Also found in: Dictionary, Thesaurus, Encyclopedia.
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.
A degradation product of penicillin; a chelating agent used in the treatment of lead poisoning, hepatolenticular degeneration, and cystinuria, and in the removal of excess copper in Wilson disease.

penicillamine/pen·i·cil·la·mine/ (pen″ĭ-sil´ah-mēn) a degradation product of penicillin that chelates certain heavy metals and also binds cystine and promotes its excretion; used in the treatment of Wilson's disease, cystinuria, recurrent cystine renal calculi, and rheumatoid arthritis.
A chelating agent, C5H11NO2S, that is a degradation product of penicillin and is used in the treatment of Wilson disease, refractory rheumatoid arthritis, and excess urinary excretion of cystine.
a chelating agent.
indications It is prescribed for the treatment of Wilson's disease and cystinuria and can be prescribed to bind with and remove heavy metals from the blood when there is poisoning resulting from metals such as copper, lead, mercury, arsenic, and gold (succimer is preferred for lead and mercury toxicity). It is also prescribed as a palliative in the treatment of systemic sclerosis (scleroderma) and rheumatoid arthritis when other medications have failed.
contraindications Known hypersensitivity to this drug or penicillamine-related aplastic anemia prohibits its use. It is not given to patients who are pregnant or who have kidney dysfunction.
adverse effects Among the more serious adverse effects are fever, rashes, and blood dyscrasias. Severe bone marrow depression and immune disorders have been associated with long-term use of this drug. d-penicillamine is less toxic than the l form, and much of the reported toxicity is caused by the use of the l or dl form.
