Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colon lavage solution that osmotically induces diarrhea to cleanse the colon.
Sodium picosulfate is a stimulant laxative that is converted by colonic bacteria to the active metabolite bis-(p-hydroxyphenyl)-pyridyl-2-methane, which acts on the colonic mucosa to stimulate peristalsis and increase water and electrolyte secretion. Magnesium oxide and citric acid react in solution to form magnesium citrate, an osmotic laxative that draws water into the intestinal lumen, increasing stool volume and promoting bowel evacuation.
Oral: 4 L (or 240 mL every 10 minutes) administered the evening before colonoscopy; alternatively, 2 L (or 240 mL every 10 minutes) plus 2 L of clear liquids given in split doses (first 1-2 L evening before, remaining in morning of procedure).
Adults: 10 mg sodium picosulfate, 3.5 g magnesium oxide, and 10.97 g anhydrous citric acid (reconstituted in water) as a single oral dose, followed by clear liquids. Two doses may be used in a split-dose regimen: first dose evening before procedure, second dose day of procedure at least 5 hours prior.

Not applicable; systemic absorption is negligible (plasma levels below detection limits). Clinical effect is localized to gastrointestinal tract.
Sodium picosulfate active metabolite BHPM: terminal half-life approximately 7.4 hours; clinical duration of laxative effect extends beyond half-life due to colonic residence.
Primarily fecal (approximately 95%) as unabsorbed polyethylene glycol; negligible renal excretion (<5%) as intact polymer.
Sodium picosulfate is primarily excreted in feces (biliary/fecal elimination) as active metabolite BHPM; <5% renal. Magnesium oxide is excreted renally as magnesium ions; absorbed magnesium is eliminated via kidneys. Anhydrous citric acid is metabolized in the Krebs cycle; minimal renal excretion.
