Why does everyone seem
to hate the pharmaceutical industry, especially since it is
making products that save and enrich lives?
John Le Carré, the bestselling
British writer famous for his Cold War spy novels, was not
going out on a limb when he cast pharmaceutical companies
as the new global villains in his 2000 novel, The Constant
Gardner. The pharmaceutical industry is now one of the
top targets of politicians and much of the public for ire,
wrath, and (possibly) regulation. The most frequent complaint
is that prescription drugs cost too much, that their costs
are spiralling out of control.1
Many critics have made the
mistake of confusing more spending with higher prices. Prices
are not going up-consumers are buying more. In the United
States, spending on prescription drugs is rising rapidly because
people are buying more pills,2
as doctors and patients take advantage of the more and better
drugs that are now available.
During the 1990s, the pharmaceutical
industry developed nearly 400 new drugs, many of which act
as substitutes for older, more expensive medical treatments.
When other industries develop new products that people want-personal
computers, say, or cell phones-we typically laud them for
their innovation and willingly spend our money.
So why are pharmaceutical companies
the targets of so much criticism, especially since they are
making products that save and enrich lives? The answer includes
political opportunism, large doses of ignorance regarding
the drug industry's economics, and an entitlement mindset
among many consumers. Those are potent sentiments that, in
today's policy climate, are particularly troubling. If enacted,
the most common proposed solutions to the prescription drug
'problem' would actually undermine an industry that has greatly
enriched quality of life.
Cost analysis
In absolute terms, consumers
in the United States are spending more on prescription drugs.
But spending totals are not the end of the analysis.3
A more important question is whether consumers are getting
value for money. According to Columbia University economist
Frank Lichtenberg, the answer is a resounding yes.
Between 1960 and 1997, life
expectancy at birth for Americans rose from 69.7 years to
76.5 years. 'Increased drug approvals and health expenditure
per person jointly explain just about 100% of the observed
long-run longevity increase,' writes Lichtenberg in a working
paper done last year for the National Bureau of Economic Research.
Lichtenberg found that for
an expenditure of $11,000* on general medical care, there
is a gain of one life-year on average. (A life-year in this
context is simply an extra year of life that a patient gains
by being treated.) However, spending just $1,345 on pharmaceutical
research and development gets the same result. Economists
have calculated that, on average, people value an extra year
of life at about $150,000. (That figure is based on people's
willingness to engage in risky jobs.) Assuming an average
value of $150,000 per life-year, the benefits from medical
care expenditures outweigh the costs by a factor of more than
13; the benefits of drug R&D are more than 100 times greater
than its costs.
As important, drugs can also reduce health care costs. In
'Do (More and Better) Drugs Keep People Out of the Hospital?'-a
1996 study published in the American Economic Review-Lichtenberg
found that 'a $1 increase in pharmaceutical expenditure is
associated with a $3.65 reduction in hospital-care expenditure.'
The story of stomach-acid-blocking
drugs such as Tagamet and Zantac illustrates how drugs save
money by keeping patients out of hospital. In 1977, the year
in which such drugs were introduced, surgeons performed some
97,000 operations for peptic ulcers. In 1993, despite population
growth, that number had shrunk to 19,000. The shift from surgery
to highly effective pills-a change that has made life better
for tens of thousands of people with stomach problems-is the
sort of quiet development that escapes much attention. The
Boston Consulting Group's health care practice reported that
it saves patients and insurers at least $224 million in annual
medical costs.
Other examples abound. In 1991,
for instance, the benefits that drugs offered became painfully
apparent when New Hampshire, in a cost-saving measure, adopted
spending caps on the number of reimbursable medications that
Medicaid patients could receive. The result was that nursing
home admissions doubled among chronically ill elderly patients
and raised government costs for institutional care by $311,000,
which was 20 times more than was 'saved' by imposing spending
caps on drugs. As John Calfee, a drug policy analyst at the
American Enterprise Institute, has noted, drugs that break
apart blood clots cut hospitalisation and rehabilitation costs
for stroke victims by about four times the cost of the drug.
In his recent monograph Prices, Markets and the Pharmaceutical
Revolution, Calfee also reports that schizophrenia drugs costing
$4,500 per year save more than $70,000 in annual institutional
treatment costs.
