NSAIDs
1-2% of patients on long term NSAIDs are hospitalised for
bleeding each year
with about 1 in 6 dying.

COX 2 inhibitors or NSAID
+ PPI reduce risk of serious GI adverse event by about
the same
amount
COX 2 + PPI is the most effective way of reducing risk
The
cumulative overall risk of MI / Stroke / CV death after 1 year on
lumiracoxib vs ibuprofen or naproxen in the Target trial was just under 1%.
Bearing in mind the likely risk on placebo of ~ 0.4% the absolute risk
equates to
approximately 3 events per 1000 patients per year.
There is
insufficient evidence to prefer any NSAID or Coxib with respect to CV
risk
though some experts believe naproxen may confer a lightly lower risk.
It
is often worth trying several different preparations to find one which suits a
patient, and generally the half-life, and other pharmacological properties
are a
poor guide to how well a particular drug will suit a patient ie suck
it and see.
Aspirin appears to negate the GI benefits of
coxibs
Ibuprofen (and maybe some other NSAIDs) possibly negate the antiplatelet
effects of
aspirin!
So if the anti-platelet effect of aspirin is
important consider celebrex or
diclofenac

Patient characteristic

Advice
|
|
Patient has 2 or more risk factors for gastrointestinal toxicity but low cardiovascular risk.
|
coxib eg celebrex and a PPI
|
|
Patient has a significant risk of cardiovascular disease and 2 or more risk factors for gastrointestinal toxicity
|
Aspirin + naproxen + PPI
* aspirin appears to negate the benefit of cox 2 NSAIDs and benefits may be negated by ibuprofen |
There has been
considerable anxiety and controversy regarding the safety of
NSAIDs
following the publication of data suggesting an increased cardiovascular
toxicity. A number of expert reviews are available.
