Abstract: Presented herein are methods for treatment or prevention of opioid induced constipation by administration of oral compositions of methylnaltrexone. The methods are based, at least in part, on the identification of subjects that are particularly susceptible to such treatment and optimal dosages of such oral compositions to treat or prevent opioid induced constipation and, further, to minimize the occurrence of adverse events associated with such treatment.

Abstract: The application describes treatment of hepatic encephalopathy using gastrointestinal specific antibiotics. One example of a gastrointestinal specific antibiotic is rifaximin.

Abstract: The application describes treatment of hepatic encephalopathy using gastrointestinal specific antibiotics. One example of a gastrointestinal specific antibiotic is rifaximin. The instant application also provides methods for determining if a subject has a neurological condition or hepatic encephalopathy by determining the critical flicker frequency and/or the venous ammonia level of the subject at two or more time points. The invention further provides methods for treating these subjects.
