POLYETHYLENE GLYCOL 3350 DESCRIPTION
A white powder for reconstitution. Polyethylene Glycol 3350 NF (Polyethylene Glycol 3350
Powder For Oral Solution) is a synthetic polyglycol having an average molecular weight of
3350. The actual molecular weight is not less than 90.0 percent and not greater than 110.0
percent of the nominal value. The chemical formula is HO(C2H4O)nH in which n represents
the average number of oxyethylene groups. Below 55°C it is a free flowing white powder
freely soluble in water. Polyethylene Glycol 3350 NF is an osmotic agent for the treatment
of constipation.
CLINICAL PHARMACOLOGY
Pharmacology: Polyethylene Glycol 3350 NF is an osmotic agent which causes water to be
retained with the stool. Essentially, complete recovery of Polyethylene Glycol 3350 NF was
shown in normal subjects without constipation. Attempts at recovery of Polyethylene Glycol
3350 NF in constipated patients resulted in incomplete and highly variable recovery. In vitro
study showed indirectly that Polyethylene Glycol 3350 NF was not fermented into hydrogen
or methane by the colonic microflora in human feces. Polyethylene Glycol 3350 NF appears
to have no effect on the active absorption or secretion of glucose or electrolytes. There is no
evidence of tachyphylaxis.
CLINICAL TRIALS
In one study, patients with less than 3 bowel movements per week were randomized to
Polyethylene Glycol 3350 NF, 17 grams, or placebo for 14 days. An increase in bowel
movement frequency was observed for both treatment groups during the first week of
treatment. Polyethylene Glycol 3350 NF was statistically superior to placebo during the
second week of treatment. In another study, patients with 3 bowel movements or less per
week and/or less than 300 grams of stool per week were randomized to 2 dose levels of
Polyethylene Glycol 3350 NF or placebo for 10 days each. Success was defined by an
increase in both bowel movement frequency and daily stool weight. For both parameters,
superiority of the 17 gram dose of Polyethylene Glycol 3350 NF over placebo was
demonstrated.
POLYETHYLENE GLYCOL 3350 INDICATIONS AND USAGE
For the treatment of occasional constipation. This product should be used for 2 weeks or
less or as directed by a physician.
POLYETHYLENE GLYCOL 3350 CONTRAINDICATIONS
Polyethylene Glycol 3350 NF is contraindicated in patients with known or suspected bowel
obstruction and patients known to be allergic to polyethylene glycol.
WARNINGS
Patients with symptoms suggestive of bowel obstruction (nausea, vomiting, abdominal
pain or distention) should be evaluated to rule out this condition before initiating
Polyethylene Glycol 3350 NF therapy.
PRECAUTIONS
General
Patients presenting with complaints of constipation should have a thorough
medical history and physical examination to detect associated metabolic, endocrine and
neurogenic conditions and medications. A diagnostic evaluation should include a structural
examination of the colon. Patients should be educated about good defecatory and eating
habits (such as high fiber diets) and lifestyle changes (adequate dietary fiber and fluid
intake, regular exercise) which may produce more regular bowel habits.
Polyethylene Glycol 3350 NF should be administered after being dissolved in approximately
4 to 8 ounces of water, juice, soda, coffee or tea.
Information for patients
Polyethylene Glycol 3350 NF softens the stool and increases the
frequency of bowel movements by retaining water in the stool. It should always be taken by
mouth after being dissolved in 4 to 8 ounces of water, juice, soda, coffee, or tea. Should
unusual cramps, bloating, or diarrhea occur, consult your physician.
Two to 4 days may be required to produce a bowel movement. This product should be used
for 2 weeks or less or as directed by your physician. Prolonged, frequent or excessive use of
Polyethylene Glycol 3350 NF may result in electrolyte imbalance and dependence on laxatives.
Laboratory tests
No clinically significant effects on laboratory tests have been demonstrated.
Interactions
Drug interactions
No specific drug interactions have been demonstrated.
Carcinogenesis, mutagenesis, impairment of fertility
Long term carcinogenicity studies,
genetic toxicity studies or reproductive toxicity studies in animals have not been performed
with Polyethylene Glycol 3350 NF.
Pregnancy
Category C. Animal reproductive studies have not been performed with Polyethylene Glycol 3350 NF.
It is also not known whether Polyethylene Glycol 3350 NF can cause fetal harm when
administered to a pregnant woman, or can affect reproductive capacity. Polyethylene Glycol
3350 NF should only be administered to a pregnant woman if clearly needed.
Pediatric use
Safety and effectiveness in pediatric patients has not been established.
Geriatric use
There is no evidence for special considerations when Polyethylene Glycol
3350 NF is administered to elderly patients. In geriatric nursing home patients a higher
incidence of diarrhea occurred at the recommended 17 g dose. If diarrhea occurs
Polyethylene Glycol 3350 NF should be discontinued.
POLYETHYLENE GLYCOL 3350 ADVERSE REACTIONS
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.
DRUG ABUSE AND DEPENDENCE
Overdosage
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. The oral LD50 is > 50 gm/kg in mice, rats and rabbits.
POLYETHYLENE GLYCOL 3350 DOSAGE AND ADMINISTRATION
The usual dose is 17 grams (about 1 heaping tablespoon) of powder per day (or as directed
by physician) in 4 to 8 ounces of water, juice, soda, coffee, or tea. Each bottle of
Polyethylene Glycol 3350 NF is supplied with a dosing cup marked to contain 17 grams of
laxative powder when filled to the indicated line. Two to 4 days (48 to 96 hours) may be
required to produce a bowel movement.