A yearlong study of 1,100 patients
done by Humana Hospitals found that using drugs to treat congestive
heart failure increased pharmacy costs 60%, but cut hospital
costs by 78%, for an overall savings of $9.3 million. Better
still, the death rate dropped from an expected 25% to 10%.
In Virginia, an asthma study found that new asthma drugs cut
emergency room visits by 42%. And a study by the consulting
firm William M. Mercer concluded that every $1 spent on non-sedating
antihistamines yielded a $3.07 return to employers, due to
increased productivity and reduced accident costs.
'The ability of pharmaceuticals to reduce the total expenditures
for health care, as well as business costs, is important but
secondary,' concludes Calfee. Modern drug therapy means 'patients
and consumers . . . are gaining . . . better health, longer
life, reduced pain and discomfort, and other blessings.'
No
other industry has nearly as high R&D expenses,
[for] drug discovery and development is a notoriously risky
business.
'Obscene profits'
Some critics of the industry
grant that drugs dramatically cut some medical costs. But,
they say, the drug makers are reaping huge-obscene, really-profits.
In fact, drug company profits as conventionally calculated
do run to as much as 20%, while 5% profit margins are typical
of many other American industries. That 20% figure, however,
is deceptive, since the standard accounting procedures used
to calculate drug company profits write off R&D costs
as 'current expenses'. No other industry has nearly as high
R&D expenses, so when other industries write off their
R&D it does not have as much effect on their rate of return
calculations. If pharmaceutical R&D were depreciated over
time, then annual profits for the industry drop to around
9%.
That is still almost double
the average rate of return. What explains it? Drug discovery
and development is a notoriously risky business. 'Some 5,000
to 10,000 molecules are screened and only one will make it
to being a drug,' explains Kees Been, vice president for business
and marketing at Biogen Inc., a leading biotech pharmaceutical
company based in Cambridge, Massachusetts. 'From discovery
to launch takes 12 to 16 years. Only 30% of all products ever
invented returned more than what was invested in them,' adds
Been. That means that 70% of the drugs currently available
for treating and curing people are in fact economic losers
for the companies that developed them.
A 1999 study by Duke University
economists Henry Grabowski and John Vernon for the Tufts University
Center for the Study of Drug Development analysed the sales
of a category of drugs introduced between 1988 and 1992. The
study found that the top 10% of new drugs accounted for more
than half the total sales revenues of drugs. 'The returns
to R&D projects in pharmaceuticals have similar properties
to that of venture capital investments,' conclude Grabowski
and Vernon. In other words, drug companies, like venture capital
firms, throw money at a lot of different high-risk projects
knowing that virtually none will pan out, but that a few may
score real jackpots.
These jackpots cover the losses
on the other projects and, perhaps more important, pay for
future bets. In this way, revenues from such blockbuster drugs
as Prozac for depression, Celebrex for arthritis pain, Viagra
for erectile dysfunction, and Lipitor for controlling cholesterol
levels do more than cover the costs of the majority of drugs
that do not make a profit; they also fuel further research.
Investment in R&D for any
given drug is not trivial. Typically, it costs between $300
million and $500 million to bring a single drug from being
a gleam in a lab jockey's eye to delivery to the marketplace.
Yet one argument that critics often make is that drug companies
sell their pills for dozens, if not hundreds, of times more
than it costs to make them. The liberal policy magazine The
American Prospect made just this case in its 11 September
2000 issue in an article titled, 'The Price Isn't Right.'
The piece cites an analysis that claims Bristol-Myers Squibb
can manufacture a patient's 18-month supply of the popular
cancer drug Taxol for just $500, but charges over 20 times
more than the manufacturing costs.
This kind of 'analysis' is willfully stupid. For many products
whose value is essentially embodied in intellectual property-drug
makers get a 20-year patent on new drugs-copies can be manufactured
very cheaply once the product has been developed. Hence, it
may cost hundreds of millions of dollars to create the first
copy of a computer program, but the second copy is little
more than the cost of the CD onto which it can be downloaded.
The same holds true for most pharmaceuticals. Manufacturing
that first pill takes millions in conducting research and
clinical trials, in processing regulatory filings and building
a factory, in establishing distribution channels and generating
advertising. The second pill may indeed take only pennies
to make physically, but virtually all the money to create
it has already been spent by the time that second pill goes
into a pharmacist's bin.
