Medications for Wilson's disease treat this genetic disorder in various ways. They work by reducing the amount of copper in your body, which helps prevent damage to your liver and brain. Common classes include chelating agents and zinc salts. Chelating agents like trientine (Syprine, Cuvrior) and penicillamine (Cuprimine, Depen) bind to copper, allowing your body to excrete it. Zinc salts, such as Galzin (zinc acetate), block your body from absorbing copper from food. These medications are usually taken as oral pills.
