Knockoffs on the Pharmacy Shelf
Counterfeit drugs are coming to America
The FDA is overwhelmed by the sheer number of medications flooding into America from abroad.
In 1999, according to Forrester Research, Americans bought $158 million in drugs over the Internet, a convenience that is clearly accompanied by risks. In investigations at Washington Dulles International Airport in Virginia and Oakland International Airport in California, customs and FDA officials found that about 10 percent of the drugs they analyzed--including medications to treat Parkinson's disease, asthma, and osteoporosis--contained no active ingredients. In other cases, counterfeits have included dangerous, even life-threatening, ingredients: The fake Nutropin AQ, for instance, contained human insulin.
Controlling a problem of this scope has so far eluded both customs and the FDA. Agents who recently conducted an inspection at a mail facility in Los Angeles were faced with 16,000 parcels of pharmaceuticals in just one month. Of those, FDA inspectors were able to examine only 721 parcels, and because of budget and manpower restraints, they were not able to chemically analyze any of the drugs. This was true even though most of the 721 parcels contained controlled substances, lacked a prescription, were outdated, or were suspected of being counterfeit. "[T]he system is inadequate and incapable of protecting the public from potentially adulterated and unsafe medicines," Congress warned the FDA in a letter in March.
Profit potential. Experts fear that counterfeit drugs will proliferate as drug prices continue to soar. The most recent counterfeit cases have focused on highly expensive drugs: Serostim costs $21,000 for a 12-week dose, and Neupogen, used by chemotherapy patients, costs between $150 and $250 per vial. "If someone was to produce a truckload of this stuff," says Amgen spokesman David Kaye, "it could be quite lucrative." Indeed, the industry estimates that it loses $2 billion each year to counterfeiting.
With so much at stake, drug makers routinely check wholesalers and others to ensure that the products they supply are genuine. "These people are screened upside down and every which way," says Ken Allard, director of pharmacy development at Rite Aid. "There is no way we would buy anything that was even suspect." But the technology used to counterfeit drugs has become so sophisticated that it is often hard to distinguish the genuine medication from the fakes.
In February, Los Angeles authorities arrested three people for running a counterfeit Viagra operation so sophisticated that a Pfizer analysis of the product ranked it a nine out of a possible 10. "They had the lot numbers, the package inserts, the packaging," says Monette Cuevas, the Los Angeles County Department of Health Services pharmacist who examined the drugs. "You could not tell the difference."
In an attempt to curb the counterfeit problem, some drug companies have put chemical tags into their medications so they can check a vial with equipment resembling a home pregnancy test. And the FDA has recently provided its field inspectors with an electronic database to help them visually compare genuine medications against suspected counterfeits. In the meantime, consumers are wise to buy their drugs from familiar domestic pharmacies--and to inspect packages carefully.
