Mechanism of action

Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) that blocks COX-1 and COX-2 enzymes, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever. Codeine phosphate is an opioid analgesic that binds to mu-opioid receptors in the central nervous system to modulate pain perception. The combination provides synergistic pain relief for moderate to moderately severe pain conditions.
