4 Drug and Medication Information
4.1 Therapeutic Uses

(VET): Ethoxyquin is added to animal feeds at 0.015% as an antioxidant ... to help prevent encephalomalacia in growing chickens.

Booth, N.H., L.E. McDonald (eds.). Veterinary Pharmacology and Therapeutics. 5th ed. Ames, Iowa: Iowa State University Press, 1982., p. 1096


(VET): SANTOQUIN HAS BEEN SUCCESSFULLY USED WITH VITAMIN E IN TREATMENT OF WHITE MUSCLE DISEASE IN LAMBS.

Garner's Veterinary Toxicology. 3rd ed., rev. by E.G.C. Clarke and M.L. Clarke. Baltimore: Williams and Wilkins, 1967., p. 286


Vitamin E and also several synthetic antioxidants, such as ... ethoxyquin, have modified tumor induction by certain carcinogens in a number of target organs. However, inhibition was achieved at high doses at which induction of biotransformation enzymes also occurs with the synthetics and, therefore, inhibition may not be due solely to antioxidant effects.

Amdur, M.O., J. Doull, C.D. Klaasen (eds). Casarett and Doull's Toxicology. 4th ed. New York, NY: Pergamon Press, 1991., p. 152


4.2 Minimum/Potential Fatal Human Dose

3= MODERATELY TOXIC: PROBABLE ORAL LETHAL DOSE (HUMAN) 0.5-5 G/KG; BETWEEN 1 OZ & 1 PINT (OR 1 LB) FOR 70 KG PERSON (150 LB).

5 Pharmacology and Biochemistry
5.1 Absorption, Distribution and Excretion

FEEDING TRIAL IN COWS WAS CONDUCTED TO DETERMINE WHETHER ETHOXYQUIN OR ITS RESIDUES ARE TRANSFERRED FROM FEED TO MILK WHEN ADDED TO COW FEED AT 0.015% OF DRY MATTER INTAKE. LESS THAN 7 UG ETHOXYQUIN/L WAS DETECTED IN MILK BY FLUORIMETRY & BY THIN-LAYER CHROMATOGRAPHY.

PMID:5669931 DUNKLEY WL ET AL; J DAIRY SCI 51 (8): 1215-8 (1968)


(14)C-ETHOXYQUIN WAS DISTRIBUTED THROUGHOUT MOST TISSUES & BLOOD AT 0.5 HR AFTER ADMIN TO RATS. HIGHEST RADIOACTIVITY THROUGHOUT EXPERIMENT WAS OBSERVED IN LIVER, KIDNEY, GI TRACT & ADIPOSE TISSUE. THERE WAS NO ACTIVITY IN CNS. OF DOSE INGESTED BY RAT 2.2 & 0.2% WERE FOUND IN LIVER AT 0.5 HR & 6 DAYS RESPECTIVELY FOLLOWING DOSE. HEPATIC PEAK IN RADIOACTIVITY WAS MEASURED AT 8 HR; & AFTER 6 DAYS 7.5% OF THIS LEVEL WAS STILL PRESENT IN LIVER. 6 DAYS AFTER ADMIN TO RATS RESIDUES OF ETHOXYQUIN & METABOLITES WERE PRESENT IN KIDNEY CORTEX, INTESTINES, LUNG, VARIOUS ADIPOSE TISSUES & BLOOD.

SKAARE JU, NAFSTAD I; ACTA PHARMACOL TOXICOL 44 (4): 303-7 (1979)


The compound is readily absorbed, metabolized, and excreted in urine and feces.

Gosselin, R.E., R.P. Smith, H.C. Hodge. Clinical Toxicology of Commercial Products. 5th ed. Baltimore: Williams and Wilkins, 1984., p. II-406


Ethoxyquin residue levels in the mouse tissue were determined by the HPLC-fluorometric detection method. Mice were given powdered feed containing 0, 0.125, and 0.5% ethoxyquin hydrochloric acid and the ethoxyquin residue levels in liver kidney, lung, and brain tissues were determined after 2, 4, 6, 10, and 14 wk (4 mice/group). The tissue samples were homogenized in 10 volumes (w/v) of acetonitrile-water (7:3 v/v) centrifuged and the supernatants were stored in a freezer for 2-3 hr or until the two layers separated; then the clear upper layers were analyzed. The mean ethoxyquin residue levels in the tissue ranged 0.84-4.58 ug ethoxyquin/g liver and 0.11-0.92 ug ethoxyquin/g brain. The relative weight of the liver (5.21-7.07% body weight) and the hepatic glutathione level (5.99-7.83 uM GSH/g tissue) of mice that received ethoxyquin were significantly higher than those of the controls (4.67-5.05% body weight and 4.30-5.78 uM GSH/g tissue, respectively). The mean hepatic mitochondrial glutathione levels of the higher ethoxyquin feeding group following dietary administration of ethoxyquin for 14 wk, was approximately twofold (1.68 nM GSH/mg protein) of both the control and the lower ethoxyquin feeding groups (0.83 and 0.74 nM GSH/mg protein, respectively.

PMID:2051496 Kim HL; J Toxicol Environ Health 33 (21): 229-36 (1991)


5.2 Metabolism/Metabolites

MAJOR METABOLIC REACTION WAS DEETHYLATION OF ETHOXYQUIN WHICH PRODUCED 6-HYDROXY-2,2,4-TRIMETHYL-1,2-DIHYDROQUINOLINE & 2,2,4-TRIMETHYL-6-QUINOLINE. OTHER REACTIONS WERE HYDROXYLATION TO FOUR DIFFERENT HYDROXYLATED METABOLITES & ONE DIHYDROXYLATED METABOLITE.

PMID:532214 SKAARE JU, SOLHEIM E; XENOBIOTICA 9 (11): 649-57 (1979)


An avg of 28 & 36% of dose of radioactivity was recovered in bile in 12 & 24 hr respectively following intragastric admin of (14)C-ethoxyquin to bile duct cannulated rats. Biliary radioactive substances included, in addn to unchanged ethoxyquin...8-hydroxyethoxyquin; hydroxylated 8-hydroxyethoxyquin; 6-ethoxy-2,2,4-trimethylquinolone; hydroxylated 6-ethoxy-2,2,4-trimethyl-8-quinolone; 6-ethoxy-2,4-dimethylquinoline; and 2,2,4-trimethyl-6-quinolone.
