efficacy and safety of sinquanon for prevention of antibiotic-associated diarrhea in adults

Conditions: Antibiotic-associated Diarrhea

Summary: the purpose of this study is to evaluate the efficacy of a probiotic, sinquanon, on the reduction of the occurrence of diarrhea associated with antibiotic use in adults.

the study aims to evaluate the efficacy of a specialized multi-strain probiotic, sinquanon, on the reduction of the incidence of antibiotic-associated diarrhea in adults and to demonstrate the benefit of administering the specialized multi-strain probiotic as a routine add-on to antibiotic therapy on prevention of antibiotic-associated diarrhea in adults who take antibiotics in the outpatient setting.
