Information about Ketoprofen

Ketoprofen is a nonsteroidal antiinflammatory drug (NSAID) used in treatment of acute pain and chronic arthritis. 

Liver safety of Ketoprofen

Ketoprofen 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 Ketoprofen

Ketoprofen (kee" toe proe' fen) belongs to the propionic derivative class of NSAIDs similar to naproxen and ibuprofen.  Like other NSAIDs, ketoprofen is a cyclo-oxygenase (Cox-1 and -2) inhibitor that blocks the formation of prostaglandins that are important in pain and inflammatory pathways.  Ketoprofen has analgesic as well as antipyretic and antiinflammatory activities.  Ketoprofen was approved in the United States in 1986 and is still widely used.  Current indications include chronic joint pain due to osteoarthritis and rheumatoid arthritis as well as mild-to-moderate acute pain and dysmenorrhea. 

Dosage and administration for Ketoprofen

The recommended dose in adults with chronic arthritis is 50 to 75 mg 3 or 4 times per day with a maximum dose of 300 mg daily.  Ketoprofen is available by prescription in the form of capsules or tablets of 25, 50 and 75 mg in both generic and trade formulations (Orudis, Oruvail, among others).  Extended release formulations of 100, 150 and 200 mg are also available for once daily dosing.  Ketoprofen is also available in over-the-counter formulations of 12.5 mg tablets for treatment of mild-to-moderate pain and dysmenorrhea. 

Side effects of Ketoprofen

As with other NSAIDs, ketoprofen is generally well tolerated, but side effects can include headache, dizziness, somnolence, gastrointestinal upset, nausea, abdominal discomfort, diarrhea, peripheral edema and hypersensitivity reactions.
