Abstract
Botulinum neurotoxin type A (BTX-A) weakens voluntary muscle power and is an effective therapy for focal dystonia, including cervical dystonia (CD) and benign essential blepharospasm (BEB). Antibody formation against BTX-A may lead to failure of treatment. NT 201 (XEOMIN®) is a formulation of pure BTX-A that is free of complexing proteins and therefore may have a reduced immunogenic potential in comparison with other BTX-A preparations. In clinical trials, NT 201 was found to be effective, well-tolerated and at least noninferior to a BTX-A preparation containing complexing proteins in the treatment of CD and BEB. There were no differences between the two therapies in terms of onset of action, duration and waning of effect. Future research is aimed at evaluating the benefits of NT 201.
