Wilson's illness, a genetic condition that results in an accumulation of extra copper in the body, is treated with trientine powder. The said illness affects the liver and other organs and can cause serious health issues if neglected. In this drug the active compound is trientine dihydrochloride which functions as a copper-chelating agent. It works by building a stable combination with copper in the body, which may then be eliminated through the urine. This aids in lowering copper levels and stopping further copper build-up. Trientine powder is administered along with other drugs and dietary changes as part of a whole treatment programme for Wilson's disease.
