how does MICROLAX work?

  • MICROLAX MACROGOL 5.9 g, powder for oral solution is an iso-osmotic laxative, mixture of macrogol 3350 and electrolytes.
  • High molecular weight macrogols (3350) are long linear polymers on which water molecules are retained by hydrogen bonds. When administered orally, they cause an increase in the volume of intestinal fluids.
  • MICROLAX MACROGOL 5.9 g, powder for oral solution, mixture of macrogol 3350 and electrolytes, maintains an iso-osmotic liquid flow over the entire length of the intestinal tract.
  • The volume of unabsorbed intestinal fluid is responsible for the laxative properties of the solution.
