Detailed Description:

Data collection

Baseline characteristics
- demographic data; age, gender, BW, height
- cirrhosis; cause, duration, Child-Pugh score,complications of cirrhosis such as EV, ascites, hepatic encephalopathy, SBP etc.
- comorbidity such as DM, CVA
After randomization
- assessment of mental status (West-Haven criteria), Portal-systemic encephalopathy index (PSEI), number connection test, serum ammonia, asterixis at Day 1,3,7 and EEG at day 1,7
- blood chemistry such as CBC, BUN, Creatinine, electrolyte, LFT, coagulogram, BS at Day 1,3,7
- record adverse effect of drug such as nausea, vomiting, bloating.
- record diet, frequency of bowel movement and stool pH
- compliance
