Portalak is a laxative that stimulates intestinal motility.

Pharmacological properties

Pharmacodynamics

Portalac is a laxative with a hyperosmotic effect. Its mechanism of action is due to the influence of lactulose on the potentiation of the reproduction process in the intestine of Lactobacillus acidophilus and Lactobacillus bifidus, which causes a decrease in acidity in the lumen of the large intestine and the activation of its peristalsis. Along with the stimulation of intestinal motility, lactulose improves the absorption of phosphates and calcium salts, excretion of ammonium ions, and slows down the growth of Salmonella in the large intestine. Against the background of taking Portalak, the volume of feces increases and their softening occurs. The syrup does not directly affect the mucous membrane and smooth muscles of the large intestine.

The effect of lactulose helps to reduce the formation of nitrogen-containing toxic substances in the proximal colon and their absorption into the systemic circulation. The level of ammonium ions in the blood decreases by 25-50%, the severity of hepatic encephalopathy decreases, the patient's mental state improves and electroencephalography is normalized.

After taking the syrup inside, the therapeutic effect occurs as the drug passes through the gastrointestinal tract (GIT) for 24-48 hours.

Pharmacokinetics

After oral administration, lactulose is practically not absorbed from the gastrointestinal tract, no more than 3% of the dose taken is absorbed.

While taking vitamins, their absorption is not reduced.

Portalak is not addictive.

Due to the insignificant systemic effect of lactulose for elderly patients, with renal or hepatic insufficiency, dosage adjustment is not required.
