Penicillamine tablets or capsules

What are penicillamine tablets or capsules?

PENICILLAMINE (Cuprimine®, Depen®) helps to treat Wilson's disease (too much copper in the body); rheumatoid arthritis; and iron, mercury, arsenic, or lead poisoning. It can also help to prevent kidney stones. Generic penicillamine tablets and capsules are not yet available.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:
• anemia or other blood disorders
• fever
• kidney disease
• liver disease
• passing blood in urine
• skin or mouth problems
• an unusual or allergic reaction to penicillamine, penicillin, other medicines, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

How should I take this medicine?

Take penicillamine tablets or capsules by mouth. Follow the directions on the prescription label. Swallow the tablets or capsules with a drink of water. Take penicillamine on an empty stomach, at least 1 hour before or 2 hours after food. Do not take your medicine more often than directed. Finish the full course prescribed by your prescriber or health care professional even if the tablets make you feel unwell. Do not stop taking except on your prescriber's advice.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

What if I miss a dose?

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

What drug(s) may interact with penicillamine?

• aluminum salts, like aluminum hydroxide
• antacids
• gold compounds, often used for arthritis
• iron supplements
• magnesium hydroxide (Milk of Magnesia)
• magnesium supplements
• medicines for cancer chemotherapy
• medicines for prevention or treatment of malaria
• medicines that suppress your immune response
• pyridoxine (vitamin B6)

Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking penicillamine?

Visit your prescriber or health care professional at regular intervals to check on your progress. Penicillamine takes some time to work. If you are treating rheumatoid arthritis or Wilson's disease, you may not notice an improvement in your condition for 2 or 3 months. Take your doses regularly and do not stop taking except on your prescriber's advice.

If you are taking penicillamine for Wilson's disease or metal poisoning, you must follow any dietary restrictions given by your prescriber or health care professional. Foods you may need to avoid are those that contain copper (such as chocolate, nuts, liver, and broccoli).

If you are taking penicillamine to prevent kidney stones you need to drink plenty of water. Drink 2 full glasses of water at bedtime and a further 2 full glasses of water during the night.

Penicillamine makes your body need more pyridoxine (vitamin B6). Check with your prescriber or health care professional to see if you need to take extra vitamin B6.

Antacids and iron preparations can stop penicillamine working properly. Check before taking vitamin and mineral supplements; they often contain iron. Avoid taking antacids.

If you are going to have surgery, tell your prescriber or health care professional that you are taking penicillamine.

What side effects may I notice from taking penicillamine?

Side effects that you should report to your prescriber or health care professional as soon as possible:
• black, tarry stools

Routes  ?

Penicillamine is a pharmaceutical of the chelator class. It is sold under the trade names of Cuprimine and Depen. The pharmaceutical form is D-penicillamine, as L-penicillamine is toxic (it inhibits the action of pyridoxine). It is a metabolite of penicillin, although it has no antibiotic properties.

Uses

Penicillamine is used as a form of immunosuppression to treat rheumatoid arthritis. It works by reducing numbers of T-lymphocytes, inhibiting macrophage function, decreasing IL-1, decreasing rheumatoid factor, and preventing collagen from cross-linking.

Penicillamine is also used for treatment of scleroderma.

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.
  • In cystinuria, a hereditary disorder featuring increased cystine excretion, penicillamine binds with the cystine to make it more soluble.
  • Penicillamine has been used to treat mercury poisoning.

History

Dr John Walshe (1956) first described the use of penicillamine in Wilson's disease. He had discovered the compound in the urine of patients (including himself) who had taken penicillin, and experimentally confirmed that it increased urinary copper excretion by chelation. He had initial difficulty convincing several world experts of the time (Drs Denny Brown and Cumings) of its efficacy, as they held that Wilson's disease was not primarily a problem of copper homeostasis but of amino acid metabolism, and that dimercaprol should be used as a chelator. Later studies confirmed both the copper-centered theory and the efficacy of D-penicillamine. Walshe also pioneered other chelators in Wilson's such as triethylene tetramine 2HCl and tetrathiomolybdate (Walshe 2003).
