Breakthroughs that break out!
We've seen it in the news time after time, "Researchers discover
promising new breakthrough that may someday...' The keyword here
is 'someday'. Just what happens to all of those breakthroughs
that we never hear about again? Is there simply a pile of broken
promises littering the floors of research labs around the
nation, or have these new discoveries somehow slipped into our
healthcare system, and are now quietly saving lives?
The answer to both these questions appears to be- yes.
Not every drug sees itself mentioned on the cover of Time or
Newsweek. Yet there is much effort put forth by large
pharmaceutical companies to do just that. After all, 'buzz' is
good for business, investment and brand recognition.
Fortunately, reality usually wins out, harmful drugs usually
don't get to store shelves, less effective ones fall by the way
side, and the world keeps spinning.
What you may or may not know, is that some of these fallen
breakthrough drugs, while not having lived up to their initial
promise, do find a place in our medical arsenal, often with
unanticipated but welcomed results. A few drugs, like aspirin
and statins, far exceed our initial expectations.
Aspirin was first patented on March 6, 1889 by the German
company, Bayer. Its primary ingredient, salicylic acid was
originally extracted from willow plants - evidence suggests it
was even used during the lifetime of Hippocrates. Today,
mounting evidence indicates that aspirin is not only a welcome
pain reliever for headaches and muscle pains, but it also acts
as an effective anticoagulant- a blood thinning agent- that
reduces the likelihood of stroke and heart attack. Just last
month, the New England Journal of Medicine reported on a study
that showed aspirin was safer and more effective than warfarin
for preventing certain types of strokes.
Statins, cholesterol lowering drugs marketed under brands like
Lipitor, Zocor and Crestor among others, have shown to be
another group of wonder drugs. In addition to lowering
cholesterol, there is growing evidence that statins also help
protect against Alzheimer's disease. One new study indicates
that statins help in reducing fats and proteins in the blood
that have been linked to atherosclerosis. A clinical study in
Great Britain showed that the use of statins may be beneficial
in reducing the symptoms of rheumatoid arthritis.
While these are the most well know examples of breakthrough
drugs breaking out, others include: Methotrexate, sold under the
brand Rheumatrex, was original intended for cancers, but is now
widely used to treat rheumatoid arthritis. Don't forget
glucosamine (a nutritional supplement) that seems to reduce
osteoarthritis pain. As for bretylium, new research indicates
that this drug once used to treat ventricular fibrillation shows
promise for heart-attack patients.
Diuretics or 'water pills,' are shown in recent studies to lower
blood pressure more effectively that newer drugs - including
calcium channel blockers and ACE inhibitors.
One pioneering effort under way at the University of Washington,
involves a compound called artemisinin. Derived from the herb
Artemsisia annua, and used by the Chinese to effectively fight
malaria since the 1970s, artemisinin is now the focus of
exciting new cancer research being conducted by Henry Lai and
Narendra Singh, both UW bioengineers. These scientists have
combined artemisinin with transferrin, a blood component that
transfers iron to the cells. According to Dr Lai, "Our research
results indicated that the new artemisinin compound is 34,000
times more potent in killing the cancer cells as opposed to
their normal cousins."
The list goes on. Arsenic trioxide, approved for treating a rare
form of leukemia, may also work in treating an incurable form of
brain cancer called glioblastoma. Suramin, a drug once used to
treat parasitic infections is being studied as a treatment for
cancer.
The search for new cures is often fraught with disappointment
and suspicion, but the search goes on none-the-less. While we
leave the science to the chemists, doctors and physicists, we as
health consumers, have a responsibility to ourselves and
families to be as informed as we possibly can about our own
health and the treatments and medicines that are available right
now.
