Pharmacological effect

Lavakol - a powerful laxative drug, a combination of which is designed to completely remove the contents of the intestine and restore water-electrolyte metabolism, caused by frequent stools.

Laxative effect provides the active substance - macrogol. The mechanism of its action is due to the attraction and retention of water, as a result of which it swells and grows in size. This contributes to a significant increase in the volume of intestinal contents and stimulation of peristalsis, ensuring rapid movement of fecal masses and their evacuation to the outside. The therapeutic effect occurs exclusively in the lumen of the intestine, so the absorption of the drug into the systemic bloodstream does not occur, it is excreted from the body in an unchanged form. It should be noted that the drug does not cause dehydration, because for swelling macrogol uses a liquid that was administered when it was taken, not sucking water from the stomach and intestines. Therefore, to ensure the mechanism of action requires strict adherence to recommendations for the use of Lavakola in terms of dissolving the powder in a certain amount of water.

When compared with other methods and means of compulsory bowel cleansing, the advantage of Lavakol is the simultaneous osmotic laxative effect, which causes complete cleansing of all parts of the intestine from food and stool, and replenishment of loss of fluid and salts caused by a frequent chair.

Lavakol or Fortrans - which is better?

Those wishing to clean the intestines are often asked the choice of the drug: domestic Lavakol or French Fortran? Given the relatively equal effectiveness of the first and second, Lavakol in this duel confidently wins by:

  1. The best taste qualities - the light salinity of Lavakola is more pleasant to people than the sweet-soda taste of Fortrans; accordingly, to drink three liters of solution, using the first drug, is much easier.
  2. The lower cost - its price is three times lower than the price of Fortrans.

Both drugs belong to the category of osmotic drugs and under the condition of one-time use practically do not disturb the balance of the intestinal microflora. But in case of abuse of osmotic laxatives, the leaching of useful microorganisms from the intestine is possible.
