Page 7 of 11 ACTION AND CLINICAL PHARMACOLOGY Mechanism of Action Pharmacology:
Polyethylene Glycol 3350 is an osmotic agent which causes water to be retained with the stool. Essentially, complete recovery of Polyethylene Glycol 3350 was shown in normal subjects without constipation. Attempts at recovery of Polyethylene Glycol 3350 in constipated patients resulted in incomplete and highly variable recovery.
An in vitro study showed indirectly that Polyethylene Glycol 3350 was not fermented into hydrogen or methane by the colonic microflora in human feces Polyethylene Glycol 3350 appears to have no effect on the active absorption or secretion of glucose or electrolytes.
General Patients with symptoms suggestive of bowel obstruction, appendicitis or inflamed bowels (fever, nausea, vomiting, abdominal pain or distention) should consult a doctor to rule out these conditions before initiating LAX-A-DAY® therapy.
Overuse or extended use of any laxative may cause dependence for bowel function. Do not take any type of laxative for more than one (1) week, unless recommended by a physician. A laxative should not be taken within two (2) hours of another medicine because the desired effect of the other medicine may be reduced.
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. LAX-A-DAY® should be administered after being dissolved in approximately 250 ml of water, juice, soda, coffee, or tea.
LAX-A-DAY® may result in a potential interactive effect when used with starch-based food thickeners. The PEG ingredient counteracts the thickening effect of starch, effectively liquefying preparations that need to remain thick for people with swallowing problems.
This warning applies to all polyethylene glycol (PEG) containing-products.

CLINICAL TRIALS In two separate studies (1,3), 151 and 23 patients with less than 3 bowel movements per week were randomized to Polyethylene Glycol 3350, 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 was statistically superior to placebo during the first and second week of treatment. No clinically significant changes in blood chemistry, CBC, or urinalysis were observed. PEG laxative is safe and effective in the short term for the treatment of constipation.
Page 10 of 11 In a second study (2), 50 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 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 17gram dose of Polyethylene Glycol 3350 over placebo was demonstrated. There were no significant differences in laboratory changes or adverse experiences recorded between groups. PEG laxative is safe and effective in the short term treatment of constipation for ambulatory outpatients and is safe for long-term care patients.
In a fourth study (5), 304 patients with 3 bowel movements or less per week were randomized to 17 grams of Polyethylene Glycol 3350 or placebo for 6 months. 001). Similar efficacy was seen in a subgroup of 75 elderly subjects. 001). There were no significant differences in laboratory findings of adverse events, except for the gastrointestinal category where diarrhea, flatulence, and nausea were the […]

Page 5 of 11 Geriatrics (> 65 years of age):
There is no evidence for special considerations when LAX-A- DAY® is administered to elderly patients. If diarrhea occurs, LAX-A-DAY® should be discontinued. Monitoring and Laboratory Tests No clinically significant effects (1,2,3,5,6) on laboratory tests have been demonstrated.
In one study (1), CBC, blood chemistry, and urinalysis were performed after the 14-day treatment period. Laboratory data were compared by repeated measures of analysis of variance. 05 was considered statistically significant. No statistically or clinically significant differences between placebo and laxative groups were detected for laboratory measurements.
In another study (2), CBC, blood chemistry, and urinalysis were performed before and after each10-day treatment period. No clinically significant changes in laboratory measurements were seen. ADVERSE REACTIONS Adverse Drug Reaction Overview Occasionally, LAX-A-DAY® may cause nausea, abdominal bloating, cramping, diarrhea and/or gas.
High doses may produce diarrhea and excessive stool frequency, particularly in elderly nursing home patients. On rare occasions, hives and skin rashes have been reported which are suggestive of an allergic reaction. Patients taking other medications containing polyethylene glycol have occasionally developed urticaria suggestive of an allergic reaction.
DRUG INTERACTIONS No specific drug interactions have been demonstrated. A laxative should not be taken within two (2) hours of taking another medicine because the desired effect of the other medicine may be reduced.
