The antidotes for ethylene glycol poisoning are ethanol and fomepizole. This antidotal treatment forms the mainstay of management of ethylene glycol poisoning. The toxicity of ethylene glycol comes from its metabolism to glycolic acid and oxalic acid. The goal of pharmacotherapy is to prevent the formation of these metabolites.
Ethylene glycol, antifreeze, is extremely toxic to dogs. It has a sweet taste and thus dogs will drink it. As little as 2 1/2 tablespoons can kill a medium-sized dog in 2–3 days. This type of poisoning is often fatal as dog owners do not know their pet has ingested the antifreeze. De-icing fluids can also contain ethylene glycol.
Ethylene glycol has relatively high mammalian toxicity when ingested, roughly on par with methanol, with an oral LD Lo = 786 mg/kg for humans. [30] The major danger is due to its sweet taste, which can attract children and animals. Upon ingestion, ethylene glycol is oxidized to glycolic acid, which is, in turn, oxidized to oxalic acid, which is ...
Heparin poisoning Prussian blue: Thallium poisoning: Physostigmine sulfate Anticholinergic poisoning Pyridoxine: Isoniazid poisoning, ethylene glycol, accidental hydrazine exposure (E.G from Gyromitra mushrooms) Phytomenadione (vitamin K) and fresh frozen plasma: Warfarin overdose and some (but not all) rodenticides Sodium bicarbonate
There are several causes of toxic optic neuropathy. [1] Among these are: ingestion of methanol (wood alcohol), ethylene glycol (automotive antifreeze), disulfiram (used to treat chronic alcoholism), halogenated hydroquinolones (amebicidal medications), ethambutol and isoniazid (tuberculosis treatment), and antibiotics such as linezolid and chloramphenicol as well as chloroquine and the related ...
The LD 50 for small mammals is between 2 and 25 g/kg, less toxic than its relative ethylene glycol but still capable of causing toxicity in humans (in high concentrations only). [15] It appears that diethylene glycol may be more hazardous to humans [ 16 ] than implied by oral toxicity data in laboratory animals.
The effect of ethanol on dogs and cats is similar to its effect on humans, also causing intoxication. Death is unlikely given supportive care (only one death is known). Ethanol is also an antidote for ethylene glycol poisoning. [47] Mouse and rat poison, anticoagulant type Rodenticide is commonly found in the house or garage.
The toxic effects of ingesting ethylene glycol occur because it is converted by the liver into 4 other chemicals that are much more toxic. The lethal dose of pure ethylene glycol is 1.4 ml/kg (3 US fluid ounces (90 ml) is lethal to a 140-pound (64 kg) person) but is much less lethal if treated within an hour.
