Dysport, sold by MRX and Ipsen in cosmetic and non-cosmetic indications, respectively, continues to be a minor player in the US neurotoxin market. According to AGN’s 3Q10 CC, Botox has an 84% share of US cosmetic procedures and a 91% (!) share of US dollar sales, despite Dysport’s having been on the market for about two years. In non-cosmetic indications, Dysport’s US share continues to be de minimis.
