Tiaprofenic acid Probenecid

NS AIDs ANTIGOUT DRUGS-PROBENECID T levels of indometacin, ketorolac and possibly dexketoprolien, ketoprofen, naproxen, tenoxicam and tiaprofenic acid Probenecid competitively inhibits renal metabolism of these NSAIDs Watch for signs of toxicity of these NSAIDs. Consider using an alternative NSAID. The manufacturers of ketorolac advise avoiding co-adminis-tration of ketorolac and probenecid... 

Probenecid reduces the clearance of dexketoprofen, diflunisal, in-dometacin (toxicity seen), ketoprofen, ketorolac, naproxen, sodium meclofenamate, tenoxicam and tiaprofenic acid and raises their levels. Ketorolac and probenecid are specifically contraindicated. The uricosuric effects of probenecid are not affected by in-dometacin but may be slightly reduced by sulindac. 

Probenecid appeared to reduce the urinary excretion of tiaprofenic acid in one healthy subject. The maximum urinary excretion rate was reduced by 66% and delayed by 2 hours.
