That's a tricky question, Veebo. I googled around on the internet, but I really didn't find anything helpful. Here's what I'm thinking...
The narcotic effect of the tramadol calms your body down in addition to helping with pain... Maybe it calms your digestive tract, which in turn calms your fever? In that sense, the acetominaphen in it is sort of pointless. I know that sometimes even taking a sleeping pill helps my guts because it puts THEM to sleep as well... maybe it's the same sort of deal?
Another possibility is that the difference in efficacy is related to a difference in "binders" or "fillers" in the different pills. Maybe the tramadol has a special binder that helps it be absorbed in a certain way? That might help the tylenol be absorbed too... You might ask your pharmacist, if you have a good one.
I'm curious now, so if you piece this one together let me know!
