Penicillamine

Penicillamine is a chelating agent and disease-modifying antirheumatic drug (DMARD) that is primarily used to treat Wilson's disease, rheumatoid arthritis, and heavy metal poisoning (such as lead or mercury). It works by binding to excess copper or metals in the body and helping to remove them through urine. In rheumatoid arthritis, it reduces inflammation and slows disease progression. Though effective, Penicillamine requires careful monitoring due to its potential side effects. It is typically prescribed when other treatments are not effective or appropriate.

Uses of Penicillamine

• Treatment of Wilson’s disease (copper buildup in the body)
• Rheumatoid arthritis (when other treatments fail)
• Heavy metal poisoning (lead, mercury, etc.)
• Cystinuria (to prevent kidney stones)

How Penicillamine Works

Penicillamine works by binding to heavy metals like copper or lead and forming stable complexes that are excreted in urine. In autoimmune conditions like rheumatoid arthritis, it reduces inflammation and modulates the immune response, helping to slow joint damage.

Benefits of Penicillamine

• Reduces copper buildup in Wilson’s disease
• Slows progression of rheumatoid arthritis
• Detoxifies the body from harmful metals
• Prevents formation of kidney stones in cystinuria
