Excerpt

The recent article from Dr Frevert of Merz,[1] together with the accompanying commentary from Dr Sesardic of NIBSC,[2] makes a new contribution to the data available for clinical botulinum toxin type A (BoNT-A) products. However, in addition to the comments about the various technical aspects of the data provided by Dr Frevert, as described by Dr Sesardic,[2] one important and key factor about the BoNT-A products has not been mentioned. The units of each product are different, not interchangeable, and no fixed or established conversion ratio exists between them,[35] regardless of what clinical data are presented. …
