Mechanisms of Preventing Antibiotic-Associated Diarrhea and the Role for Probiotics

December 30, 2019

Overview

This trial aims to study the mechanisms behind how probiotics can prevent the effects of antibiotic-associated diarrhea (AAD). While probiotics are commonly used for preventing AAD, the mechanism has not been identified or backed up by sufficient research. Investigators hypothesize that probiotic yogurt will help protect against the development of AAD.

 

Study Information

In this study, investigators are looking for 60 participants who will be split into control and experimental arms. The experimental group will receive yogurt with BB-12 and Amoxicillin-Clavulanate while the control group will receive the same yogurt without the drugs. Participants will then be monitored for 30 days to see the effects.
