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.
Osmotic laxative that retains water in the bowel lumen via osmotic gradient, inducing diarrhea to cleanse the colon. Sodium sulfate, potassium sulfate, and magnesium sulfate are poorly absorbed, creating an osmotic effect. Additionally, magnesium may stimulate cholecystokinin release.
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).
For bowel cleansing prior to colonoscopy: 3 packets (each packet contains 1.6 g magnesium sulfate anhydrous, 3.13 g potassium sulfate, and 1.5 g sodium sulfate) dissolved in water to make 16 ounces, followed by additional water: administer as a split-dose regimen (one 16-ounce solution the evening before and one 16-ounce solution on the day of the procedure).

Not applicable; systemic absorption is negligible (plasma levels below detection limits). Clinical effect is localized to gastrointestinal tract.
Not applicable as a systemic half-life; the drug acts locally in the gastrointestinal tract. For absorbed sulfate, elimination half-life is approximately 6-8 hours in patients with normal renal function.
Primarily fecal (approximately 95%) as unabsorbed polyethylene glycol; negligible renal excretion (<5%) as intact polymer.
Primarily renal excretion. Approximately 20% of sulfate is absorbed and excreted in urine; the remainder is eliminated fecally as unabsorbed drug. Potassium is mostly reabsorbed; excess is excreted renally.
