Botox more satisfactory, effects last longer than Dysport
Study Findings:
- Patients are significantly more satisfied with their appearance after treatment with BOTOX Cosmetic than with Dysport, a formulation of botulinum toxin type A not yet approved for use in North America.
- The study also demonstrated that effects of treatment with BOTOX Cosmetic last longer than the treatment effects of Dysport.
- Both treatments were well-tolerated.
Method:
- Randomized, double-blind study involving 30 patients up to 55 years of age (mean age, 42) with glabellar lines of at least moderate severity.
- Study participants were randomly assigned to receive BOTOX Cosmetic 20U or Dysport 50U (in five injections, 1 in the procerus muscle and 2 in each of the corrugator muscles). Patient evaluation of satisfaction with appearance was measured on a scale of 0 (not at all satisfied with appearance) to 6 (extremely satisfied with appearance).
- Glabellar line severity was rated by investigators who assessed standardized post-treatment photographs of study participants without knowing which treatment they had received.
