at the Maas Clinic and consisted of 90 patients. The participants were injected with one drug on the right side and another drug on the left side of their faces. Then, researchers were asked to assess the results by using a five point scale. The researchers felt that when it came to the treatment of crow's feet, Dysport performed better when muscles were flexed.
However, the results are limited in scope because no data was compiled to see how the drugs performed when muscles were resting.
