penicilamina

Penicillamine is a medication used to treat a variety of conditions, including Wilson's disease, rheumatoid arthritis, cystinuria, and lead poisoning. It is a chelating agent, meaning it can bind to heavy metals and help remove them from the body.

In Wilson's disease, a genetic disorder characterized by excessive copper accumulation, penicillamine works by binding to copper in the liver and other tissues, facilitating its excretion from the body. This helps prevent liver damage and neurological problems associated with the disease.

For rheumatoid arthritis, penicillamine is considered a disease-modifying antirheumatic drug (DMARD). It works by suppressing the immune system's overactivity, which is responsible for the inflammation and joint damage seen in rheumatoid arthritis. Its exact mechanism in this context is not fully understood but is thought to involve modulation of immune cell function and collagen synthesis.

Penicillamine is also used to manage cystinuria, a condition where excessive amounts of the amino acid cystine are excreted in the urine, leading to kidney stone formation. By binding to cystine, penicillamine helps to break down and solubilize cystine crystals, preventing stone formation.

In cases of lead poisoning, penicillamine's chelating properties are utilized to bind to lead, promoting its removal from the body.

Penicillamine is administered orally. Like many medications, it can have side effects, which may include skin rashes, loss of taste, nausea, and bone marrow suppression. It is important to be monitored by a healthcare professional while taking this medication.
