For more
than a decade, physician Marcia Angell served as executive editor and then
editor in chief of the New England Journal of Medicine, one of the country's
most prestigious medical journals. Under her watch, the journal published
hundreds of studies of new drugs. It also published blunt editorials harshly
critical of the pharmaceutical industry and the way drugs are tested and
approved in the United States.
Angell left the journal's
editorship in 2000, and is now a senior lecturer at Harvard Medical School. She
has written a scathing critique of the pharmaceutical industry, "The Truth
About the Drug Companies: How They Deceive Us and What to Do About It"
(Random House, 2004). In a recent conversation, she talked about why so many of
the drugs on the market are so costly, and also about her contention that many
of them are not as effective as they're promoted to be.
Question: We all know drugs
are expensive. But doesn't that reflect the high cost of researching and
developing new drugs?
Answer: No. That's what the
drug makers would like you to think. But it's simply not true. In 2002, the
biggest drug companies spent only about 14% of sales on research and development
and 31% on what most of them call marketing and administration. They
consistently make more in profits than they spend in R&D. And their profits
are immense. In 2002, the combined profits of the 10 drug companies in the
Fortune 500 were $35.9 billion. That's more than the profits for all the other
490 business put together, if you subtract losses from gains.
Q: The system may be flawed,
but hasn't it generated hundreds of new medications?
A: That's another myth the
drug makers would like you to believe. In fact, the number of truly innovative
new drugs is quite small. True, many drugs are coming to market. But most of
them aren't new at all. They are minor variations of bestselling drugs that are
already on the market.
There are dozens of examples
of these "me-too" drugs. There are now six different statins to lower
cholesterol. The first, Mevacor, which was approved in 1987, was indeed an
innovative drug. Other companies wanted to capitalize on this extremely
lucrative market and they began creating other statins. Lipitor is now the
biggest-selling drug in the world. But it's a me-too drug. There's little
scientific evidence that any of them is better than the others in comparable
doses.
Q: Doesn't the Food and Drug
Administration require new drugs to be safer and more effective than drugs
already on the market?
A: It should, but it
doesn't. Drug makers are only required to show that a new medication is more
effective than a placebo, or sugar pill. If a drug works better than a placebo
and is safe, the FDA approves it, and it can enter the market. The result is
that doctors don't know if a new drug that comes along is any better or worse
than the drugs they're already using.
A dark fear I have, in fact,
is that drugs are getting progressively worse. There's some basis for that
concern. The first drugs used to lower blood pressure were diuretics. Then new
drugs for hypertension came along and were heavily marketed, and many doctors
stopped using diuretics. In a study published in 2002, researchers compared the
old drugs to the new ones, and guess what -- the old drugs turned out to be just
as good for lowering blood pressure and even better than the new drugs for
preventing some of its complications.
Q: Why do drug makers churn
out new drugs when older ones work perfectly well?
A: Because patents run out
on older drugs and they can then be sold as generics at as little as 20% of the
price [they sold at while still under patent]. Pharmaceutical manufacturers need
a constant supply of new drugs that have patent protection so they can charge
whatever they want.
Q: Isn't it useful to have a
variety of drugs to choose from, in case a patient doesn't respond to the first?
A: That's an argument the
pharmaceutical industry makes -- that it's good to have six cholesterol-lowering
drugs, or five selective serotonin reuptake inhibitors (SSRIs), the
antidepressants that include Prozac, Zoloft and Paxil. But if that's true, then
the companies should be required to test a new me-too drug in people who failed
to respond to the first drug. And they don't do that. My guess is that if the
first drug doesn't work, the second one won't work either, since me-too drugs
are so similar. But no one can say for sure.
Q: What about competition?
Do me-too drugs help keep prices down?
A: Probably not. When did
you see a drug company advertise that its drug is cheaper than another drug? You
don't see ads that promote Lipitor as cheaper than Zocor. Or Zoloft as cheaper
than Paxil. I can't think of any other industry where price is almost never
mentioned. Drug companies compete by implying that their new drug is better. And
also by making more people think they need drugs.
Consider psychiatric drugs.
