How Do Pain Relievers Work

bamdrew says...

It is generally understood that acetaminophen/paracetemol binds and reduces oxidized, 'highly active' COX-2 enzymes... this chills out the COX-2 activity until it is oxidized again and cranks back up. So imagine in this animation acetaminophen kind-of causing that active COX binding site to close up a little for a while, and preventing it from working in that way.

Acetaminophen also doesn't appear to have a lot of anti-inflammatory action near the actual site of inflammation, but rather more globally throughout the body; folks hypothesize a lot about the reason for this, but I like the simple answer that acetaminophen itself can't reduce oxidized COX enzymes in an injured area surrounded by high levels of oxidative species.

But what about paracetamol? That's different, because you can take the allowed dosage of that and the allowed dosage of ibuprofen at the same time without interaction... but how does it work?

Paracetemol is the major painkiller here in Thailand, which annoys me because I believe that I am essentially immune to it. I took paracetemol (tylenol) often when I was in my pre and early teens for migraines. At some point, I found that it just wouldn't do anything for me anymore. Ibuprofen and Aspirin both work great, so I always use those when I have a choice -- but the default is always Paracetemol here.
