Naproxen is a COX-1 and COX-2 inhibitor (IC50s: 8.72 and 5.15 μM, respectively in cell assay). Naproxen etemesil is a lipophilic and non-acidic prodrug of naproxen. It is hydrolyzed to pharmacologically active Naproxen once absorbed.

Naproxen is a well known nonsteroidal anti-inflammatory drug. Naproxen is an approximately equipotent inhibitor of COX-1 and COX-2 in intact cells (IC50s: 2.2 μg/mL and 1.3 μg/mL, respectively)[1].

Naproxen is shown to inhibit the time-courses of pain, fever, and PGE2 with similar potencies (IC50=27, 40, 13 μM). Naproxen exerts an anti-inflammatory and antifibrotic effect in the mouse model of bleomycin-induced lung fibrosis. Naproxen also downregulates TGF-β levels and Smad3/4 complex formation [2][3].
