Penicillamine is primarily used to treat severe rheumatoid arthritis, Wilson's disease, and cystinuria. It functions as a disease-modifying anti-rheumatic drug (DMARD) in rheumatoid arthritis, reducing inflammation and joint damage. In Wilson's disease, it chelates excess copper, facilitating its excretion. Its clinical relevance lies in managing autoimmune disorders and metal toxicity. In summary, Penicillamine is crucial for treating specific conditions involving copper accumulation and autoimmune processes.
Penicillamine chelates heavy metals, facilitating their renal excretion, and modulates the immune response by inhibiting T-cell activation.
