They must have a left ventricular ejection fraction of ≤40% documented in the past year. Exclusions include recent acute coronary events, severe kidney disease, certain heart procedures or conditions within specific timeframes, pregnancy, and known allergies to probenecid.Check my eligibility
What is being tested?
The study tests if probenecid, typically used for gout, can improve heart function in those with HFrEF when taken twice daily over six months. It will be compared against a placebo. Heart function will be measured by ultrasound; exercise capacity and health status through questionnaires are also evaluated.See study design
What are the potential side effects?
While not specified here, common side effects of probenecid may include allergic reactions, gastrointestinal discomforts like nausea or vomiting, dizziness, headaches and possible worsening of gout symptoms initially.
