Mechanism of action

Sodium picosulfate is a prodrug that undergoes bacterial metabolism in the colon to produce an active metabolite that stimulates colonic smooth muscle contractions and increases intestinal motility. Magnesium citrate functions as an osmotic agent, increasing intraluminal fluid volume and promoting bowel evacuation. Together, these agents produce a synergistic laxative effect suitable for bowel cleansing.
