Medication Description: Forlax (Forlax)
The main component of the drug is a polymeric 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 up significantly and increases the content of fluid in the intestine, which leads to increased peristalsis. On the mechanism of action is similar to agar-agar, alginates (see. Sea kale). The drug in the intestine is not absorbed and excreted in the feces. The laxative effect occurs relatively slowly - 24-48 hours after taking the drug.
