Information about Fenoprofen
Fenoprofen is a nonsteroidal antiinflammatory drug (NSAID) used in the treatment of acute pain and chronic arthritis.
Liver safety of Fenoprofen
Fenoprofen has been linked to a low rate of serum enzyme elevations during therapy and to rare instances of clinically apparent acute liver injury.
Mechanism of action of Fenoprofen
Fenoprofen (fen" oh proe' fen) belongs to the propionic derivative class of NSAIDs similar to naproxen, ketoprofen, flurbiprofen and ibuprofen. Like other NSAIDs, fenoprofen is a cyclo-oxygenase (Cox-1 and -2) inhibitor that blocks the formation of prostaglandins that are important in pain and inflammatory pathways. Fenoprofen has analgesic as well as antipyretic and antiinflammatory activities. Fenoprofen was approved in the United States in 1976 and is still in clinical use.
Clinical use of Fenoprofen
Current indications include chronic joint pain due to osteoarthritis and rheumatoid arthritis, as well as mild-to-moderate acute pain. The recommended dose in adults with pain is 200 mg every 4 to 6 hours. Higher doses are used for chronic arthritis, in the range of 400 to 600 mg 3 or 4 times per day, with a maximum dose of 3,200 mg daily. Fenoprofen is available by prescription only in the form of capsules or tablets of 200, 300, 400 and 600 mg in both generic and trade formulations (Nalfon).
Side effects of Fenoprofen
As with other NSAIDs, fenoprofen is generally well tolerated, but side effects can include headache, dizziness, somnolence, gastrointestinal upset, nausea, abdominal discomfort, diarrhea, peripheral edema and hypersensitivity reactions.
