In cases of ethylene glycol poisoning and its characteristic metabolic acidosis, treatment involves correction of the acidosis, removal of В. 1.5 C. 2.5 D. None of the above. any remaining ethylene glycol and administration of an inhibitor of ADH (ADH, alcohol: NAD+ gxidoreductase), the enzyme that oxidizes ethylene glycol to the organic acids that cause the acidosis. Ethanol (grain alcohol) frequently is the inhibitor given to treat ethylene glycol poisoning; it works by competitively inhibiting ADH. As a competitive inhibitor, ethanol A.
