乳果糖是一种不可吸收、具有渗透活性的碳水化合物,由一分子半乳糖和一分子果糖缩合而成;其在小肠不吸收,在结肠经过肠道细菌作用分解为乳酸、醋酸及氢气。乳果糖作为渗透性泻药,对人体无害,可以有效调节结肠生理节律,广泛用于老年人、孕妇及儿童的便秘治疗;作为益生元也可促进双歧杆菌等有益菌生长,抑制致病菌如沙门氏菌生长,恢复便秘患者的肠道菌群稳态,从而改善肠道运动功能。乳果糖除了用于治疗便秘外,还可应用于肝胆
Lactulose is a non-absorbable, osmotically active carbohydrate that is formed by the condensation of one molecule of galactose with one molecule of fructose; it is not absorbed in the small intestine and is broken down into lactic acid, acetic acid, and hydrogen in the colon by intestinal bacteria. Lactulose, as an osmotic laxative, is harmless to the human body and can effectively regulate colonic circadian rhythms and is widely used in the constipation treatment of the elderly, pregnant women and children.

In addition to lactose for the treatment of constipation, but also can be applied to liver and gallbladder