'A pill is very small, so people
have the intuition that it shouldn't have a high price,' says
Alison Keith, who recently stepped down as head of economic
and science policy analysis at pharmaceutical giant Pfizer.
'But a better way to think about our medications is that they
are small tablets wrapped in huge envelopes of information.'
Double billing?
A related charge regarding
pharmaceutical costs is the idea that patients are actually
paying for drugs twice-the first time as taxpayers through
government-funded scientific research and again as patients,
when they go to their local drugstore to pick up their prescriptions.
'Research funded by the public sector-not the private sector-is
chiefly responsible for a majority of the medically significant
advances that have led to new treatments of disease,' argues
The American Prospect.
Is that true? The annual budget
of the National Institutes of Health (NIH), the major government
grant-giving institution for medical research, was $17.8 billion
in 2000 and is expected to rise to $20.5 billion this year.
Meanwhile, the pharmaceutical companies' R&D budgets totalled
$26.4 billion last year-almost 50% more than the 2000 NIH
budget. (Industry R&D expenditures equal more than 20%
of what pharmaceutical companies make in total sales, making
the industry the most research-intensive business in the world.)
What roles do government and private-sector research actually
play in the drug discovery and development process?
'Government-supported research
gets you to the 20-yard line,' explains Duke's Grabowski.
'Biotech companies get you to the 50-yard line and [the big
pharmaceutical companies] take you the rest of the way to
the goal line. By and large, government labs don't do any
drug development. The real originator of 90% of prescription
drugs is private industry. It has never been demonstrated
that government labs can take the initiative all the way'
to drugstore shelves.
George Whitesides, a distinguished
professor of biochemistry at Harvard University, similarly
appreciates the role of often government-funded research labs
at universities in the early stages of drug development. But
he stresses that 'pure' research rarely translates into usable
products. 'The US is the only country in the world that has
a system for transmitting science efficiently into new technologies,'
he argues. That system includes research universities that
produce a lot of basic science and get a lot of government
money. In turn, startup companies take that lab science and
develop it further. 'Startups take 50% of the risk out of
a product by taking it up to clinical trials,' explains Whitesides.
'Industry has an acute sense of what the problems are that
need addressing.' Without private industry to mine the insights
of university researchers, taxpayers would have paid for a
lot of topnotch scientific papers, but few if any medicines.
Frank Lichtenberg, the Columbia
economist, has a slightly different take on the question of
whether patients are paying twice for drugs. He cites the
example of Xalatan, a glaucoma drug developed by Pharmacia
& Upjohn. Last April, The New York Times ran a news story
suggesting that although some of the original research on
Xalatan was backed by a $4 million NIH grant in 1982, the
'taxpayers have reaped no financial reward on their investment.'
Not so fast, says Lichtenberg. In 1999, Xalatan represented
7% of sales for Pharmacia & Upjohn, so Lichtenberg reasonably
assumes that 7% of the company's $344 million in corporate
income tax payments that year can be attributed to Xalatan.
Thus Pharmacia & Upjohn paid about $24 million in income
taxes on its 1999 sales of Xalatan. Just counting that one
year of increased taxes as if it were the only return ever
for a 17-year-old investment, Lichtenberg calculates that
this yields a very respectable 11% return on the taxpayers'
money. In fact, future sales are very likely to be higher,
'so the return on the taxpayers' investment is likely to be
considerably greater.'
Placebo effect
'Big drug companies are putting
more money into advertising and promotion than they are into
research and development,' said Al Gore on the campaign trail
last year, neatly summarising another popular complaint against
the pharmaceutical industry. This widespread assertion, however,
is just plain wrong. In 1999, for instance, the pharmaceutical
industry spent $13.9 billion on advertising and promotion.
(Half the promotion costs, incidentally, were for drug samples
that doctors give to patients for free.) R&D expenditures
for 1999 were more than $24 billion.
There are, to be sure, more
drug ads around these days. In 1997, the Food and Drug Administration,
concerned about a couple of First Amendment lawsuits against
its regulations, relaxed its restrictions on advertising prescription
drugs. Since then, there has been an explosion of direct-to-consumer
television and print ads for prescription drugs. In 1999,
pharmaceutical companies spent $1.8 billion appealing directly
to consumers. Industry critics charge that advertising directly
to consumers causes patients to demand drugs they do not need.
