The
Obama Administration plan to put new generic drugs on the street faster is
another example of how Washington healthcare reformers just don’t get
it. While it is true that more generic drugs will
reduce healthcare costs, it also is true that health risks will
increase for
many individuals sensitive to even the slightest changes in their
medications.
The
Obama drug plan imposes $10 billion in fees over ten years on the
brand-name
pharmaceutical industry, to be parceled out among big drug makers to
eliminate
the so-called donut hole, or gap, in Medicare prescription drug coverage. The idea is to help patients continue taking their
original drugs instead of switching to cheaper generic versions, or
going off
their meds entirely.
The
plan’s second part prohibits pay-for-delay deals, where brand-name drug
makers
pay generic drug companies
to drop patent challenges. Proponents of this
idea say pay-for-delay
costs Americans up to $3.5 billion each year.
Generic
drugs account for more than 70 percent of all prescriptions
filled each year in
the U.S. at a savings to patients of about $8 billion a year. A different, and insidious, cost to patients
comes from the leeway given by the Food and Drug Administration in the
manufacture of generic drugs.
The
FDA requires a generic drug to be the
same as the original in dosage, safety,
strength, performance, intended use, and the way it’s taken. The rules, however, allow for a 20-percent
variation in the active
ingredient. In
other words, the good stuff may be 80 percent less than, or 20 percent
more
than, what’s in the real deal. This
broad range may work for antibiotics, but it creates nasty reactions
among
patients with heightened sensitivities to their medications.
Internet
discussion boards teem with anecdotal evidence. One person tells how his symptoms went away during the year he
took the real
drug, but returned after three months on the generic version, forcing
him to go
back to the original that cost seven times more, but with “tremendous
results.”
A
mother describes how her 11-year- old son, who takes several generic
anti-seizure drugs, received a different generic for one prescription
that made
him extremely sedated and “drool like a faucet,” which put him at risk
for
drowning in his own saliva. She calls
this another example of why the FDA should tighten its regulations and
monitoring
of generic drugs.
I
don’t have to go to the Internet to know about the dirty little secret
of
generic drugs. My wife has temporal lobe
epilepsy, in addition to being very sensitive to generics. We knew generic over-the-counter drugs may
include inactive ingredients that cause bad side effects, but we assumed
generic drugs were the same as real ones. We discovered the difference when she received a generic
anti-seizure
drug because our insurance company wouldn’t pay for the original. The doctor and pharmacist insisted there was
no difference, but a quick search of epilepsy forums turned up person
after
person with horror stories similar to hers.
Doctors
and federal agencies many times require more than a patient’s story,
which
makes you wonder why the people charged with watching out for our health
apparently
ignore a study by Giuseppe Borheini published in the 2003 issue of
Clinical
Therapeutics (http://www.ncbi.nlm.nih.gov/pubmed/12860486?dopt=Abstract). Borgheini’s team looked at available data
going back to 1975 that compared the effectiveness of brand-name psychoactive
drugs and their generic counterparts.
One
of Borgheini’s more disturbing discoveries was of a study that showed
plasma
levels of phenytoin were 31 percent lower after a switch from the
original anticonvulsant
Dilantin. He also learned that when the
FDA investigated the sudden recurrence of seizures on the generic
valproic acid
substituted for Depakote, it found a difference in how the drug gets to
where
it supposed to go.
Other
data showed statistically significant differences in favor of Valium
over the
generic diazepam in terms of the body’s absorption and distribution.
Borgheini’s
research led him to conclude the FDA’s “ essential-similarity
requirement
should be extended to include more rigorous analyses of tolerability and
efficacy in actual patients as well as in healthy subjects.”
This
would mean the FDA would have to reconsider its formula variation
requirement,
demand realistic trials of different formulations, and make sure the active
ingredient in the generic drug delivers its bullet to the same
target as the original
drug.
The
FDA will say, however, that it doesn’t have the resources to guarantee
generic drugs
do no harm. FDA Commissioner Margaret
Hamburg recently told attendees of the annual meeting of the Generic
Pharmaceutical Association her agency needs more people to review the
2,000 applications
for new generic drugs, a number that’s doubled in five years.
Her
plan is not to take more time to ensure a generic drug doesn’t harm the
patient. No, her plan is to charge generic
manufacturers
an application fee that will fund additional staff to push out more
potentially
harmful drugs as part of the Obama Administration’s effort to make
medication
affordable to everyone, regardless of the cost to health.
