Penicillamine, sold under the trade names of Cuprimine among others, is a medication primarily used for treatment of Wilson's disease, cystinuria and active rheumatoid arthritis. Penicillamine is a chelating agent recommended for the removal of excess copper in patients with Wilson's disease. From in vitro studies which indicate that one atom of copper combines with two molecules of penicillamine. Penicillamine also reduces excess cystine excretion in cystinuria. This is done, at least in part, by disulfide interchange between penicillamine and cystine, resulting in formation of penicillamine-cysteine disulfide, a substance that is much more soluble than cystine and is excreted readily. Penicillamine interferes with the formation of cross-links between tropocollagen molecules and cleaves them when newly formed. The mechanism of action of penicillamine in rheumatoid arthritis is unknown although it appears to suppress disease activity. Unlike cytotoxic immunosuppressants, penicillamine markedly lowers IgM rheumatoid factor but produces no significant depression in absolute levels of serum immunoglobulins. Also unlike cytotoxic immunosuppressants which act on both, penicillamine in vitro depresses T-cell activity but not B-cell activity.

Sample Use Guides
In all patients receiving penicillamine, it is important that CUPRIMINE be given on an empty stomach, at least one hour before meals or two hours after meals, and at least one hour apart from any other drug, food, or milk.
Wilson's Disease: In the absence of any drug reaction, a dose between 0.75 and 1.5 g that results in an initial
24-hour cupriuresis of over 2 mg should be continued for about three months, by which time the most reliable
method of monitoring maintenance treatment is the determination of free copper in the serum. In patients who cannot tolerate as much as 1 g/day initially, initiating dosage with 250 mg/day, and
increasing gradually to the requisite amount, gives closer control of the effects of the drug and may help to
reduce the incidence of adverse reactions.
Cystinuria:The usual dosage of CUPRIMINE in the treatment of cystinuria is 2 g/day for adults, with a range of 1 to
4 g/day. For pediatric patients, dosage can be based on 30 mg/kg/day. The total daily amount should be divided
into four doses. If four equal doses are not feasible, give the larger portion at bedtime. If adverse reactions
necessitate a reduction in dosage, it is important to retain the bedtime dose.
