Class Summary

May relax smooth muscle.

OnabotulinumtoxinA (BOTOX®)

Botulinum toxin type A is produced by Clostridium botulinum and is responsible for botulism in humans. Botulinum toxin type A produces denervation of affected muscle tissue by irreversibly binding to presynaptic nerve endings and inhibiting the release of acetylcholine.

When endoscopically injected into the lower esophageal sphincter (LES), interference with cholinergic transmission of the myenteric plexus leads to smooth muscle relaxation with a subsequent fall of the LES resting pressure. This drug has been used in other fields of medicine to treat spastic torticollis and blepharospasm.
