Flobufen (VUFB 16066) is a non-steroidal anti-inflammatory agent and cyclooxygenase (COX) and 5-lipoxygenase (5-LOX) inhibitor agent. Flobufen inhibits alloantigen-driven cellular immune responses and stimulates phagocytosis of peritoneal cells. Flobufen can improve immunopathological disorders and has an inhibitory effect on rheumatoid arthritis.
