Mechanism of action

Sodium picosulfate is a prodrug that is metabolized by colonic bacteria into bis-(p-hydroxyphenyl)-pyridyl-methane, which acts as a stimulant laxative on the colon. Magnesium citrate acts as an osmotic agent, drawing water into the intestinal lumen to increase stool bulk and promote evacuation. Together, these components provide rapid and effective bowel cleansing prior to diagnostic or surgical procedures.
