QUICK LINKS

Naproxen sodium salt, a derivative of naproxen, functions by inhibiting the activity of cyclooxygenase (COX), an enzyme necessary for the biosynthesis of prostaglandins and thromboxanes from arachidonic acid. It reversibly binds to the active site of COX, preventing the conversion of arachidonic acid to prostaglandin H2. These molecules play key roles in inflammation and pain signaling pathways. By blocking COX enzymes, specifically COX-1 and COX-2, naproxen sodium effectively reduces the production of these pro-inflammatory mediators. This makes it useful in research studies focusing on inflammatory processes and pain mechanisms.
