Botulinum toxin in the treatment of autonomic nervous system disorders

Botulinum toxin A has become a valuable tool in the treatment of neurological disorders and other disorders associated with acetylcholine such as excessive muscle contraction and hypersecretion of glands. It is the most potent neurotoxin, and over the past 20 years it has been shown to be very effective in many fields. As such, cholinergic autonomic parasympathetic and postganglionic nerve synapses may be treated with botulinum toxin in conditions involving excessive activity such as hyperhydrosis, Frey's syndrome, hyperlacrimation, and sialorrhea.