As Gore put it, drug makers were nefariously 'spending hundreds
of millions of dollars on television and on magazine advertising
to persuade people to buy newer and more expensive medications
when less expensive versions work just as well.'
Such charges raise several
issues. First, do less-expensive medicines work just as well
as those 'newer and more expensive ones'? In a study of the
benefits and costs of newer drugs, Lichtenberg shows that
older drugs are, in general, not as good as newer drugs. Using
data from the 1996 Medical Expenditure Panel Survey, an in-depth
national survey of the health care expenditures of more than
22,000 people, Lichtenberg developed an econometric model
to compare the costs and benefits of using older and newer
drugs to treat similar medical conditions. He concluded that
'the replacement of older by newer drugs results in reductions
in mortality, morbidity, and total medical expenditure.' Lichtenberg
also found that 'denying people access to branded drugs [as
opposed to cheaper generic drugs] would increase total treatment
costs, not reduce them, and would lead to worse outcomes'.
Newer is better.
What about the claim that advertising
simply tricks consumers into demanding more expensive drugs?
Obviously, advertising can generate interest in a product-that,
after all, is the whole point. But the idea that advertising
can simply create a demand for a worthless product is no less
convincing when it comes to medical care than it is for other
goods and services. If anything, it is less so in this case,
since the advertiser needs to convince two buyers-the patient
and her doctor-to make a sale.
More to the point, such criticisms
ignore basic realities of the health care market. 'There are
substantial societal benefits to health from consumer advertising,'
says Alison Keith from Pfizer. 'Patients have a lot of information
about themselves that otherwise would not go into the medical
system.' A survey in 1999 by Prevention magazine estimated
that direct-to-consumer advertising encouraged nearly 25 million
patients to talk with their doctors about illnesses or medical
conditions that they had never discussed before. As important,
by providing inform-ation outside of the traditional doctor-patient
relationship, direct-to-consumer advertising can also give
patients some protection against incompetent or indifferent
physicians who have failed to keep up with new developments.
'The industry . . . also downplays
the fact that many "new" drugs aren't medical breakthroughs,'
complains The American Prospect. 'About half of industry research
is aimed at developing me-too drugs,' that treat problems
already addressed by existing medications, it adds. The implication
is that companies are simply trying to take market share away
from each other without providing any 'real' benefits to patients.
Such a scenario ignores the
simple fact that companies are likely to be researching similar
drugs to begin with and that one firm has to be first to market.
But so-called me-too drugs actually benefit patients, not
simply by offering different treatments for similar conditions-Tagamet
and Zantac, for instance, have different active ingredients-but
by driving down prices in a given treatment category.
'The period of one-brand dominance for an innovating drug
within a breakthrough therapeutic category has unmistakably
shortened,' writes AEI's Calfee. This faster competition leads
to price cuts among competing medicines. Hence, when new anti-depressant
medications were introduced in the mid-1990s, they cost only
53% as much as Prozac did when it first hit shelves in 1988
and had the field more or less to itself. Similarly, new cholesterol-lowering
drugs that came to market in the mid-1990s cost 60% less than
pioneering effort Mevacor did when it first showed up in 1987.
So-called
me-too drugs actually benefit patients, not simply by offering
different treatments
for
similar conditions, but by driving down prices in a given
treatment category.
First, do no harm
The Hippocratic Oath famously
insists that doctors do nothing to worsen a patient's condition:
First, do no harm. Unfortunately, when it comes to most policy
recommendations regarding prescription drugs, the potential
for harm, usually in the form of price controls and universal,
mandatory coverage, lurks everywhere.
Central to virtually all 'reform'
agendas is reining in drug company profits. Will that contain
health care costs? 'Suppose we seize all pharmaceutical profit,'
suggested Sidney Taurel, CEO of Eli Lilly
& Co., in a speech last October. 'Drugs are just 8% of
total health care. To simplify the arithmetic,
let's stretch and say [profits are] 20% of sales. Some 20%
of 8% equals just 1.6% of total health care costs. Does that
sound like a solution to you?' Despite its political appeal,
it's not much of one. In fact, that sort of thing would almost
certainly retard the development of new drugs by destroying
the incentive for research. (It's not called the profit motive
for nothing.)
Given their relatively small
cost as a percentage of health care dollars and overall household
consumption, why have drugs raised the ire of politicians
and populists so forcefully? The short answer is third-party
payments. 'Most of the drugs are not being paid for by users.
