[sci.med] Aspirin vs. Codeine

dyer@endor.harvard.edu (Steve Dyer) (10/19/86)

Empirin Compound used to be APC (aspirin, phenacetin and caffeine), but when the
association of chronic phenacetin use with kidney damage was noted, it was
reformulated to contain only aspirin.  Tylenol is a tradename for acetaminophen.
Both drugs named "XXX w/codeine #3" contain 325mg of either aspirin or
acetaminophen combined with 30mg of codeine.  It's not hard to imagine
patients responding better to one or the other, although they are generally
thought to be equally effective when prescribed for acute pain.

Thanks for reminding me of the need for *some* precision. I should have
made the acute/chronic distinction myself at the time. Interestingly,
the Vietnam War vet case would fall into both categories, because he
had a lot of opiate in the field hospital for the battle injuries, then
several surgeries in the next few days in his next hospital, then came
a really long period of surgeries/recoveries/more surgeries. He doesn't
talk about his drug reactions except in the first mind-boggling period,
presumably the most acute phase, but it's hardly conceivable that he
would not have developed a dependency on his analgesics as the chronic
phase followed. You're probably right, too, that people in the acute
circumstance may be undermedicated. My only first-hand experience (glad
to say) was a skiing accident (four fractures in the foot, ouch), and
I got off the codeine in about 3 days, switching to aspirin, because I
wanted my gut to work better (self likes food :-).

Be careful with those sweeping generalisations.  I am not a 200
pound man (will you settle for a muscular 74 kilograms of Elf? :-)),
but I recently had a wisdom tooth extracted.  The dentist prescribed
acetaminophen #3 in case of pain, yet I never had to use it.  In
my case, any dose would have been too high.

Strictly speaking, which I usually manage to do in sci.med, I should have
been more rigorous, although the context should have been clear.  The 
average 200lb man with moderate to severe pain after wisdom tooth extraction
would probably find 15mg of codeine hardly better than a placebo.  Obviously
if a person's not in pain, an analgesic isn't indicated.
