Antizol is indicated as an antidote for ethylene glycol (such as antifreeze) or methanol poisoning, or for use in suspected ethylene glycol or methanol ingestion, either alone or in combination with hemodialysis
Fomepizole is a competitive inhibitor of alcohol dehydrogenase, the enzyme that catalyzes the initial steps in the metabolism of ethylene glycol and methanol to their toxic metabolites. Ethylene glycol is first metabolized to glycoaldehyde which then undergoes further oxidation to glycolate, glyoxylate, and oxalate. Glycolate and oxalate are primarily responsible for metabolic acidosis and renal damage seen in ethylene glycol toxicity. {01}{03} Methanol is first metabolized to formaldehyde and then undergoes subsequent oxidation via formaldehyde dehydrogenase to become formic acid. It is formic acid that is primarily responsible for the metabolic acidosis and visual disturbances that are associated with methanol poisoning.
Antidotes
Agents counteracting or neutralizing the action of POISONS. (See all compounds classified as Antidotes.)
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)

Absorption
Rapid and complete
Route of Elimination
In healthy volunteers, only 1-3.5% of the administered dose of Antizol (7-20 mg/kg oral and IV) was excreted unchanged in the urine, indicating that metabolism is the major route of elimination. In humans, the primary metabolite of Antizol is 4-carboxypyrazole (approximately 80-85% of administered dose), which is excreted in the urine. The metabolites of Antizol are excreted renally.
Volume of Distribution
0.6 to 1.02 L/kg
Primarily hepatic. the primary metabolite is 4-carboxypyrazole (approximately 80 to 85% of an administered dose). Minor metabolites include 4-hydroxymethylpyrazole and the N -glucuronide conjugates of 4-carboxypyrazole and 4-hydroxymethylpyrazole.
The plasma half-life of Antizol varies with dose, even in patients with normal renal function, and has not been calculated.
Antizol (fomepizole) is a competitive inhibitor of alcohol dehydrogenase. Alcohol dehydrogenase catalyzes the oxidation of ethanol to acetaldehyde. Alcohol dehydrogenase also catalyzes the initial steps in the metabolism of ethylene glycol and methanol to their toxic metabolites.
