The non-steroid anti-inflammatory drug tiaprofenic acid may cause cystitis that is very similar to PBS/IC. Most cases are reversible on withdrawal of the drug.

  • the authors conclude that tiaprofenic acid has caused at least 108 cases of cystitis and several of these patients underwent extensive urological surgery based on the assumption that they were suffering from chronic interstitial cystitis
  • most cases were reversible on withdrawal of tiaprofenic acid, but 10% of patients had residual symptoms
  • tiaprofenic acid caused a higher incidence of cystitis than any other NSAID and its withdrawal from the market should be considered according to the authors

• Tiaprofenic acid: an uncommon cause of cystitis often misdiagnosed as interstitial cystitis.
  Heritz DM, Thiessen JJ. Can J Urol 1996;3:202-5
  • the authors describe 8 cases of cystitis due to the use of the non-steroidal anti-inflammatory drug tiaprofenic acid but with an initial wrong diagnosis of interstitial cystitis
  • discontinuation of the drug will relieve symptoms usually within six weeks.

  • this study demonstrated upregulation of the chemokine, fractalkine, in the urinary bladder and specifically in the urothelium with CYP-induced cystitis
  • chemokines, and specifically, fractalkine, may be another class of neuromodulatory agents upregulated in the urinary bladder that can affect micturition function and sensory processing with cystitis and may represent novel, drug targets for cystitis
