Pharmacological action

Due to the osmotic action of the laxative drug, intestinal motility stimulation is stimulated. The ability of the agent to hyperosmotic effect allows calcium compounds and phosphates to be easily absorbed, and ammonium to be excreted.

The microflora formed in the intestine decomposes the active ingredient of the medicament, lactulose, into a number of organic acids, causing a decrease in pH and an increase in the osmotic pressure. Why the volume of contents of intestines increases, its peristalsis is strengthened. As a result, the consistency of the feces changes - softens, and in the colon the restoration of the physiological rhythm associated with its emptying takes place.

In people suffering from hepatic encephalopathy or hepatic precoma, the effectiveness of the remedy is due to the fact that it creates an environment in the intestine that does not favor proteolytic bacteria( their development and reproduction).Due to Dufalac in the intestine, the growth of colonies formed by acidophilic bacteria is observed.

The contents of the intestine are acidified, which allows ammonia to transform into an ionic form. As a result, the pH of the intestine decreases, the osmotic effect occurs, the concentration of toxic nitrogen-containing compounds decreases( their formation is impeded by microorganisms that are capable of utilizing ammonia related to bacterial protein synthesis), the contents of the intestines are exported naturally. In addition, the drug suppresses the development of salmonella, shortens the time of isolation of bacteria.

Pharmacokinetics and drug interaction

The laxative has a low absorption. It, almost without being absorbed, reaches the large intestine, in which it undergoes splitting under the influence of microflora. If the dose does not exceed 45-70 ml, the drug is fully metabolized.

At high dosages, a portion of the lactulose is excreted without being altered.

Assigning the use of enteric medicines( such as 5-aminosalicylic acid), in which pH-dependent release, along with Dufalac, take into account the properties of lactulose. It reduces the pH of the environment in the intestines, and therefore, contributes to a change in the release of prescribed medications.

In therapeutic treatment of constipation and restoration of intestinal microflora to normal in pregnant and newborns( as in all children), it is advisable to use lactulose, the active substance of Dufalac. Lactulose is not found in nature, it is synthesized by subjecting it to "whey whey" or "reverse" by heat treatment, and is obtained from milk when making cheeses.

It follows that the syrup is a medicinal product of natural origin. He is safely prescribed to pregnant, nursing and babies from the moment of birth. The effect of lactulose is similar to that of "bifidus factor", a special component of breast milk.

Dufalac has a structure that does not undergo cleavage by enzymes that fill the digestive tract. The drug, without changing, reaches the large intestine, where it feeds useful bacteria. Colonies of microorganisms, feeding on lactulose, actively multiply and suppress harmful microbes.

The drug does not penetrate the bloodstream, so it does not reach the developing fetus, therefore, it does not adversely affect its health. Components of the syrup are processed not by the body, but by bacteria that colonize the intestinal space, which determines its absolute safety. Lactulose is not able to be split and absorbed. Therefore, the drug is prescribed regardless of the period of pregnancy and at the time of breastfeeding.

Increase the content of the intestine, increase peristalsis, restore the natural balance of microflora and the capacity of the intestines to help inflow fluid. The medicine is delicately, without causing damage to health, cleans the intestines, in the same way as natural dietary fibers.

Thanks to Dufalac, women have problems with defecation during pregnancy and the baby is born with a natural intestinal microflora. Because children perfectly tolerate the drug, it is prescribed even to the newborn. The main thing is to choose the right individual dosage.
Medication does not interfere with the absorption of vitamins and nutrients. Addiction to this laxative is not found. Therefore, he is prescribed courses and heals( if necessary) patients for a long time.
