What is Penicillamine used for?
Penicillamine is used to treat severe and active rheumatoid arthritis (autoimmune disease) in patients who have not responded to conventional therapy. Penicillamine belongs to a group of medicines called disease-modifying antirheumatic drugs (DMARDs). Penicillamine is an immunosuppressant that works by suppressing the activity of the immune system and this helps decrease the symptoms of rheumatoid arthritis such as pain and swelling.
Penicillamine is also classified as a chelating (metal-binding) agent and is used to remove excess copper levels in patients with Wilson's disease, a genetic disorder. In the treatment of Wilson's disease, Penicillamine works by binding to accumulated copper in the body and eliminating it through urine. By reducing copper levels, Penicillamine helps improve the liver function and other conditions caused by the disease such as nerve and mental problems.
Penicillamine is also used to reduce the excretion of cystine in patients with a metabolic disorder known as cystinuria. By decreasing the concentration of cystine in the urine, Penicillamine helps prevent the formation of kidney stones.
Penicillamine may also be used to treat other conditions as determined by your doctor.
