Pirprofen is a non-steroidal anti-inflammatory drug, related structurally to drugs such as ibuprofen, ketoprofen and naproxen. Pirprofen was introduced by Ciba-Geigy in 1982 as a treatment for rheumatic diseases. In 1990 due to adverse effects, including some cases of fatal liver toxicity the manufacturers decided to discontinue marketing it worldwide. Pirprofen proved to be useful in the management of both rheumatoid arthritis and osteoarthritis and as an analgesic. In doses of 600-800 mg/d, pirprofen has been found to be as effective as, but not superior to, aspirin 3.6 g/d in relieving the more common symptoms of rheumatoid arthritis. Pirprofen is as effective as, but not superior to, other available NSAIDs in terms of efficacy, tolerability, and incidence of adverse effects. The recommended dosage in osteoarthritis is 450-600 mg/d.

Sample Use Guides

Published clinical trials indicate that pirprofen 600 to 1200 mg/day as 2 or 3 divided doses is a suitable alternative to usual therapeutic dosages of aspirin, flurbiprofen, ibuprofen, indomethacin, ketoprofen, naproxen, piroxicam and sulindac in the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, musculoskeletal disorders and non-articular rheumatism. In patients with acute postsurgical, trauma or cancer pain, single oral or intramuscular doses of pirprofen 200 to 400mg provide equivalent analgesic activity to usual therapeutic doses of aspirin, diflunisal, ketoprofen, noramidopyrine, paracetamol and pentazocine.

In Vitro Use Guide
Curator's Comment: Pirprofen, racemic 2-[3-chloro-4(3-pyrrolinyl) phenyl] propionic acid, was evaluated for its ability to inhibit the conversion of arachidonic acid into prostaglandin E2 by sheep seminal vesicle prostaglandin synthase in vitro.
The compound proved to be a potent inhibitor with a Ki value of about 1.2 uM.
