Low-dose Naltrexone for Bladder Pain Syndrome
Trial ID or NCT#
Status
NOT RECRUITING
Purpose
Interstitial cystitis/Bladder Pain Syndrome (IC/PBS) is a constellation of symptoms of pelvic discomfort that includes both bladder-related pain as well as urinary frequency, urgency, and nocturia in the absence of an identifiable etiology that affects likely more than 5.4 million patients in the United States. There is a significant overlap in patients with IC/PBS and those with fibromyalgia and chronic pelvic pain syndrome. Low-dose naltrexone (LDN) has been shown to be effective for the treatment of chronic pain conditions. The primary aim of this study is to evaluate if LDN improves pain scores and lower urinary tract symptoms in patients with IC/PBS. A secondary aim is to show that it has a low adverse event profile.
