Will galzin dissolve and remove the already accumulated copper in the brain or is it only effective controlling the further accumulation of copper?  

Galzin. What is the alternative generic name for this medicine?
Further accumulation. Galzin is zinc acetate. The zinc results in the production of a copper binding protein by the absorption cells in the intestines. This protein binds copper and decreases the amount of copper from your diet that gets absorbed. It also prevents the reabsorption of copper that gets into the intestines from saliva, bile, and gastric acid. Bound copper is then removed from the body in feces.
