Metabolite Identification
Common NameFormetanate
DescriptionFormetanate, also known as dicarzol or formetanic acid, belongs to the class of organic compounds known as phenyl methylcarbamates. These are aromatic compounds containing a methylcarbamic acid esterified with a phenyl group. Formetanate is a very strong basic compound (based on its pKa). Formetanate is a potentially toxic compound. Contraction of the pupils with blurred vision, incoordination, muscle twitching and slurred speech have been reported. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop. Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma. This compound has been identified in human blood as reported by (PMID: 31557052 ). Formetanate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Formetanate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
