- Myobloc
- Generic Name
- Botulinum toxin type B
- DrugBank Accession Number
- DB00042
- Background
Neurotoxin produced by fermentation of clostridium botulinum type B. The protein exists in noncovalent association with hemagglutinin and nonhemagglutinin proteins as a neurotoxin complex. The neurotoxin complex is recovered from the fermentation process and purified through a series of precipitation and chromatography steps.

- Pharmacodynamics
Botulinum Toxin Type B inhibits acetylcholine release at the neuromuscular junction via a three stage process: 1) Heavy Chain mediated neurospecific binding of the toxin, 2) internalization of the toxin by receptor-mediated endocytosis, and 3) ATP and pH dependent translocation of the Light Chain to the neuronal cytosol where it acts as a zinc-dependent endoprotease cleaving polypeptides essential for neurotransmitter release.
- Mechanism of action
Botulinum Toxin Type B binds to and cleaves the synaptic Vesicle Associated Membrane Protein (VAMP, also known as synaptobrevin) which is a component of the protein complex responsible for docking and fusion of the synaptic vesicle to the presynaptic membrane, a necessary step to neurotransmitter release.
Target Actions Organism AVesicle-associated membrane protein 2 binderHumans AVesicle-associated membrane protein 1 binderHumans ASynaptotagmin-2 Not Available Humans - Absorption
Though pharmacokinetic or ADME studies were not performed, Botulinum Toxin Type B is not expected to be present in the peripheral blood at measurable levels following IM injection at the recommended doses.
