Half of Internet Viagra Could Be Fake - Study
Tue Sep 28, 2004 09:09 AM ET

LONDON (Reuters) - As many as half of the Viagra anti-impotence pills sold on the Internet could be counterfeit, British scientists said on Tuesday.

They analyzed samples of Viagra sold on the Web and found that some of the little blue pills contained different components or less of the active ingredient than the top-selling drug made by pharmaceutical giant Pfizer Inc.

"On our initial estimate, around half of those Viagra samples could be counterfeit," Dr Nic Wilson, of the University of London, told the British Pharmaceutical Conference.

Viagra, which works by allowing more blood-flow to the penis during sexual arousal, is a lifestyle drug along with hair-loss and weight treatments. All are widely available on the Internet and major targets for counterfeiters.

With impotence, or erectile dysfunction (ED), affecting about 152 million men worldwide, there is a huge market for the treatment. It is estimated that half of all men over 40 experience some degree of ED, which increases with age. About 95 percent of cases can be successfully treated.

The bogus drugs were branded and labeled Viagra and came in identical packaging to the real thing.

"What we are talking about is somebody selling something as Viagra which is clearly not made by Pfizer," Wilson's colleague Professor Tony Moffat said in a telephone interview.

The scientists are not sure whether wrong components in the bogus pills are harmful, but at the very least it is highly probable the fakes will not work.

If the counterfeiters get the dose wrong and the bogus pills contain too much of the active ingredient, sildenafil, it could be dangerous.

"Part of the side reaction of the sildenafil is increased heart pressure, so people could get heart attacks," Moffat added.

"If you go to a site that looks a bit wonky, they are selling it cheap and you've got no address or idea where they are based, you are chancing it."

Wilson and Moffat used a technique called near infrared (NIR) microscopy which provides a more detailed picture of what is in a tablet and its active ingredients to separate the fakes from the real thing.

The researchers tested the technique on known counterfeit Viagra before using it on pills they bought on the Internet. Pills arrived from a variety of countries including Thailand, India and Malta.

Eventually they believe the technology will be able to track the counterfeit products across the world.

Some Viagra Bought Online Is Not The Real Thing

November 23, 2004
NBC 10.Com


Every second, nine more tablets of Viagra are dispensed around the world. But a recent study estimated as many as half of the Viagra sold on the Internet could be fake.

Millions of men say Viagra makes them feel like the love machine they want to be but that could all come to a screeching halt if they buy their thrill in the little blue pill off the Internet.

"We've found counterfeit Viagra that has had almost 400 times the maximum active ingredient. That's a dangerous product," said John Therriault, vice president of global security for Pfizer, the maker of Viagra.

Therriault used to chase crooks for the Federal Bureau of Investigation. Now he cracks counterfeit prescription drug rings for Pfizer.

"We've found people manufacturing counterfeit products in grubby garages and warehouses in Columbia and in out of the way places in China," Therriault said.

Just imagine the quality control available in a makeshift garage or in a bedroom in Thailand. Some studies show when you order off the Internet there is a 50 percent chance your Viagra is coming from these unsanitary places.

If you think you would be able to tell the difference between the real stuff and a fake when you get your Viagra in the mail, you may be fooling yourself.

"It's like the wild, wild west. You just don't know what you're going to get," said Michael Cohen, of the Institute of Safe Medication Practices.

The NBC 10 Investigators decided to order from five different Web sites to find out what they would get. Pfizer helped with the testing.

Days after ordering, the first delivery arrived in a prescription bottle from a pharmacy in New York. It looks like the real thing and Pfizer confirmed that it was.

The second shipment came in a neat little box and, again, it was real Viagra.

The third shipment was also Viagra, but it was a free sample from a doctor's office. Cohen said it is illegal in the United States for physicians or pharmacists to sell free samples.

The fourth package arrived from India. There was no little blue pill, instead it was a pill called Caverta. The Food and Drug Administration calls Cavarta a foreign generic and it has not been approved in the United States.

The final package contained white pills from Great Britain. The FDA said the pills mimic Viagra and are illegal in the United States.

"You have no idea what the ingredients are. You don't know if it is too much or too little in that pill and people get hurt. It could cause cardiac side effects, including making your heart stop," Cohen said.

If you do have a problem, there is nowhere to complain. Many of the Web sites are overseas and can disappear or move overnight.

How do you make sure you are getting the legitimate prescription drug you need? If you are you are buying drugs on the Web, most experts say you should deal with a site that has the seal of the National Association Of Boards Of Pharmacy.
