For methanol poisoning traetment Ethanol is given because ethanol with enzyme alcohol dehydogenase forms acetic acid and acetaldehyde which is less toxic,Ethanol competes with and slows down the methanol reaction by using up the available alcohol dehydrogenase enzymes allowing the body to excrete the unreacted methanol via urine.This is called \"competitive inhibition\". Antidote therapy, often using ethanol, is directed towards delaying methanol metabolism until the methanol is eliminated from the patient’s system either naturally or via dialysis. Like methanol, ethanol is metabolized by ADH, but the enzyme’s affinity for ethanol is 10-20 times higher than it is for methanol.
