Difference between NSAID and acetaminophen

So, I've always known that Aspirin and Tylenol weren't the same exactly, but I really never understood why. And when I did, I would often forget the difference. Here's the breakdown:

Non-steroidal anti-inflammatory drug (Aspirin):

• reduces pain
• reduces fever
• reduces inflammation
• causes stomach irritation/damage (biggest disadvantage of this medication)
• inhibits the production of prostaglandins --> inhibits protection against acidity
• prostaglandins
• local hormones that transmit pain information to the brain
• modulate hypothalamic thermostat
• activate inflammatory response
• stimulates constriction and clotting of platelets
• involved with induction of labor
• involved with GI tract (inhibits acid synthesis and increases secretion of protective mucus)
• increases blood flow in kidneys
• bronchoconstrictor (used for asthma)
• reduces blood clot formation
• Aspirin is the only NSAID with an antiplatelet effect 
• Common types: Aspirin, Ibuprofen, Naproxen, Advil, Toradol, Motrin
• These drugs differ in their mechanism of action, although they accomplish the same task

Acetaminophen/Paracetamol (Tylenol):

• reduces pain
• reduces fever
• not indicated for anti-inflammatory purposes because it exhibits weak anti-inflammatory activity
• does NOT reduce blood clot formation
• better tolerated in those with gastric acid problems
• Common types: Tylenol, Genapap, Feverall, Actamin, Altenol, Aminofen, Anacin Aspirin Free, Apra

Mnemonics to help:

• Aspirin is NOT acetaminophen
• Acetaminophen = A for Analgesic!
