Pilot Study of Loop Diuretics Among Individuals Receiving Hemodialysis

Phase 2

Completed

Conditions: Chronic Kidney Disease Requiring Chronic Dialysis

Interventions: Drug: Furosemide (loop diuretic) Tablets

Registration Number: NCT04622709

Lead Sponsor: University of North Carolina, Chapel Hill

Brief Summary: Individuals with kidney failure receiving maintenance hemodialysis (HD) have high mortality rates, driven largely by cardiovascular causes. Volume-related factors are critical, modifiable contributors to cardiovascular complications. Reversing volume overload has been shown to improve blood pressure and cardiac remodeling. Use of loop diuretics may represent a pragmatic, low-cost, and low-burden strategy to improve outcomes in people receiving HD. Lack of data on optimal furosemide dosing, safety, and acceptability are barriers to expanded use. This study investigates whether oral furosemide is safe and effective at increasing urine volume in HD patients.
