Flurbiprofen Aspirin

Aspirin 1.3 to 3.6 g daily more than halved the serum levels of ibuprofen 800 mg to 2.4 g daily, without affecting salicylate levels. There was little additional clinical benefit from the combination. Similarly, aspirin reduced the AUC of flurbiprofen by about two-thirds, but without any clear changes in clinical effectiveness. The pharmacokinetics of the aspirin were unchanged by flurbiprofen. Aspirin 3.9 g daily also virtually halved the AUC of fenoprofen 2.4 g daily,and reduced the AUC of ke-toprofen 200 mg daily by about one-third. The AUC of naproxen was only minimally reduced (by 10 to 15%). Choline magnesium trisalicylate increased the clearance of naproxen by 56% and decreased its serum levels by 26% in one study. ...

Nonsteroidal Antiinflammatory Drugs. Nonsteroidal antiinflammatory dmgs (NSAIDs) include, among the numerous agents of this class, aspirin (acetylsaflcyhc acid), the arylacetic acids indomethacin and sulindac, and the arylpropionic acids, (5)-(147) and (R)-(148) ibuprofen, (5)-(149) and (R)- (150), flurbiprofen naproxen (41), and fenoprofen (see Analgesics, antipyretics, and antiinflammatory agents Salicylic acid and related compounds). 

The drugs like ibuprofen, flurbiprofen, ketoprofen etc. possess antiinflammatory property similar to aspirin but toxicity and adverse effects are fewer and of lesser intensity. These preparations alone and in combination with other NSAIDs are used for treatment of inflammatory disorders.

The efficacy of flurbiprofen at dosages of 200-400 mg/d is comparable to that of aspirin and other NSAIDs in clinical trials for patients with rheumatoid arthritis, ankylosing spondylitis, gout, and osteoarthritis. It is also available in a topical ophthalmic formulation for inhibition of intraoperative miosis. Flurbiprofen intravenously has been found to be effective for perioperative analgesia in minor ear, neck, and nose surgery and in lozenge form for sore throat.

Flurbiprofen is indicated for the acute or long-term treatment of rheumatoid arthritis and osteoarthritis. It is a potent inhibitor of prostaglandin synthetase (see Figures 13 and 14). Flurbiprofen is absorbed well orally, is bound to plasma proteins to the extent of 99%, is metabolized in the liver to pharmacologically active metabolites, and the metabolites are excreted in the urine. Flurbiprofen increases the actions of oral anticoagulants and decreases the effectiveness of diuretics. Flurbiprofen is contraindicated in patients who are allergic to aspirin (see also Table 12).
