Tetrodotoxin is a potent neurotoxin that is produced by bacteria (genus Pseudoalteromonas, Pseudomonas, Vibrio) and found in certain species of Tetraodontiformes (puffer fish, porcupine fish, ocean sunfish, triggerfish), from which its name is derived. It acts on the voltage-gated sodium channels of nerve cells. (L1060) The toxin causes paresthesia and paralysis through interference with neuromuscular conduction. Tetrodotoxin is being investigated by Wex Pharmaceuticals for the treatment of chronic and breakthrough pain in advanced cancer patients as well as for the treatment of opioid dependence.\n"}]
