Association of Elmiron (pentosanpolysulphate sodium) with pigmented maculopathy: An update for urologists and patients

Abstract

Introduction: Bladder pain syndrome (BPS) is a difficult disorder to diagnose and manage with a limited number of treatment options that have a good evidence base. Elmiron (pentosanpolysulphate sodium (PPS)) is recognised as a main second-line treatment option in many international guidelines. Recently published retrospective studies suggest that there is an association between Elmiron and pigmented maculopathy, a rare disease associated with visual impairment. Objectives: To review the known literature on Elmiron and pigmented maculopathy and alternative oral pharmacotherapy options for BPS. To promote awareness on this topic and aid urologists in managing Elmiron prescription. Methods: We reviewed the most commonly used oral treatments for BPS, in particular Elmiron, the current evidence to support this association with eye disease and its position in the management pathway of this complex condition. Conclusions: Recent retrospective longitudinal studies have demonstrated an association of Elmiron with pigmented maculopathy. However, as yet the exact nature of this relationship is unknown. Nevertheless, Elmiron remains an important part of the treatment pathway for BPS. We suggest clinicians should fully inform patients of this association, including patients who have been previously comenced on Elmiron. There should be ongoing and continuing reviews of all treatments to review its efficacy in indiviual patients. Level of evidence: Not applicable