If you can define everyone who has the blues as having depression that needs to
be treated, you've created a huge market. If you define everyone who is shy as
having social anxiety disorder, that enlarges the market. There's probably not a
soul alive who hasn't felt shy. If you listen to the pharmaceutical industry,
many of the ordinary discontents of life are medical conditions that require
drugs.
You see the same thing with
erectile dysfunction. Any episode of impotence, no matter how mild, how rare,
becomes a condition, erectile dysfunction, that can be treated. It's no
coincidence that the people in those ads tend to be middle aged or even younger.
Pushing the disease is a big part of pushing the drugs. The result is that many
Americans are probably on too many medications, with all the risks of side
effects and drug interactions that implies.
Q: If new drugs aren't
necessarily better than old ones, why do doctors prescribe them?
A: Part of the answer is marketing.
New me-too drugs are heavily marketed to patients and doctors. Look at the ads
on television. Look at the endless parade of drug representatives marching
through doctors' offices. Pharmaceutical companies spend billions and billions
to make us think that new drugs are better than old ones. They have to. If you
had a drug that was important and unique, you wouldn't have to advertise it very
much. If you came out with a cure for cancer, the world would beat a path to
your door.
So you have to ask, why are
drug companies spending so much on marketing? The answer is that they
have to convince us that their me-too drugs are better than the others. And that
takes a heap of marketing, because there's usually no scientific evidence
to back up the claim.
Q: It's easier to imagine
patients being fooled -- but doctors?
A: People don't realize that
the pharmaceutical industry supports most of the continuing medical education
programs in this country. These are the programs doctors are required to attend
to update their knowledge. Drug makers fund the programs, so it's not surprising
that they promote a drug-intensive style of medicine.
In their offices, doctors
are visited by swarms of company sales representatives who bring packages of
free samples -- about $10-billion worth a year -- of the newest brand-name
drugs. The doctors get used to prescribing them, the patients get used to taking
them, and when the free samples run out, someone has to start paying for the
drug.
Whether these new drugs are
actually better than older generic drugs never crosses the doctor's mind or the
patient's mind. They confidently believe that newer is better.
Q: What about clinical
trials? Don't they provide evidence about how well drugs work?
A: Research is biased in
favor of the drugs and drug makers. The pharmaceutical industry spends a great
deal to influence people in academic medicine and professional societies. It
does a super job of making sure [that] nearly every important person they can
find in academic medicine [who] is involved in any way with drugs is hired as a
consultant, as a speaker, is placed on an advisory board -- and is paid generous
amounts of money.
Conflicts of interest are
rampant. When the New England Journal of Medicine published a study of
antidepressants, we didn't have room to print all the authors'
conflict-of-interest disclosures. We had to refer people to the website. I wrote
an editorial for the journal, titled "Is Academic Medicine for Sale?"
Someone wrote a letter to the editor that answered the question, "No. The
current owner is very happy with it." That sums up the situation nicely.
Q: What can be done to fix
the system?
A: The single most important
change that should be made -- and it could be made tomorrow -- is for Congress
to redefine what safe and effective means, to insist that the FDA require
manufacturers to test new drugs not just against placebos but against existing
drugs. After all, the relevant issue isn't whether a new drug works better than
nothing; it's whether it's better than older drugs already in use.
That's why so many clinical
trials published are of no use to doctors. Doctors don't want to know if this
new drug is better than a sugar pill. They want to know if it's better than the
drug they're already using. The FDA should require manufacturers to compare new
drugs head to head, at equivalent doses. Only drugs that are safer, more
effective, or significantly more convenient, should be approved.
We also need to make the FDA
more independent. The FDA has 18 advisory committees, and many of the members of
those committee have financial ties to the drug industry. That's wrong.
Finally, university medical
centers and medical societies and the people who run them need to stop fooling
themselves into thinking they can take huge sums of money from drug makers and
still remain objective and independent.
Q: Is there anything
patients can do?
A: Ask questions. If your
doctor prescribes a medication, ask about the evidence that shows it is
effective. Ask why your doctor is prescribing this particular drug. Ask if there
are older, less expensive drugs that might work just as well. A few questions
from patients might begin to make [doctors] think about what they're doing.
Finally, ask your doctor whether you really need a drug at all. Maybe a
lifestyle change would be better, or maybe the illness is mild and will go away
on its own.
