Toxicity Profile
Route of ExposureInjestion or inhalation (smoking). L1810
Mechanism of ToxicityBatrachotoxins act on sodium channels by modifying both their ion selectivity and voltage sensitivity. By increasing the permeability of the cell membrane, the cell is depolarized by the influx of sodium. Sodium channels become persistently active at the resting membrane potential and nerve signal transmission to the muscles is blocked. Batrachotoxin also induces a massive release of acetylcholine in nerves and muscles and destroys of synaptic vesicles. (1)

Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesBatrachotoxins are found in poison dart frogs (genus Dendrobates and Phyllobates), Melyridae beetles, and certain birds (genus Pitohui and Ifrita). (1)
Minimum Risk LevelNot Available
Health EffectsBatrachotoxins affect the peripheral nervous system and heart muscles. (1)
SymptomsBatrachotoxins interfere with heart conduction, causing arrhythmias, extrasystoles, ventricular fibrillation and other changes which lead to cardiac arrest. (1)
TreatmentWhile it is not an antidote to batrachotocins, the membrane depolarization can be prevented or reversed by either tetrodotoxin, which is a non-competitive inhibitor, or saxitoxin. These both have effects antagonistic to those of batrachotoxin on sodium flux. Certain anaesthetics may act as receptor antagonists to the action of this alkaloid poison, while other local anaesthetics block its action altogether by acting as competitive antagonists. (1)
