Mechanism of action of ethyl alcohol in methyl alcohol poisoning is:
Ethanol is the antidote for methyl alcohol poisoning. Methyl alcohol is oxidized to formaldehyde by the enzyme catalase. This catalase can also oxidize ethyl alcohol to acetaldehyde. In methyl alcohol poisoning, ethyl alcohol by competition for catalase, blocks the formation of formaldehyde and allows the less toxic methyl alcohol to be excreted unmetabolized.

Saturate alkaline phosphatase
Blocks formation of formaldehyde
Inhibit Ca release
All of the above
