Description

Lactulose is a synthetic disaccharide which is metabolised by gastro-intestinal bacterial flora to low molecular weight acids (chiefly lactic and acetic acids). There is no endogenous metabolising enzyme in the human gut. Its mode of action in constipation is as an osmotic agent producing soft stools.
