Dufalac, 667 mg/ml syrup 500 ml

Disinotoxic, stimulates intestinal peristalsis, laxative.

Pharmacodynamics

Laxative drug. It has hyperosmotic laxative effect, stimulates intestinal peristalsis, improves absorption of phosphates and calcium salts and promotes removal of ammonium ions.

Lactulose is broken down by the intestinal flora of the large intestine into low-molecular organic acids, which lead to a decrease in pH and an increase in osmotic pressure and as a consequence an increase in the volume of intestinal content. 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 intestine by reducing the pH in the colon and osmotic effect, and reduction of nitrogenous toxic substances by stimulating bacteria that utilize ammonia for bacterial protein synthesis.

Lactulose as a prebiotic substance enhances the growth of beneficial bacteria such as bifidobacteria and lactobacilli, while suppression of potentially pathogenic bacteria such as Clostridium spp. and Escherichia coli becomes possible, resulting in a more favorable balance of intestinal flora.

Pharmacokinetics

The absorption is low. After oral administration it reaches the large intestine unchanged, where it is broken down by the intestinal flora.

It is completely metabolized when administered in doses up to 45-70 ml. When administered in higher doses it is partially excreted unchanged.

How to take, the dosage

The drug is intended to be taken orally as well as rectally.

Lactulose solution can be taken either diluted or undiluted.

In therapy with laxatives, it is recommended that sufficient fluids be taken (1.5-2 liters, which is equivalent to 6-8 glasses) per day.

For accurate dosing of the drug in bottles, use the measuring cup provided. When using the product in sachets, tear off the corner of the sachet and immediately take the contents.

Dose for the treatment of constipation or to soften stools for medicinal purposes

The daily dose of lactulose may be taken alone or divided in two using the measuring cup.

The starting dose may be adjusted to a maintenance dose after a few days, depending on how people respond to the medication. The laxative effect may appear 2-3 days after starting the drug.

*If the maintenance daily dose is less than 15 ml, it is recommended to use the drug in vials.

For accurate dosing in children under 7 years of age, it is recommended that the drug be used in vials.

Dose in the treatment of hepatic encephalopathy (adults)

For oral administration:

The initial dose: 3-4 times a day in 30-45 ml (2-3 sachets).

Then switch to an individualized maintenance dose so that soft stools are max 2-3 times a day.

For rectal administration:

In case of precoma or coma, the drug may be administered as an enema with retention (300 ml of drug/700 ml of water). The enema should be held for 30-60 minutes, and the procedure should be repeated every 4-6 hours until oral administration is possible.

The safety and effectiveness of the drug in children (under 18 years of age) has not been established due to lack of data.

Patients of advanced age and patients with renal or hepatic impairment

There are no specific dosing recommendations because the systemic effects of lactulose are negligible.
