title: Lactulose (cephulac) in portosystemic encephalopathy.
abstract: Lactulose is a synthetic disaccharide that lowers elevated blood ammonia levels and improves symptoms in patients with portosystemic encephalopathy. It is generally well tolerated and appears to be a suitable alternative to neomycin sulfate for maintenance therapy to prevent recurrent attacks and to improve protein tolerance.
