Interactions with other drugs No study has been carried out. 4.6. Pregnancy and breast feeding Studies in animals have not shown a teratogen effect. In the absence of a teratogenic effect in animals, a malformative effect on the human species is not expected. To date the substances responsible for malformations in the human species have been shown to be teratogenic in animals during well-conducted studies on two species. In clinical studies there are no particular malformative or fetotoxic effects appeared to date. However monitoring pregnancies exposed to lactulose is not enough to rule out any risk. Given the data, the use of lactulose is not recommended during pregnancy unless necessary. 4.7. Effects on the ability to drive and operate machinery Not applicable. 4.8.

Pharmaco-dynamic properties OSMOTIC LAXATIVE. HYPO AMMONIA. Code ATC: A06AD11 (A: digestive and metabolism). 1. Lactulose increases hydration and the the volume of colic. 2. In the colon, the transformation of lactulose into organic acids lowers the pH of the colon content, thus reducing the absorption of ammonia. 5.2. Pharmacokinetics properties Lactulose, a synthetic disaccharide, passes through the upper parts of the digestive tract without modification and without resorption. In the colon, under the effect of the local saccharolytic flora, it is transformed into organic acids (lactic and acetic), which are eliminated in the stool. 5.3.
