Abstract:
Since the commercial launch of Dysport in 1991, after 10 years of clinical studies on its predecessor formulations, this BTX-A product has shown great therapeutic promise with a good safety profile and low incidence of treatment failures. As with all BTX products, Dysport should not be seen as a generic equivalent but as a specific product with individual unit dosing requirements and side effect profiles. Its role as an important BTX-A molecule looks set to expand as new indications for botulinum toxin arise, and as the cosmetic usage of Dysport is approved in countries outside of South America.
