Abstract
- BACKGROUND/AIMS
Ciprofloxacin has been widely prescribed for acute infectious diarrhea. However, the resistance to this drug is increasing. Rifaximin is a novel but poorly absorbed rifamycin derivative. This study evaluated and compared the efficacies of rifaximin and ciprofloxacin for the treatment of acute infectious diarrhea.
METHODS
We performed a randomized controlled multicenter study in Korea. Patients with acute diarrhea were enrolled and randomized to receive rifaximin or ciprofloxacin for 3 days. The primary efficacy endpoint was the time to last unformed stool (TLUS). Secondary endpoints were enteric wellness (reduction of at least 50% in the number of unformed stools during 24-hour postenrollment intervals), general wellness (subjective feeling of improvement), and proportion of patients with treatment failure.
RESULTS
Intent-to-treat analysis (n=143) showed no significant difference between the rifaximin and ciprofloxacin groups in the mean TLUS (36.1 hours vs 43.6 hours, p=0.163), enteric wellness (49% vs 57%, p=0.428), general wellness (67% vs 78%, p=0.189), or treatment failure rate (9% vs 12%, p=0.841). The adverse events did not differ significantly between the two groups.
CONCLUSIONS
These results suggest that rifaximin is as safe and effective as ciprofloxacin in the treatment of acute infectious diarrhea.
