What this Trial Is About

The goal of this clinical trial is to learn how rifaximin 200 mg is processed in the body (pharmacokinetics) in children 6 to 11 years old with acute diarrhea that may be caused by bacteria. It will also learn about the safety and effectiveness of rifaximin when given with oral rehydration therapy (ORT) compared with ORT alone. The main questions it aims to answer are: How does rifaximin 200 mg move through and leave the body in children with acute diarrhea? Is rifaximin safe for children in this age group? Does rifaximin plus ORT help resolve diarrhea faster than ORT alone? Researchers will compare rifaximin plus ORT to ORT alone to see if adding rifaximin improves outcomes. Participants will: Take one rifaximin 200 mg tablet + ORT three times a day for 3 days or receive ORT alone Receive oral rehydration therapy according to the investigator's standard of care Attend up to 4 clinic visits over 5 days and receive 4 follow-up phone calls Provide blood samples on Day 1 and Day 3 for pharmacokinetic testing (rifaximin group only) Provide stool samples to identify bacterial pathogens Keep a diary of stool frequency and consistency to help determine when diarrhea resolves Be monitored for side effects, vital signs, and laboratory changes
