Bromfenac is a non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, particularly COX-2, thereby reducing inflammatory prostaglandin synthesis. In the context of Visual Snow Syndrome, it may help modulate neuroinflammatory processes and potentially mitigate cortical hyperexcitability associated with the condition, though its precise mechanism in this specific syndrome requires further research.
