PF-04457845 is a potent and exquisitely selective inhibitor of the enzyme fatty acid amide hydrolase (FAAH), with an IC50 of 7.2nM, and both analgesic and antiinflammatory effects in animal studies comparable to naproxen.[1]
It has been well tolerated in human trials even at high dose ranges with no evidence for cognitive dysfunction, and has completed Phase II clinical trials for the treatment of osteoarthritis,[1][2][3][4] but was found to be ineffective.[5]
