A Comparison of Three Medications to Treat Diarrhea in Adults.
A comparison of three medications to treat diarrhea in adults.
This single (investigator) blind, randomized, 3-arm, parallel-group study design was selected
 to show non-inferiority of loperamide/simeticone caplets compared to chewable tablets in a
 heterogeneous subject population aiming at validity of results and reducing bias. The study
 will also compare the loperamide/simeticone combinations versus a probiotic (Saccharomyces
 boulardii) in the treatment of acute diarrhea in adults. Probiotics have been used for acute
 infectious diarrhea to reduce the duration and severity of the illness.
