XEOMIN® 100U powder for solution for injection contains 100 units of incobotulinumtoxin A. Native Botulinum toxin type A is a high molecular weight complex, which, in addition to the toxin (150 kD), contains other bacterial non-toxic proteins, like haemagglutinins and non-haemagglutinins. In contrast to conventional preparations containing the botulinum toxin A complex, Xeomin contains pure (150 kD) toxin since it is free from complexing proteins and thus has a low foreign protein content. The foreign protein content administered is considered as one of the factors for secondary therapy failure. IncobotulinumtoxinA is produced from the fermentation of Clostridium botulinum and is subsequently purified to remove complexing proteins. It consists of the purified neurotoxin which has been separated from complexing proteins (haemagglutinins and a non-toxic non-haemagglutinating protein) during production. A prescription medicine product used to improve the look of moderate to severe frown lines between the eyebrows. Also to treat abnormal head position, neck pain caused by cervical dystonia. Also improves eyelids that have had prior treatment with anabotulinum toxin type A.
