Compositions, methods and devices for preparing less painful Botulinum toxin formulations
First Claim
1. A device comprising at least two chambers, wherein a first chamber comprises an acidic solution of Botulinum toxin, and a second chamber comprises an acid-neutralizing solution, wherein the acid-neutralizing solution is present in an amount sufficient to raise the pH of the acidic botulinum toxin solution to from about pH 7.0 to about pH 7.5 after mixing.

Abstract
Devices, methods and kits are disclosed for preparing and administering less-painful formulations of Botulinum toxin. The devices, methods and kits of the present invention are comprised of or use an acidic formulation of Botulinum toxin, or, in certain embodiments, a freeze- or flash-dried composition of Botulinum toxin, having a long shelf-life which is subsequently mixed with an acid-neutralizing solution and, optionally a sequestration agent prior to administration to a patient in need thereof. The pH-neutralized formulation of Botulinum toxin is pharmaceutically acceptable for administration to a patient and is significantly less painful than acidic formulations of Botulinum toxin or formulations of Botulinum toxin having unnecessary antigens.
