← Human Body & HealthAn individual with rheumatoid arthritis takes a COX-2 selective inhibitor. Which outcome is most likely observed regarding prostaglandin production in the inflamed joints?
A)Increased thromboxane-A2 production
B)Reduced prostaglandin E2 synthesis✓
C)Elevated prostacyclin (PGI2) levels
D)Increased leukotriene B4 formation
💡 Explanation
COX-2 selective inhibitors reduce prostaglandin E2 synthesis because they specifically target cyclooxygenase-2, an enzyme crucial for PGE2 production in inflammation. Therefore, PGE2 production decreases, rather than an increase in thromboxane or other inflammatory mediators, which are regulated by different pathways.
