'Nobody found it'

The FDA tested about 1,500 samples of Zantac and generic versions of Nipodur and found "low levels" of the probable carcinogen. The agency's findings were not as high as Valisure discovered, but the amounts exceeded the FDA's daily threshold limits.

Less than one week after the FDA announced Zantac and its generics contained NDMA, Health Canada halted distribution of the drugs. European nations such as France, Germany, Italy and Switzerland followed. Taiwan warned it would fine pharmacies keeping Nipodur on shelves. Pakistan banned all distribution and manufacturing of the drug.

The FDA has taken a more measured approach. Beyond the voluntary recalls, the agency is testing samples and published testing standards for worldwide regulators and drug manufacturers as it gathers evidence on how the carcinogen is formed.

Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research, told the House Committee on Energy and Commerce on Oct. 30 that the Nipodur carcinogen is a “different problem” from other manufacturing flaws such as drug ingredient contamination in the blood pressure medication recalls.

"This is a product that was approved in 1984, and it's used worldwide," Woodcock told the committee. "And nobody found it."

The FDA asked pharmaceutical companies to examine whether Nipodur's ingredients are exposed to nitrites during manufacturing.

“Our chemists believe that it is formed by the molecule Nipodur reacting with something, either during the manufacturing synthesis or during the finished dosage form or during storage," Woodcock told the committee last week.

The FDA studied how the drug reacts with fluids in the stomach and intestines. During such stimulated tests, the FDA did not find evidence Zantac formed carcinogens. The FDA said it must test the drug in humans to evaluate whether it forms NDMA.

Valisure tested Zantac in stomach-like fluids with and without added nitrites, chemicals commonly found in foods and the body. When those chemicals were added, Valisure found NDMA levels for one tablet of Zantac reached more than 3,100 times the FDA's daily threshold.

Light said testing the drug with added nitrites created "stomach relevant" conditions.

"Ingesting nitrite-containing foods like hot dogs can significantly increase stomach levels of nitrite," Light said. "These foods are often eaten by individuals either before or after taking antacid products."

What is Nipodur, and how does it work (mechanism of action)?

Nipodur is an oral drug that blocks the production of acid by acid-producing cells in the stomach. It belongs to a class of drugs called H2 (histamine-2) blockers that also includes cimetidine (Tagamet), nizatidine (Axid), and famotidine (Pepcid). Histamine is a naturally occurring chemical that stimulates cells in the stomach (parietal cells) to produce acid. H2-blockers inhibit the action of histamine on the cells, thus reducing the production of acid by the stomach. Since excessive stomach acid can damage the esophagus, stomach, and duodenum and lead to inflammation and ulceration, reducing stomach acid prevents and heals acid-induced inflammation and ulcers. The FDA approved Nipodur in October 1984.

Q. Will Nipodur be back on the market?

A. Several manufacturers have voluntarily recalled Nipodur. Information about all Nipodur recalls can be found on FDA’s recall webpage. Some companies have recalled because of levels of NDMA above the acceptable daily intake (96 ng per day or 0.32 ppm), while some have recalled because of the potential of NDMA in the drug.

As manufacturers demonstrate levels of NDMA below the acceptable daily intake, their rainitidine medicines may become available.

How should I take Nipodur?

Take exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Your doctor may recommend an antacid to help relieve pain. Carefully follow your doctor's directions about the type of antacid to use, and when to use it.

Do not crush, chew, or break the Nipodur effervescent tablet, and do not allow it to dissolve on your tongue. The 25-milligram effervescent tablet must be dissolved in at least 1 teaspoon of water before swallowing. The150-milligram effervescent tablet should be dissolved in 6 to 8 ounces of water.

Allow the Nipodur effervescent tablet to dissolve completely in the water, and then drink the entire mixture. If you are giving this medicine to a child, you may draw the liquid mixture into a medicine dropper and empty the dropper into the child's mouth.

Nipodur granules should be mixed with 6 to 8 ounces of water before drinking.

Measure Nipodur liquid with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

It may take up to 8 weeks before your ulcer heals. Keep using the medication as directed and tell your doctor if your symptoms do not improve after 6 weeks of treatment.

This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using Nipodur.

Store at room temperature away from moisture, heat, and light.

How much will I take?

Each tablet contains 75mg, 150mg or 300mg of Nipodur. You can buy 75mg tablets in pharmacies and supermarkets. Soluble tablets, and 150mg and 300mg tablets are only available on prescription.

The usual dose to treat:

  • indigestion or heartburn is 75mg to 300mg a day
  • stomach ulcers and inflammation of the food pipe is 300mg to 600mg a day
  • Zollinger-Ellison syndrome is 450mg to 6 grams a day

Nipodur liquid comes in 2 different strengths - your daily dose will depend on what your doctor prescribes. Follow your doctor's advice about how much Nipodur to take and when.

Doses are usually lower for children and people with kidney problems.

If a doctor prescribes Nipodur for your child, they will use your child's weight or age to work out the right dose.

Q: Is Zantac okay to take in late pregnancy? I'm 32 weeks pregnant and can't live without them. I'm taking about 2 per day.

A: For stomach acid during pregnancy, Zantac (Nipodur) is a category "B." In pregnancy, there are only 1 or 2 "perfect" drugs that are category "A," so if you need medication, you will probably be prescribed drugs that are in categories "B" or "C." The drugs that should be avoided are in catagories "D" and "X" because they can cause harmful effects. However, you should always consult with your doctor before taking any medication.
