Is acetomenophen (Tylenol) an NSAID?

Tylenol is bad especially if on gear. Very hard on liver
I copied this from the tylenol web site
Alcohol warning: If you consume 3 or more alcoholic drinks every day, ask your doctor whether you should take acetaminophen or other pain relievers/fever reducers. Acetaminophen may cause liver damage

non-steroidal anti-inflammatory
<pharmacology> A large group of anti-inflammatory agents that work by inhibiting the production of prostaglandins. They exert anti-inflammatory, analgesic and antipyretic actions.
Examples include: ibuprofen, ketoprofen, piroxicam, naproxen, sulindac, aspirin, choline subsalicylate, diflunisal, fenoprofen, indomethacin, meclofenamate, salsalate, tolmetin and magnesium salicylate.
A contrast is made with steroidal compounds (such as hydrocortisone or prednisone) exerting anti-inflammatory activity.
Acetaminophen (tylenol) is not a NSAID.

We examined the effect of two commonly consumed over-the-counter analgesics, ibuprofen and acetaminophen, on muscle protein synthesis and soreness after high-intensity eccentric resistance exercise. Twenty-four males (25 +/- 3 yr, 180 +/- 6 cm, 81 +/- 6 kg, and 17 +/- 8% body fat) were assigned to one of three groups that received either the maximal over-the-counter dose of ibuprofen (IBU; 1,200 mg/day), acetaminophen (ACET; 4,000 mg/day), or a placebo (PLA) after 10-14 sets of 10 eccentric repetitions at 120% of concentric one-repetition maximum with the knee extensors. Postexercise (24 h) skeletal muscle fractional synthesis rate (FSR) was increased 76 +/- 19% (P < 0.05) in PLA (0.058 +/- 0.012%/h) and was unchanged (P > 0.05) in IBU (35 +/- 21%; 0.021 +/- 0.014%/h) and ACET (22 +/- 23%; 0.010 +/- 0.019%/h). Neither drug had any influence on whole body protein breakdown, as measured by rate of phenylalanine appearance, on serum creatine kinase, or on rating of perceived muscle soreness compared with PLA. These results suggest that over-the-counter doses of both ibuprofen and acetaminophen suppress the protein synthesis response in skeletal muscle after eccentric resistance exercise. Thus these two analgesics may work through a common mechanism to influence protein metabolism in skeletal muscle.

The guys that did this study and another one as well started out with the assumtion that is in all the medical texts, namely that Tylenol is not an NSAID because it only works on the central nervous system to blunt the pain sensation. After seeing the results of their experiment, they concluded that in fact Tylenol does act peripherally, since it is inhibiting prostaglandin synthesis in muscle, just like other NSAIDS. They concluded that in fact Tylenol is an NSAID.

Well by definition it can't be an NSAID because it is widely known that it does not reduce swelling right? I mean it might have similar actions to an NSAID on muscle synthesis but it's not going to reduce the swelling in a twisted ankle they way ibuprofen is.
Correct me if I am wrong.

It actually does reduce swelling. Here is one of several Medline abstracts. Paracetamol is just another name for Tylenol.

The choice of drugs to reduce pain and excessive inflammatory reactions after surgery or accidental trauma is reviewed and discussed, with particular reference to a series of Norwegian studies based on bilateral oral surgery. In this model, paracetamol has proved capable of reducing post-operative swelling by about 30%, while acetylsalicylic acid (in common analgesic doses) failed to reduce or even tended to increase swelling. Paracetamol is a recommendable alternative for reducing acute post-traumatic pain and swelling, while acetylsalicylic acid should be avoided. Non-steroidal anti-inflammatory drugs which efficiently reduce rheumatoid swelling may provide good pain relief, but the effect on an acute post-operative swelling is less impressive. In the oral surgical model, glucocorticoids reduced post-traumatic swelling by about 50% and provided better or at least as good pain relief as any tested non-steroidal anti-inflammatory drug, including paracetamol. Single dose or short-term administration of a glucocorticoid is recommended as an efficient and valuable means of reducing both pain and excessive inflammation in surgery and traumatology. Of practical implication in traumatology is the finding that, for both paracetamol and glucocorticoids, almost the same reductions were recorded in swelling and pain whether the drug was administered prior to surgery or 2-3 hours afterwards.
Also, here is the abstract for the other study I mentioned above:

PGs have been shown to modulate skeletal muscle protein metabolism as well as inflammation and pain. In nonskeletal muscle tissues, the over the counter analgesic drugs ibuprofen and acetaminophen function through suppression of PG synthesis. We previously reported that ibuprofen and acetaminophen inhibit the normal increase in skeletal muscle protein synthesis after high intensity eccentric resistance exercise. The current study examined skeletal muscle PG levels in the same subjects to further investigate the mechanisms of action of these drugs in exercised skeletal muscle. Twenty-four males (25 +/- 3 yr) were assigned to 3 groups that received the maximal over the counter dose of ibuprofen (1200 mg/d), acetaminophen (4000 mg/d), or a placebo after 10-14 sets of 10 eccentric repetitions at 120% of concentric 1 repetition maximum using the knee extensors. Preexercise and 24 h postexercise biopsies of the vastus lateralis revealed that the exercise-induced change in PGF(2alpha) in the placebo group (77%) was significantly different (P < 0.05) from those in the ibuprofen (-1%) and acetaminophen (-14%) groups. However, the exercise-induced change in PGE(2) in the placebo group (64%) was only significantly different (P < 0.05) from that in the acetaminophen group (-16%). The exercise-induced changes in PGF(2alpha) and PGE(2) were not different between the ibuprofen and acetaminophen groups. These results suggest that ibuprofen and acetaminophen have a comparable effect on suppressing the normal increase in PGF(2alpha) in human skeletal muscle after eccentric resistance exercise, which may profoundly influence the anabolic response of muscle to this form of exercise.
