NSAIDs and acetaminophenibuprofen, naproxen and aspirin are all NSAIDs (non-steroidal anti inflammatory drugs.) Among other actions their main mechanism of action is to block a group of enzymes called COX (cyclo-oxygenase) enzymes. They reduce pain (analgesic), reduce high temperatures (antipyrexial), reduce swelling (anti-inflammatory) and make the blood less likely to clot (antithrombolic). As they're all in the same group, they all have similar side effects and risks, however the severity of each side effect varies across the drugs, for instance naproxen is less likely to cause heart problems than ibuprofen. Common side effects include gastric irritation (the reason they should be taken with food) and bleeding. Other drugs in this group include diclofenac and the coxibs (however these have more specific action).

Acetaminophen (paracetamol), is not an NSAID and acts via different mechanisms. It shares the analgesic and antipyretic properties of the NSAIDs, but in not anti-inflammatory or antithrombolic. It is broken down in the body by the liver, unlike NSAIDS which are removed via the kidneys, and have very different side effects.

Acetaminophen can be taken with an NSAID, however you should not take more than one NSAID at a time.

What was your hypothesis when you did which pain reliever dissolves the fastest?

i recently did this project and our hypothesis was that out of our four pain relievers (naproxen sodium - like aleve, acetaminophen - like tylenol, aspirin, and ibuprofen - like motrin), naproxen sodium would take the longest to dissolve while ibuprofen and acetaminophen would dissolve the quickest. our hypothesis was proved partially right: naproxen sodium did take the longest to dissolve. however, aspirin was the quickest, not acetaminophen and ibuprofen.

Is there aspirin in Aleve?

No, Aleve (naproxen sodium) does not contain aspirin; however, it is an NSAID and is an anti-inflammatory, as is aspirin. It does have some blood thinning properties and can upset the stomach, as can aspirin. They should not be taken together. No. The active ingredient in Aleve is naproxen (in the prescription meds, Naprosyn and Anaprox).


Is ibuprofen also Tylenol?

It's neither - Aspirin is acetylsalicylic acid and Tylenol(brand name) is acetaminophen -Ibuprofen and aspirin belong to the same drug class - Non-steroidal anti-inflammatories (NSAIDS), while acetaminophen is an analgesic (pain reliever) -they can have similar effects on the body using differing mechanisms.


What other aspirins can you take that do not have aspirin?

Aspirin is Aspirin. When people say "Take an Aspirin," they are actually referencing the drug itself. If your question is "What other Over the Counter pain reliever/blood thinners can I take that do not contain Aspirin," then I would have to ask what purpose you need it for. As for Pain Relievers, anything containing Acetaminophen/Paracetamol (Tylenol), Ibuprofen (Advil), or Naproxen Sodium (Aleve) may be of some help. If you're looking for an OTC Blood Thinner, Aspirin is your best bet, however Ibuprofen may also be of some help.
