Botulinum toxin type A: new information about an old medicine
Abstract:
Now that several formulations of botulinum toxin type-A (BoNT-A) are on the market in North America and throughout the world, it is of great practical importance for those who administer these medications to be familiar with the differences between the formulations. These differences pertain to the stability of the medications, in particular during the period of time between reconstitution and administration, which may affect the degree of diffusion through various tissues after injection. A variety of relatively new uses of BoNT-A for dermatological conditions will be discussed.
