TTX, widely distributed among marine as well as terrestrial animals, induces dangerous intoxications. Tetrodotoxin, an Extremely Potent Marine Neurotoxin: Distribution, Toxicity, Origin and Therapeutical Uses. Poisoning from tetrodotoxin is of particular public health concern in Japan, where "Tetrodotoxin may be quantified in serum, whole blood or urine to confirm a diagnosis of poisoning in hospitalized patients or to assist in the forensic investigation of a case of fatal overdosage.
Multidisciplinary Digital Publishing Institute (MDPI) The molecular mystique of tetrodotoxin. Proposed biosynthesis of tetrodotoxin from arginine [49,111].Proposed mechanism of TTX accumulation in marine animals [14].Structures of paralytic shellfish poisons (PSP) toxins.Structure of voglibose (Internal standard for TTX).

For comparison, the oral LD50 of potassium cyanide for mice is 8.5 mg per kg, demonstrating that even orally, TTX is more poisonous than cyanide. San Diego Department of Environmental Health, FDA. TTX was believed to be confined to regions of South East Asia, but recent studies have demonstrated that the toxin has spread to regions in the Pacific and the Mediterranean.

In TTX-derived food poisoning outbreaks, the amount of TTX recovered from suspicious fish samples or leftovers, and residual levels from biological fluids of victims are typically trace. There is a high incidence of tetrodotoxin poisoning occurring in Japan annually.The most common misconception about tetrodotoxin is that is not produced by the pufferfish itself. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvODE4NzYzLXRyZWF0bWVudA== Tetrodotoxin (anhydrotetrodotoxin 4-epitetrodotoxin, tetrodonic acid, TTX) is a potent neurotoxin with no known antidote, which blocks action potentials in nerves by binding to the pores of the voltage-gated, fast sodium channels in nerve cell membranes. Tsujimura K, Yamanouchi K. A rapid method for tetrodotoxin (TTX) determination by LC-MS/MS from small volumes of human serum, and confirmation of pufferfish poisoning by TTX monitoring. 4-Aminopyridine reverses saxitoxin (STX)- and tetrodotoxin (TTX)-induced cardiorespiratory depression in chronically instrumented guinea pigs.

The median lethal dose, or LD50, is around 300 micrograms per kilogram of weight (ug/kg). TTX is extremely toxic. 32 (6):977-83. cit., note, "Despite its long history and a thorough knowledge of its toxicity and pharmacology, neither the pathway to TTX nor even the biogenic origin of TTX is known. TTX, for which there is no known antidote, inhibits sodium channel producing heart failure in many cases and consequently death. TTX poisoning is observed frequently in South East Asian regions. Ohlins TTX 22M Custom (regular doesn’t match), Fox Float X2, DVO Topaz T3 Air.

Tetrodotoxin for prolonged local anesthesia with minimal myotoxicity. 2016 Sep;33(9):1468-89. doi: 10.1080/19440049.2016.1218070.Food Addit Contam Part A Chem Anal Control Expo Risk Assess. Lago J, Rodríguez LP, Blanco L, Vieites JM, Cabado AG. Der Stoff kann oral, inhalativ und ber die Haut aufgenommen werden. The twin tube design allows the gas pressure to always backup the low-pressure side of the piston to keep pressure at a controlled level.

Positive pressure into the airways can overcome the paralysis that comes from a lack of nervous signaling into the lungs. FDA. Most analytical techniques involve mass spectrometric detection following gas or liquid chromatographic separation.Tetrodotoxin has been investigated as a possible treatment for cancer-associated pain. While it isn't likely you'll encounter the purified poison, the toxin is found in seeds of the castor plant.

There is no known antidote to TTX which is a powerful sodium channel inhibitor. However, the prognosis is good when the poisoning is detected early.

This review aims to collect pertinent information available to date on TTX and its analogues with a special emphasis on the structure, aetiology, distribution, effects and the analytical methods employed for its detection. 2015.

There's no antidote to the poison, although it's possible to survive if the dose is small enough.
