Know anyone who uses Statin drugs? What are the other issues that happen with the statins?

o As the
world's most-prescribed class of medications, statins indisputably qualify for
the commercial distinction of "blockbuster." About 24 million
Americans take the drugs — marketed under such commercial names as Pravachol,
Mevacor, Lipitor, Zocor and Crestor — largely to stave off heart attacks and strokes.
FOR THE RECORD:
An article in Monday's Health section on the effectiveness of statins said that
the drugs appeared on the American pharmaceutical landscape in the late 1990s.
The first statin, lovastatin, was approved by the Food and Drug Administration
for marketing in 1987 and appeared on the U.S. market the same year.
At the
zenith of their profitability, these medications raked in $26.2 billion a year
for their manufacturers. The introduction in recent years of cheaper generic
versions may have begun to cut into sales revenues for the brand-name drugs
that came first to the market, but better prices have only fueled the
medications' use: In 2009, U.S. patients filled 201.4 million prescriptions for
statins, according to IMS Health, which tracks prescription drug trends. That's
nearly double the number of prescriptions written for statins in 2001, four
years after they arrived on the American pharmaceutical landscape.But in
recent months the drugs' touted medical reputation has come under tough
scrutiny.Statins
were initially approved by the Food and Drug Administration for the prevention
of repeat heart attacks and strokes in patients with high cholesterol who had
already had a heart attack. And used for that purpose — called "secondary
prevention" — the drugs are powerful and effective medications, driving
down patients' risk of another heart attack or stroke by lowering their levels
of LDL (or "bad") cholesterol.Then
physicians came to believe statins could also reduce the risk of a first heart
attack in people who have high LDL cholesterol but are nonetheless healthy.
This use of statins — called "primary prevention" — has driven the
growth in the market for statins over the last decade.Today, a
majority of people who use statins are doing so for primary prevention of heart
attacks and strokes. It is this use of statins that has come under recent
attack."There's
a conspiracy of false hope," says Harvard Medical School's Dr. John
Abramson, who has cowritten several critiques of statins' rise, including one
published in June in the Archives of Internal Medicine. "The public wants
an easy way to prevent heart disease, doctors want to reduce their patients'
risk of heart disease and drug companies want to maximize the number of people
taking their pills to boost their sales and profits."The stakes of manyHeart
patients and their physicians are not the only ones to pin their hopes on
statins. The drug companies that brought statins to the market have explored
the medications' benefits in prevention or treatment of such conditions as
Alzheimer's disease, rheumatoid arthritis, prostate and breast cancer, kidney
disease, macular degeneration and diabetic neuropathy. Although clear proof
that statins could forestall or treat any of these diseases might bring in
millions of new, paying customers, results have largely been mixed,
inconclusive or disappointing.In an
ideal world, debate over the clinical virtues or vices of a drug would be long
settled by the time the medication saw a meteoric rise in use. But in a
healthcare system that relies on commercial incentives to spur drug
development, prescription medications are a product like any other.The FDA
assesses drugs' safety and effectiveness for specific use; but its judgments
are based on preliminary data, most of it generated by a drug company seeking
approval for its product. Once the agency approves a drug for marketing, the
company that makes it will move quickly and aggressively to expand the universe
of patients taking its product.Sometimes,
by the time the deliberate pace of medical research and debate suggests that a
drug is not all it's been cracked up to be, it's already become a bestseller.
Statins, say some who study the relationship between medicine and the drug
industry, seem to fit that pattern.
