CLINICAL PHARMACOLOGY
Pharmacology
Polyethylene Glycol 3350, USP is an osmotic agent which causes water to be retained with the stool. Essentially, complete recovery of Polyethylene Glycol 3350, USP was shown in normal subjects without constipation. Attempts at recovery of Polyethylene Glycol 3350, USP in constipated patients resulted in incomplete and highly variable recovery. In vitro study showed indirectly that Polyethylene Glycol 3350, USP was not fermented into hydrogen or methane by the colonic microflora in human feces. Polyethylene Glycol 3350, USP 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, USP, 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, USP 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, USP 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, USP over placebo was demonstrated.
