Polyethylene glycol is indicated for use as an over-the-counter osmotic laxative to relieve occasional constipation. When used in combination with sodium ascorbate, sodium sulfate, ascorbic acid, sodium chloride and potassium chloride, it is used for cleansing of the colon in preparation for colonoscopy in adults.
FDA Label
The osmotic effect of PEG produces a copious watery diarrhea. The onset of action of PEG 3350 is about 1 to 2 hours after oral ingestion. The colonic transit of polyethylene glycol occurs in a dose-dependent manner. When used for bowel preparation before colonscopy, electrolytes are typically added in the oral solution to prevent dehydration and electrolyte disturbances. As an over-the-counter laxative, the OTC product does not contain any salts that can be absorbed. In a study involving healthy subjects, PEG 3350 had negligible effects on colonic fluid absorption or with the ability of the colonic mucosa to generate and sustain steep electrochemical gradients.

Absorption
Following a two-day split-dosing regimen of an oral suspension containing 140 grams of PEG 3350 in healthy subjects, the mean Cmax was 2.7 mcg/mL and the mean Tmax was 3 hours. Typically, polyethylene glycols with a high molecular weight are poorly absorbed from the gastrointestinal tract following oral administration.
Route of Elimination
Following administration of an oral suspension containing 140 grams of PEG 3350 in healthy subjects, up to 85% to 99% of the compound was excreted in the feces.
Volume of Distribution
Following a two-day split-dosing regimen of an oral suspension containing 140 grams of PEG 3350 in healthy subjects, the mean volume of distribution was 48,481 L.
Clearance
There is limited information on the clearance rate of polyethylene glycols.
During 4 hr following iv dose of (14)C-ethylene glycol, urinary excretion of (14)C was more rapid from rats (38%) than from rhesus monkeys (10%), but excretion in expired air was similar (about 5%). Some (14)C entered body carbon pool. Oral dose was also more rapidly excreted by rats.

The proportion of administered (14)C (as ethylene glycol) excreted in urine of rats varied with dosage, being 21% at dose of 0.1 g/kg and 78% at dose of 7.5 g/kg. Distribution of radioactivity 24 hr after administration ...to rats was highest in bones (2-10%); highest in muscle of rabbits (3.4%), although liver contained 1.4 and bone 1.7% of dose.

A dose-dependent change was observed in disposition of (14)C-labeled ethylene glycol after iv administration of 20, 200, 1000, and 2000 mg/kg to Fischer 344 rats. Part of the dose was expired as carbon dioxide and decreased from 39% at 20 and 200 mg/kg to 26% at 1000 and 2000 mg/kg, while urinary excretion of radiocarbon increased from 35 to 56%. As dose increased from 20 to 2,000 mg/kg increases in urinary (14)C was almost entirely attributable to (14)C-glycolate, which comprised 20% of dose in 24 hrs at two higher dose levels and only 2% at lower doses. Blood clearance of (14)C occurred in initial rapid phase (half-life, 3-5 hr), when plasma comprised predominantly of ethylene glycol, that persisted for 12 hrs at 20 mg/kg and 30 hr at 2000 mg/kg administered iv to Fischer 344 rats.

Polyethylene glycol is a metabolically inert laxative that does not undergo intestinal enzymatic degradation or bacterial metabolism.
Multiple metabolites contribute to the toxic effects. Glycolaldehyde and glyoxylate are more toxic than glycolate, although the latter is the only metabolite that accumulates in appreciable amounts, owing to the rate-limiting effect of lactate dehydrogenase or glycolate oxidase. Glyoxylate can be converted to numerous metabolites, the most toxic of which is oxalic acid (oxalate). Oxalate complexes with calcium to form calcium oxalate crystals, which are deposited in various tissues.

Although oxalate normally is a minor metabolic product of ethylene glycol metabolism, urinary oxalate crystals are a common, but not invariable, feature of ethylene glycol intoxication. There are two forms of urinary calcium oxalate crystals: the octahedral or tent-shaped form of the dihydrate crystals, and the prism or dumbell-shaped monohydrate. The latter form is stable under normal physiologic conditions; the dihydrate form appears only during high urinary calcium and oxalate concentrations, as seen in ethylene glycol poisoning. The dihydrate form can transform into the monohydrate form.

Rabbits and rats were given doses of 0.1-2.0 g/kg /of (14)C-ethylene glycol/. Rabbits received the doses orally or by subcutaneous injection, rats were given subcutaneous injections. In rabbits and rats, approximately 20% to 30% of the (14)C label from ethylene glycol (14)C was eliminated in the urine. Metabolites found in the 24-hr urine incl unchanged ethylene glycol (6.0 to 15.1%) and a trace of oxalic acid (0.1%

Hepatic metabolism occurs through successive oxidations by the enzyme alcohol dehydrogenase. The elimination half life of ethylene glycol in the absence of alcohol dehydrogenase inhibitors is 2.5 to 3.0 hours. If alcohol dehydrogenase inhibitor therapy is instituted before the development of renal insufficiency, the elimination half life lengthens to approximately 17 hours, mostly via normal renal elimination. In the presence of fomepizole, the elimination half life is increased to approximately 20 hours.

Osmotic laxatives contain substances that are poorly absorbable and draw water into the lumen of the bowel. Polyethylene glycol functions is an osmotic laxative that causes increased water retention in the lumen of the colon by binding to water molecules, thereby producing loose stools.
Ethylene glycol is metabolized by alcohol dehydrogenase to glycoaldehyde, which is then metabolized to glycolic, glyoxylic, and oxalic acids. These acids, along with excess lactic acid are responsible for the anion gap metabolic acidosis. Oxalic acid readily precipitates with calcium to form insoluble calcium oxalate crystals. Tissue injury is caused by widespread deposition of oxalate crystals and the toxic effects of glycolic and glyoxylic acids.
