Pharmacological properties
Lactulose has a laxative, hyperosmotic, hypoammoniaemic effect, stimulating intestinal motility, normalizes the intestinal microflora, improves the absorption of phosphates and calcium salts, promotes the excretion of protein breakdown products, is a breeding ground for lactic acid bacteria and promotes its development and reproduction. under its influence, the natural conversion of the drug in the large intestine to lactic, acetic, formic acid occurs completely, which contributes to an increase in acidity and osmotic pressure in the lumen of the large intestine, as well as an increase in intestinal motility (wave-like movements), an increase in the volume of feces, therefore, in the intestine binding of toxic decomposition products of protein compounds (ammonia). as a result, lactulose exhibits a mild laxative effect, without irritating the intestinal mucosa, and also reduces the content of toxic decomposition products of protein compounds in the blood, which are excreted from the body during the development of a laxative effect. also lactulose inhibits the growth of proteolytic microorganisms, including shigella, salmonella. the effect develops 24–48 hours after administration, its delay is due to the passage of the drug through the digestive tract. when ingested, lactulose is transformed in the intestine, decay products are excreted in the feces within 24–48 hours, no more than 3% of the drug is excreted unchanged in the urine.
