Flufenamic acid (FFA) is a member of the anthranilic acid derivatives (or fenamate) class of nonsteroidal anti-inflammatory drugs (NSAIDs).[1]: 718  Like other members of the class, it is a cyclooxygenase (COX) inhibitor, preventing the formation of prostaglandins.[2] FFA is known to bind to and reduce the activity of prostaglandin F synthase and activate TRPC6.[3]

It is not widely used in humans as it has a high rate (30–60%) of gastrointestinal side effects.[4]: 310  It is generally not available in the US.[2] It is available in some Asian and European countries as a generic drug.[5]

Scientists led by Claude Winder from Parke-Davis invented FFA in 1963, along with fellow members of the class, mefenamic acid in 1961 and meclofenamic acid in 1964.[1]: 718 

Although flufenamic acid was at one time informally referred to as "Fluffy" (see history cache), this pet name could also refer to .
