5.2 Absorption, Distribution and Excretion

/N,N-DIMETHYLACETAMIDE/ ... READILY ABSORBED THROUGH SKIN ... .

Patty, F. (ed.). Industrial Hygiene and Toxicology: Volume II: Toxicology. 2nd ed. New York: Interscience Publishers, 1963., p. 1834


N,N-dimethylacetamide is rapidly absorbed through biological membranes.

PMID:3530639 Kennedy GL Jr; Crit Rev Toxicol 17 (2): 129-82 (1986)


No correlation between personal airborne exposure and excretion of mono-methylacetamide in urine was detected during a full workshift (5 days). Most (n = 6) workers studied (n = 8) excreted about 13% of the calculated inhaled dose as metabolite in urine.

PMID:3681500 Borm PJ et al; J Occup Med 29 (11): 898-903 (1987)


DMAC is readily absorbed in man after oral, dermal, or inhalation exposure. ... About 2% of a dose of dimethylacetamide is recovered in the urine as MMAC /N-methylacetamide/ after inhalation; 10% is recovered after inhalation plus skin exposure. Exposure to 10 ppm of DMAC results in complete excretion of MMAC with in 30 hr. Maximal concns of 45 & 100 ppm (mg/L) of MMAC in the urine are found in subjects exposed both by inhalation & skin. In workers continuously exposed to DMAC vapor (inhalation plus skin) & subjected to DMAC airborne levels of 6-22 ppm ..., about 13.5% of the estimated dose is excreted as MMAC in the urine. Some workers may excrete about 30% of a dose as MMAC.

5.3 Metabolism/Metabolites

The Chemical Society. Foreign Compound Metabolism in Mammals Volume 3. London: The Chemical Society, 1975., p. 429


ANALYSIS OF HUMAN URINE AFTER OCCUPATIONAL EXPOSURE TO DIMETHYLACETAMIDE SHOWS N-METHYLACETAMINE. /FROM TABLE/

Doull, J., C.D. Klaassen, and M. D. Amdur (eds.). Casarett and Doull's Toxicology. 2nd ed. New York: Macmillan Publishing Co., 1980., p. 707


Gas chromatographic analysis of the urine of rats which had received dimethylacetamide by the subcutaneous route indicated the presence of N-methyl-acetamide and acetamide. Both metabolites were also found ... in incubation mixtures of dimethylacetamide with rat liver homogenate. N-Methylacetamide was detected in the urine of human volunteers who had inhaled dimethylacetamide or absorbed dimethylacetamide vapor through the skin. Measurement of the amount of the metabolite N-methylacetamide excreted by individuals exposed to dimethylacetamide vapors with or without face masks which allowed the inhalation of air free of dimethylacetamide indicated that more dimethylacetamide was absorbed through the lung than through the skin. ... Only 2-10% of the amount of dimethylacetamide inhaled was recovered in the urine in the form of N-methylacetamide. It has been suggested that the major urinary metabolite of the analogous dimethylformamide is N-(hydroxymethyl)-N-methylformamide and not N-methylformamide, since the carbinolamide decomposes on the gas chromatography column (to N-methylformamide) but is relatively stable in aqueous solution. In analogy, it would be logical to assume that the N-methylacetamide found in the urine after exposure to dimethylacetamide really arose from chemical breakdown of N-(hydroxymethyl)-N-methylacetamide during the analytical process.

Snyder, R. (ed.). Ethel Browning's Toxicity and Metabolism of Industrial Solvents. 2nd ed. Volume II: Nitrogen and Phosphorus Solvents. Amsterdam-New York-Oxford: Elsevier, 1990., p. 144


N,N-dimethylacetamide is metabolized by demethylation first to monomethyl derivatives and then to the parent acetamide.