Third parties are paying but not getting the benefits, so
they are very concerned about costs,' explains AEI's Calfee.
As doctors prescribe more drugs to cure and ameliorate the
ills that afflict their patients, this means that health insurance
and managed-care providers are spending more on drugs. Insurers,
in turn, pass along the additional spending to their customers,
companies who provide job-based medical coverage, whose bottom
lines are squeezed by the additional spending.
In many cases, spending on
drugs does lower health care costs, but often enough the new
drugs do cost more than earlier, less effective therapies,
so third-party payers are shelling out more money while patients
are getting greater benefits. From a strictly actuarial point
of view, it is cheaper for patients to drop dead of heart
attacks than for the government or insurers to pay for years
of cholesterol-lowering life-extending drugs. Employers who
do not want to pay the rising costs for employee health insurance,
and politically potent seniors who have been schooled by Medicare
to think that all health care is a right, complain to legislators
that drug costs are out of control. Such complaints focus
on increased spending on drugs, while ignoring the costs saved
through pharmaceutical treatments and the suffering and disability
that afflicted patients before pharmaceutical companies developed
the new drugs.
The policy initiatives that
respond to such complaints are fraught with problems. Those
that simply award consumers more money specifically earmarked
for drugs amount to little more than corporate welfare, by
giving pharmaceutical companies a new revenue stream. More
typically, though, policies that address prescription drugs
end in some sort of price control scheme that, by undercutting
the possible return to investment in the pharmaceutical industry,
will over time harm patients by reducing the supply of new
drugs. During the debate over the Clinton health plan, notes
AEI's Calfee, just the threat of price controls spooked pharmaceutical
R&D. 'Growth in research spending dropped off dramatically
from 10% annually to about 2% per year,' according to Calfee.
It is because of its relatively
unregulated market that the US provides the rest of the world
with new drugs. Over the past two decades, companies in the
US have produced nearly 50% of the world's leading pharmaceuticals.
Today, US drug companies make all ten of the world's best-selling
drugs. Due to other countries' price controls, pharmaceutical
research and development has increasingly been centred in
the United States.
Conclusion
We are entering a golden age
of pharmaceutical research. With the completion of the Human
Genome Project, 'all pharmaceutical targets until the end
of time are now known,' said Biogen's Kees Been, at a presentation
in December at the Massachusetts Institute of Technology.
At the same meeting, Sean Lance, CEO of Chiron, a biopharmaceutical
company located near San Francisco, predicted, 'We are going
to win over HIV, malaria, and tuberculosis because of biotech.'
Such certitude-bordering on
arrogance-would be irredeemably smug, if not for the pharmaceutical
industry's track record in raising the quality of life. 'In
the 1950s and 1960s, doctors performed millions of tonsillectomies
and put grommets in the ears of children to prevent earaches.
Now we know that they don't work,' said Lance. 'In ten years'
time, we're going to look back and laugh at what we're thinking
are complicated issues and technologies today.'
If we want the pharmaceutical
and biotech companies to find and market new life-saving,
life-enhancing drugs to cure and treat heart disease, cancer,
dementia, diabetes, AIDS, and other illnesses, then it would
be wise to let the sort of relatively unfettered market competition
that has worked well in the past continue into the future.
In a recent article in Science,
Jurgen Drews, chairman of International Biomedicine Management
Partners and former head of global research at Hoffman-La
Roche, concludes that 'free markets will be capable of generating
the technical and institutional instruments that are needed
to apply scientific advances to the solution of societal problems.'
True enough. But only if we let them.
Endnotes
1 Americans are spending more on prescription drugs than
they used to. In 1997, total spending on drugs increased by
14.2% from the previous year; in 1998, it went up 15.7%; and
in 1999, it rose again by 18.8%. During that same time span,
the overall inflation rate never rose above 3% p.a.
2 Between 1993 and 1999, overall inflation in the US
rose 19% while drug prices increased 18.1%. In some years
inflation outstripped drug price increases, while in others
drug prices rose faster than inflation. For example, in 1996
inflation was 3.3% and drug prices increased only 1.6%; in
1998, inflation rose 1.6% and drug prices went up 3.2%.
3 Average expenditures per household were $301 in 1993
and $370 in 1999.
