Symptom improvement at 3 months

  • The Physician's Usage Study was a prospectively designed, open-label, retrospective analysis of 2499 patients who received ELMIRON® (pentosan polysulfate sodium) 300 mg/day
  • Patients' pain/discomfort scores were evaluated every 3 months
  • The end points of the study were the patient rating of overall change in pain from baseline and the change in pain/discomfort score from baseline


  • 29% of all patients (722 of 2499) enrolled reported symptom improvement at 3 months*
  • 61% of patients (722 of 1192) who continued treatment for 3 months experienced improvement in symptoms†‡
