| Description | 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. |
| Indication/Disease | To treat patients with cervical dystonia to reduce the severity of abnormal head position and neck pain associated with cervical dystonia. |
| 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 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. |
| Toxicity | One unit of Botulinum Toxin Type B corresponds to the calculated median lethal intraperitoneal dose (LD50) in mice. |
| Metabolism | NA |
| Absorption | Botulinum Toxin Type B is not expected to be present in the peripheral blood at measurable levels following IM injection at the recommended doses as pharmacokinetic or ADME studies were not performed |
