Lactitol, a Potential Second Generation Disaccharide Drug for the Treatment of Portal-Systemic Encephalopathy

  • M. Bührer

In 1966 the first report of the beneficial effects of lactulose in the treatment of chronic portal systemic encephalopathy was published.1 In the meantime, this drug has become accepted as drug of choice for this condition,2 but also some disadvantages of lactulose — available only as syrup with a very sweet taste and contamination by other sugars — have now been recognized. Unfortunately these features may lead to aversion against the drug, to nausea related to the hyperosmolarity of the syrup and consequently to suboptimal treatment. In view of these difficulties it is surprising that no analogs with more favorable physiochemical properties have as yet been investigated.
