penicillamine

 [pen″ĭ-sil´ah-mēn]
a degradation product of penicillin that chelates certain heavy metals; used orally to reduce the blood copper level in Wilson's disease and to promote excretion of cystine in patients with cystinuria or recurrent cystine renal calculus formation, by helping to solubilize cystine. It is also used as a disease-modifying antirheumatic drug in treatment of refractory rheumatoid arthritis.
