COX2 - Inducible, inflammatory response
How does acetaminophen differ from other drugs?

What are the anti-inflammatory effects of asprin?
Nonselective inhibitor or COX isoforms
Irreversibly inhibits COX and platelet aggregation
What are the analgesic effects of asprin?
Most effective in reducing pain of mild to moderate intensity through reducing inflammation
What are the antipyretic effects of asprin?

Lower liability for GI upset
No impact on platelet aggregation though
What are some of the COX-2 selective inhibitors?
Celecoxib
Etoricoxib
Meloxicam
What are the characteristics of acetaminophen?
Weak inhibitor of COX enzymes
Central direct analgesic effects
