Have you ever taken the drug Vioxx or celebrex?
In September 2004 the drug manufacturer Merck decided
to recall the product after long term data suggested
a serious potential side effect.
This drug and others like it such as as 'Celebrex',
'Bextra' and 'Arcoxia' are part of a family of drugs
known as "COX2 drugs" or "COX2 inhibitors"
They have been developed with, ironically, patient safety
in mind.They are typically used in treatment of arthritis,
though high dose vioxx was promoted for short term relief
of acute muscular/skeletal pains.They were anti-inflammatory
drugs.
The serious side effects were in connection with the heart
suggesting risk of heart disease or heart attack.In medical
circles it was referred to as "..adverse cardiovascular effects."
There are other drugs used to treat inflammation that have been
around for many years.YOu may have heard of products such as
Advil or Nurofen which contain the ingredient Ibuprofen.Other
older anti-inflammatory drugs include such brands as Voltarol
or Naprosyn.
What's the difference between these older drugs and the recent
treatments know as "COX2 drugs"?
The newer drugs such as Arcoxia,Celebrex and Vioxx were designed
to be much more specific in their mode action than old drugs
like Ibuprofen.The idea was to limit the associated problems
in long term treatment.
When we get older we all seem to get more sensitive to side
effects of drugs.Often this is complicated even more by the
fact that we may suffer from more than one problem or disease
at the same time.
At this point we take more medication in the last five to ten
years of our lives than in all the other years put together!
Is it any wonder we might feel under the weather, a little off
colour even?
You could have asthma and high blood pressure.
Anxiety and lack of sleep every night.
Panic attacks and depression.
If you take an anti-inflammatory drug for a given length of
time, your doctor/physician will no doubt tell you about
one major problem.
Ulceration of the stomach or intestines.....
It was hoped that the newer COX2 drugs would not cause this
problem at all.Therefore it would avoid the risk of someone
suffering internal bleeding which could become fatal.
The older you become the greater the risk of this occuring.
It could be a slow blood loss or a sudden episode of an ulcer
bleeding more profusely.
So when people got the signs of ulcers, they got treatment
for an ulcer. Some would stop taking medication and others
would take a maintenance dose to prevent ulcers coming back
while continuing to take the old ibuprofen drugs for their
arthritis.
It was hoped drugs like vioxx would stop this, but ulceration
still remains a possibility. Doctors routinely consider offering
anti ulcer drugs to reduce the probability of this happening.
So what is the all the recent fuss about ? Where did it all
suddenly seem to unravel after all that hope and expectation ?
A new long term study seemed to indicate some degree of risk
to the heart some 18 months or so after starting treatment.
So if you took vioxx for a week or a couple of months, this
potential problem did not appear.It has only been spotted
after taking the medication for a longer period such as
18 months.
What can you do? Are there ways to reduce risks?
This is something you need advice on as only your doctor will
have your medical history.There is much to consider and such
a problem can in some circumstances be minimised.
Of course if you smoke you increase the risk of stomach
or intestinal ulceration if you also take anti-inflammatory
drugs such as Ibuprofen.Why not quit instead?
If you take other medication for depression or anxiety then
these drugs can increase the risk of bleeding with any
anti-inflammatory drug being taken at the same time.
