The disposition and pharmacokinetics of [(14)C]dimethylamine [(14)C] DMA) following 6-hr inhalation of either 10 or 175 ppm were determined in male Fischer 344 rats. Seventy-two hours after termination of exposure, the disposition of recovered radioactivity was similar for each airborne concentration, with more than 90% in the urine and feces, 7 to 8% in selected tissues and the carcass, and 1.5% exhaled as (14)CO2. Over 98% of the radioactivity in the urine was unmetabolized DMA. Analysis of tissue radioactivity immediately after exposure to [(14)C]DMA showed that the respiratory nasal mucosa contained the highest concentration of (14)C, followed by the olfactory nasal mucosa; concentrations of (14)C in liver, lung, kidney, brain, and testes were approximately 2 orders of magnitude less than in the nasal mucosal tissues. Radioactivity in plasma of rats exposed by inhalation to 175 ppm of [(14)C]DMA decayed in a biphasic manner. The terminal half-life for plasma radioactivity was similar to the half-lives of some plasma proteins, suggesting incorporation of (14)C into proteins subsequent to metabolism of [(14)C]DMA. The results indicate that, while most of the inhaled DMA is excreted unchanged, a small amount of oxidative metabolism of DMA occurs.

1. The fate of [(14)C]-dimethylamine was investigated following oral administration to four male volunteers. 2. The major route of excretion was urine, with 94% of the administered radioactivity being voided over 3 days (87% during the first 24 hr). Small amounts (1-3%) of radioactivity were found in the faeces and expired air. 3. Metabolism was limited with only 5% being demethylated to methylamine. The remainder of the dose was excreted unchanged. 4. Pharmacokinetic studies indicated rapid (t1/2ab = 8 min) and extensive absorption (bioavailability = 82%) from the gastrointestinal tract followed by widespread distribution and a fairly prompt excretion (t1/2el = 6-7 hr) with a plasma clearance of 190 mL/min.

The urinary excretion of dimethylamine has been measured in 203 unrelated healthy volunteers (102 male) who maintained their normal diets. ... The average daily output was 17.43 +/- 11.80 mg (mean +/- SD) (21.21 +/- 14.78 male; 13.74 +/- 5.65 female) with values for the majority of the population lying within the 0.68-35.72 mg range. Four male outliers excreted up to 109.2 mg; these large amounts of dimethylamine were presumed to be of dietary origin. ...

In the gastro-intestinal tract of male Wistar rats fed a commercial diet containing 23.6 ppm dimethylamine (DMA), the concentration of DMA was highest (11.2 +/- 2.1 ppm) in the stomach and declined towards the lower regions. In contrast, the highest DMA concentration (6.6 +/- 2.5 ppm) was observed in the upper small intestine in rats fed a diet containing only 1.0 ppm DMA. DMA was absorbed in the intestines, and the disappearance curves were monoexponential. The t1/2 values for DMA in the ligated stomach, upper and lower small intestine, caecum and large intestine were 198, 8.3, 11.6, 31.5 and 11.0 min, respectively. The DMA concentration in the blood had increased to 3.0 +/- 1.0 ppm (from a pre-injection level of 0.28 +/- 0.06 ppm) 5 min after the injection of 250 micrograms DMA into the ligated upper small intestine. The disappearance curve for DMA in the blood was monoexponential and the t1/2 for the initial 15 min was 12.5 min when 250 micrograms DMA was injected into a femoral vein. The peak concentrations of DMA in the intestine and bile, respectively, were 15.6 +/- 12.6 ppm (at 15 min) and 3.7 +/- 1.9 ppm (at 30 min after the iv injection of DMA). In this 30-min period, urinary DMA increased from 17.3 +/- 9.4 to 139 +/- 23 ppm. These results show that, following ingestion, DMA is absorbed from the intestine into the blood, from which it disappears rapidly, the major part being excreted in the urine while a small proportion is excreted in the bile or secreted into the intestine, where it may be reabsorbed.

It is extensively absorbed (bioavailability 72%); 5% is demethylated to methylene, but 95% is secreted unchanged in the urine.

The intragastric formation of nitrosodimethylamine (NDA) by bacteria existing in the gastrointestinal tract of monkey was examined by determining the in vitro formation of nitrosodimethylamine from nitrite and dimethylamine in the brain-heart-infusion (BHI) medium, adjusted to pH 6 with gastric juice containing 5000 ppm sodium nitrate and 1000 ppm dimethylamine. Nitrosodimethylamine formation depended on the activity of the nitrate-reducing bacteria in the stomach contents of the monkey, and the concn of nitrite was clearly related to the amount of nitrosodimethylamine. NDA was formed in the brain-heart-infusion medium alone at pH 5 and 6. The addition of gastric juice to the medium increased the formation of nitrosodimethylamine.

The extent of nitrosamine formation and the metabolism of the resultant nitrosamines in vivo were investigated by using (15)N-stable isotope labeling and by the determination of the isotope ratio in the expired N. (15)N-labeled dimethylamine (1.1 mmol/kg) and various doses of nonlabeled nitrile (0.55-2.2 mmol/kg) or labeled nitrile without dimethylamine administered to male rats, which were placed in an enclosed respiratory system. The system was flushed with a mixture containing 80% He and 20% O, and N content of the recirculating atmosphere was determined. When labeled dimethylamine and nonlabeled nitrile were administered, nitrile reacted with secondary amines, followed by enzymic alpha-hydroxylation and decomposition of the ensuing alkyldiazohydroxide to molecular N and an alkyl cation as ultimate carcinogen. When (15)N nitrile was administered, N was released (nitrile reacted with primary amines to release molecular N and formation of the corresponding alcohol or olefin).

Dimethylamine is the immediate precursor of dimethylnitrosamine, a known potent carcinogen in a wide variety of animal species. Although small amounts of dimethylamine are ingested directly, the major dietary source is believed to be via choline and related materials. Owing to quantitative recoveries following oral administration, urinary dimethylamine levels provide good overall measures of body exposure. The oral administration of equimolar amounts (1 mmol/kg body weight) of potential amine precursors to male Wistar rats produced only small increases in urinary dimethylamine after choline (+ 11%; 0.60 +/- 0.36% dose), dimethylaminopropanol (+ 32%; 1.49 +/- 0.30% dose), dimethylaminoethyl chloride (+ 110% 5.38 +/- 1.72% dose) and trimethylamine (+ 51%; 1.6 +/- 0.80% dose) input, whereas significantly larger increases were found following trimethylamine N-oxide ingestion (+ 355%; 12.93 +/- 1.13% dose; t-test, P < 0.001). These data suggest that trimethylamine N-oxide is a major dietary source of dimethylamine, by direct conversion and not by sequential reduction (to trimethylamine) and demethylation, and that in this respect it is of greater importance, on a molar basis, than choline.

Uremic toxins tend to accumulate in the blood either through dietary excess or through poor filtration by the kidneys. Most uremic toxins are metabolic waste products and are normally excreted in the urine or feces.
