Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, particularly COX-1 and COX-2, thereby reducing prostaglandin synthesis and inflammatory responses. In the context of Visual Snow Syndrome, naproxen may help modulate neuroinflammatory processes and potentially alleviate symptoms by reducing central nervous system inflammation and pain signaling.
