What is fomepizole used for?
Antizol (fomepizole) is an antidote used to treat poisoning with ethylene glycol (antifreeze) or methanol (contained in solvents, fuels, and other household or automotive chemicals). Antizol is sometimes used together with hemodialysis to rid the body of a poison.
When should you not use fomepizole?
Criteria for stopping fomepizole (one of the following): concentration of methanol or ethylene glycol is undetectable. concentration of methanol is below 3.2 mmol/L or ethylene glycol is below 6.2 mmol/L AND the patient is asymptomatic with a normal pH.
Is fomepizole an orphan drug?
At the time of the submission, orphan drug designation was granted fomepizole in the United States for the treatment of methanol and ethylene glycol poisoning. Fomepizole was approved in the United States for the treatment of methanol or suspected methanol poisoning in December 2000.
What is the antidote for methanol?
ANTIDOTE: Fomepizole and ethanol are effective antidotes against methanol toxicity. Fomepizole or ethanol should be administered as soon as possible once the patient/victim has been admitted to a medical care facility.
When should I start taking Fomepizole?
Although no study has compared its efficacy with ethanol, fomepizole is recommended as a first-line antidote. Treatment should be started as soon as possible, based on history and initial findings including anion gap metabolic acidosis, while awaiting measurement of alcohol concentration.
When should I start taking fomepizole?
How can you tell if alcohol has methanol in it?
To test for the presence of methanol, you can apply sodium dichromate to a sample of the solution. To do so, mix 8 mL of a sodium dichromate solution with 4 mL of sulfuric acid. Swirl gently to mix, then add 10 drops of the mixed solution to a test tube or other small container containing the alcohol.
How does ethylene glycol cause kidney failure?
The kidney toxicity of ethylene glycol occurs 24 to 72 hours post ingestion and is caused by a direct cytotoxic effect of glycolic acid. The glycolic acid is then metabolized to glyoxylic acid and finally to oxalic acid.
Is ethylene glycol toxic?
Ethylene glycol is chemically broken down in the body into toxic compounds. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys. Ingestion of sufficient amounts can be fatal.
What is the antidote for ethylene glycol?
If ethylene glycol poisoning is suspected, begin antidotal therapy empirically while awaiting confirmation. Antidotes are fomepizole and ethanol. B-vitamin therapy may be used as an adjunct to antidotal therapy.
What is the molecular formula of Antizol vet?
Antizol-Vet is a synthetic alcohol dehydrogenase inhibitor. It is a 4-methyl-substituted five-membered ring structure with the molecular formula C4H6N2 and a molecular weight of 82.1 grams per mole.
How to liquefy Antizol vet for animal use?
Antizol-Vet is supplied as a sterile concentrate. If the Antizol-Vet solution has solidified in the vial, the solution should be liquefied by running the vial under warm water or holding it in the hand. Solidification does not affect the efficacy, safety, or stability of Antizol-Vet.
What’s the best temperature to store Antizol vet?
Antizol-Vet ® (fomepizole) for injection is supplied as a sterile single-use vial containing 1.5 mL (1.5 g) of Antizol-Vet without excipients. Store at room temperature 15° to 30°C (59° to 86°F).
When to stop giving Antizol vet to dogs?
Fifty percent of the dogs dosed at 20 mg/kg showed some plasma accumulation after 14 days of dosing. In general, dogs dosed below 20 mg/kg should have no detectable fomepizole in their plasma by 12 hours following intravenous dose administration. Antizol-Vet is supplied as a sterile concentrate.
