Description of the medicine: Forlax (Forlax)
The main component of the drug is a polymer substance - macrogol 4000 or polyethylene glycol of the general formula.
This high molecular weight compound has the ability to attract and retain a significant amount of liquid (water); when taken orally, it swells significantly and increases the fluid content in the intestines, which leads to increased peristalsis. By the mechanism of action is similar to agar-agar, alginates (see. Sea kale). The drug in the intestine is not absorbed and excreted in feces. Laxative effect occurs relatively slowly - 24-48 hours after taking the drug.
Assign to adults with constipation 10 g (1 sachet) 1-2 times a day (the contents of the sachet are previously dissolved in one glass of water).
Forlax is usually well tolerated. In some cases, abdominal pain, diarrhea (with increased doses) are possible.
The drug is contraindicated in inflammatory bowel diseases (ulcerative colitis, Crohn’s disease, etc.), intestinal obstruction, severe heart failure, in childhood.

Note. Macrogol 4000 (polyethylene glycol) is also used as a component of eye drops that replace tear fluid (Hypo Tears) - see also Lacrisin.
Polyethylene glycol of different molecular weights is used as an aid in the manufacture of various finished dosage forms.
