M-Peg 3350
M-Peg 3350 Uses, Dosage, Side Effects, Food Interaction and all others data.
The primary mode of action is thought to be through the osmotic effect of polyethylene glycol 3350 which causes water to be retained in the colon and produces a watery stool. M-Peg 3350 induces as diarrhea which rapidly cleanses the bowel, usually within four hours.
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.

Uses
This is white powder for reconstitution. It is a synthetic polyglycol having an average molecular weight of 3350. M-Peg 3350 is an osmotic agent that causes water to be retained with the stool. M-Peg 3350 appears to have no effect on the active absorption or secretion of glucose or electrolytes.
M-Peg 3350 is used for the treatment of constipation. This should be used for 2 weeks or less or as directed by physician. M-Peg 3350 3350 is a prescription only laxative that has been prescribed by physician to treat constipation. This product should only be used by the person for whom it is prescribed.
M-Peg 3350 is also used to associated treatment for these conditions: Chronic Constipation, Constipation, Dry Eye Syndrome (DES), Dry Eyes, Occasional Constipation, Bowel preparation therapy, Eye lubrication
How M-Peg 3350 works
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.
Dosage
M-Peg 3350 dosage
The usual dose of M-Peg 3350 is 17 gm of powder per day (or as directed by physician) in a glass of water, juice, coke, coffee or tea. Each bottle of M-Peg 3350 is supplied with a cup that is used to measure 17 gm or 8.5 gm of laxative powder when filled upto the marked line.
It should always be taken by mouth. Measure the dose using the supplied cup, stir and dissolve in a glass of water, juice, coke, coffee or tea. Taking more than the prescribed dose may cause loss of fluid due to severe diarrhea.
Duration of Treatment
M-Peg 3350 achieves its best results when used between one and two weeks. It may be discontinued after several satisfactory bowel movements. Should unusual cramps, bloating, or diarrhea occur, consultation with physician is needed. M-Peg 3350 is intended for up to a two-week course of therapy. It should not be used for a longer time unless directed by a physician. After successfully completing the M-Peg 3350 therapy (usually between one and two weeks) discussion with a physician is needed to change lifestyle that may produce more regular bowel habits (adequate dietary and fluid intake, regular exercise).
Side Effects
Nausea, abdominal bloating, cramping and flatulence may occur. High doses may produce diarrhea and excessive stool frequency, particularly in elderly nursing home patients. Patients taking other medications containing polyethylene glycol have occasionally developed urticaria suggestive of an allergic reaction.
Toxicity
The oral LD50 of PEG 3350 in rats is 22000 mg/kg.
There is limited clinical information on the overdose of polyethylene glycols. Based on the pharmacological action of the compound, severe diarrhea may be suspected. Overdose of polyethylene glycols should be responded with symptomatic and supportive care.
Precaution
Patients with symptoms suggestive of bowel obstruction (nausea, vomiting, abdominal pain or distention) should be evaluated to rule out this condition before initiating M-Peg 3350 therapy. M-Peg 3350 should be administered after being dissolved in water, juice, coke, coffee or tea.
Interaction
No specific drug interactions have been demonstrated.
Food Interaction
- Avoid alcohol. Withdrawing from alcohol increases the risk of seizures, which is also caused by the drug.
- Avoid milk and dairy products.
- Avoid solid foods. Consume only clear liquids from the start of drug treatment until after the colonoscopy.
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.
Elimination Route
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.
Half Life
Following a two-day split-dosing regimen of an oral suspension containing 140 grams of PEG 3350 in healthy subjects, the mean half life was 4.1 hours.
Clearance
There is limited information on the clearance rate of polyethylene glycols.
Elimination Route
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.
Pregnancy & Breastfeeding use
Pregnancy: It is not known whether Polyethylene glycol can cause fetal harm when administered to a pregnant woman, or can effect reproductive capacity. Polyethylene glycol should only be administered to a pregnant woman if clearly needed.
Lactation: There is no information on the use of Polyethylene glycol while nursing. Consultation with a physician is necessary in case of breastfeeding.
Contraindication
Polyethylene glycol is contraindicated in patients with known or suspected bowel obstruction and patients known to be allergic to polyethylene glycol.
Acute Overdose
There have been no reports of accidental overdosage. In the event of overdosage diarrhea would be the expected major event. If an overdose of drug occurred without concomitant ingestion of fluid, dehydration due to diarrhea may result. Medication should be terminated and free water administered.
