| Hepatotoxicity | In clinical trials conducted in children with Wilson disease, serum aminotransferase levels generally improved or were stable during treatment with trientine. There have been no clinical reports of acute liver injury with jaundice attributed to trientine, even with overdoses. Patients with Wilson disease typically have mild-to-moderate serum aminotransferase elevations and may have signs and symptoms of cirrhosis. Improvement in liver injury in Wilson disease typically requires months to years of treatment. |

| Toxizitätsübersicht | While TETA is severely irritating to the skin and eyes and produces skin sensitization, it is of low to moderate acute toxicity orally and dermally. Effects on lungs, liver, and spleen were found in mice in subchronic studies but were not found in rats. While TETA was genotoxic/mutagenic in short-term in vitro assays, it was not genotoxic/mutagenic in in vivo assays. No data on reproductive toxicity were available, and embryo/fetal toxicity was associated with copper deficiency and occurred at maternally toxic doses. The use of TETA·2HCl for treatment of Wilson’s disease during pregnancy in humans resulted in no miscarriages or fetal abnormalities. There was no evidence of carcinogenicity in a lifetime dermal mouse study. |

Anwendungen & Verwendung
Beschreibung
Triethylenetetramine (TETA and trien) also known as trientine (INN) when used medically, is an organic compound with the formula [CH2NHCH2CH2NH2]2. The pure freebase is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air- oxidation. It is soluble in polar solvents. The branched isomer tris(2-aminoethyl)amine and piperazine derivatives may also be present in commercial samples of Triethylenetetramine. The hydrochloride salts are used medically as a treatment for copper toxicity.
Verwenden
Triethylenetetramine is used as an amine hardener in epoxy resin of the bisphenol A type.It is used in synthesis of detergents, softeners, and dyestuffs; manufacture of pharmaceuticals; vulcanization accelerator of rubber; thermo setting resin; epoxy curing agent; lubricating-oil additive; analytical reagent for Cu, Ni; chelating agent; treatment of Wilson's disease.
