A GP guide to Botox for neurological conditions
The botulinum toxins, serotypes A-G, are seven neurotoxic proteins produced by bacteria of the genus clostridium.
All types disrupt neurotransmitter release by interfering with the exocytosis of vesicles from neurons.1
Botulinum toxins type A and B have been purposed for medical use in humans.
However, all PBS-subsidised products contain type A toxin: onabotulinumtoxinA (Botox), abobotulinumtoxinA (Dysport) and incobotulinumtoxinA (Xeomin).
