What this trial studies

This clinical trial evaluates the safety and efficacy of ondansetron in preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, a common complication that can lead to significant health issues. The study involves administering either ondansetron or a placebo to patients undergoing ERCP for suspected pancreato-biliary disorders. Participants will be monitored for the occurrence of pancreatitis following the procedure, with the aim of determining if ondansetron can effectively reduce this risk. The trial is designed for patients over 18 years old who meet specific health criteria.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with indications for ERCP due to suspected pancreato-biliary disorders and normal blood amylase and lipase levels.

Not a fit: Patients with uncontrolled diabetes, severe heart disease, or those who have previously had certain biliary procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of pancreatitis following ERCP, improving patient outcomes and safety.

How similar studies have performed: While the specific use of ondansetron for this purpose may be novel, similar studies have explored the prevention of post-ERCP pancreatitis with varying results.
