Local administration of botulinum toxin (BoTx) inhibits presynaptic acetylcholine release. All cholinergically innervated muscles and glands can be paralyzed accordingly. Studies on the application of BoTx in multiple sclerosis have shown good results for focal spasticity, in particular, of the extremities. The first promising data were published on bladder disorders, especially with regard to detrusor sphincter dyssynergia and detrusor hyperreflexia. Hyperhidrosis, hypersalivation and proctologic symptoms might be other areas of application. Approval, however, has been greatly restricted which limits the therapeutic range of use.
