Source-derived summary

Penicillamine, sold under the brand name of Cuprimine among others, is a medication primarily used for the treatment of Wilson's disease. It is also used for people with kidney stones who have high urine cystine levels, rheumatoid arthritis, and various heavy metal poisonings. It is taken by mouth.

Penicillamine was approved for medical use in the United States in 1970. It is on the World Health Organization's List of Essential Medicines.

Medical uses

It is used as a chelating agent:

In Wilson's disease, a rare genetic disorder of copper metabolism, penicillamine treatment relies on its binding to accumulated copper and elimination through urine. Succimer (dimercaptosuccinic acid) is increasingly used in place of penicillamine.

Penicillamine was the second line treatment for arsenic poisoning, after dimercaprol (BAL). It is no longer recommended.

In cystinuria, a hereditary disorder in which high urine cystine levels lead to the formation of cystine stones, penicillamine binds with cysteine to yield a mixed disulfide which is more soluble than cystine.

Editorial summary

Begin with the source’s own compact description: “Penicillamine” is chemical compound. The dossier treats that line as a proposition to test through Penicillamine, chemical and compound, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1970—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Penicillamine, chemical and compound is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q421239. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1970.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

Three-step research path

  1. Establish the record: confirm the title “Penicillamine”, its source revision and the description used here.
  2. Expand the search: follow Penicillamine primary sources, Penicillamine archive and Penicillamine research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
