Description

Dufalac Pharmacodynamics
It has a hyperosmotic laxative effect, stimulates intestinal peristalsis, improves absorption of phosphates and Ca2+ salts, promotes excretion of ammonium ions.
Lactulose is broken down by the intestinal flora of the large intestine into low-molecular organic acids, which leads to a decrease in pH and an increase in osmotic pressure and, consequently, an increase in the volume of intestinal contents. These effects stimulate intestinal peristalsis and influence the consistency of the stool. As a result, the physiological rhythm of emptying the large intestine is restored.
In hepatic encephalopathy, the effect is attributed to suppression of proteolytic bacteria by increasing the number of acidophilic bacteria (such as lactobacilli), conversion of ammonia into an ionic form by acidifying the contents of the colon, emptying the bowel due to lower pH in the colon and osmotic effect, and reducing nitrogenous toxic substances by stimulating bacteria that utilize ammonia for bacterial protein synthesis.
Lactulose as a prebiotic enhances the growth of beneficial bacteria such as bifidobacteria and lactobacilli, while inhibiting the growth of potentially pathogenic bacteria such as Clostridium and Escherichia coli, resulting in a more favorable balance of intestinal flora.

Indications
– Constipation: regulation of the physiological rhythm of colon emptying;
– Stool softening for medical purposes (hemorrhoids, conditions after colon and anal surgery);
– Liver encephalopathy: treatment and prevention of hepatic coma or precoma
