Alzheimer's disease (AD) is characterized by cerebral deposits of β‐amyloid (Aβ) peptides and neurofibrillary tangles (NFT) which are surrounded by inflammatory cells. Epidemiological studies have shown that prolonged use of non‐steroidal anti‐inflammatory drugs (NSAIDs) reduces the risk of developing AD and delays the onset of the disease. It has been postulated that some NSAIDs target pathological hallmarks of AD by interacting with several pathways, including the inhibition of cyclooxygenases (COX) and activation of the peroxisome proliferator‐activated receptor γ. A variety of experimental studies indicate that a subset of NSAIDs such as ibuprofen, flurbiprofen, indomethacin and sulindac also possess Aβ‐lowering properties in both AD transgenic mice and cell cultures of peripheral, glial and neuronal origin. While COX inhibition occurs at low concentrations in vitro (nM‐low μm range), the Aβ‐lowering …
