Summary of key MiraLAX® clinical studies
and analyses
MiraLAX® is supported by 19 years of safe and effective use
- Evaluated the safety and effectiveness of MiraLAX® in 151 people with constipation
- Patients were given either MiraLAX® or a placebo, and kept track of any changes in how often they had bowel movements as well as associated subjective symptoms.
- After 2 weeks, patients who took MiraLAX® had significantly (P<0.001) more bowel movements as well as significantly less severe cramping and gas (P<0.001).
- Evaluated the safety and effectiveness of MiraLAX® laxative in people with constipation
- Twenty-three patients with constipation were given the normal daily dose (17 g) of MiraLAX® or a placebo, after which they recorded each bowel movement and associated symptoms in a diary and watched for any changes in how often they had bowel movements.
- After 14 days, patients given MiraLAX® had significantly more bowel movements than those on placebo (7.0 vs 3.6, respectively, in week 2; P<0.001), and they had no serious side effects.
- Randomized clinical trials conducted between 1966 and 2003 were identified to evaluate the safety and efficacy of different laxatives.
- Polyethylene glycol received Level 1, Grade A ratings.
- Level 1: Consistent results from well-designed, well-conducted studies
- Grade A ratings for efficacy and safety: Good evidence in support of the use of a modality in the treatment of constipation
- Patients taking constipation-inducing medications (≥3% incidence of constipation) were randomized to treatment with 17 g PEG 3350 (n=50) daily or placebo (n=50) for 28 days.
- The primary efficacy variable of treatment success was based on the presence of no more than one of the following in 25% of bowel movements or <3 bowel movements per week over the last 7 days of treatment:
- Straining
- Lumpy/hard stool
- Incomplete evacuation
- Anorectal obstruction
- Manual maneuvers
- PEG 3350 was significantly superior vs placebo in the primary efficacy endpoint of treatment success: 78.3% vs 39.1% (P<0.001), respectively.
- Statistically significant difference in favor of PEG 3350 over placebo were observed:
- After first week of treatment:
- Total number of bowel movements per week
- Number of complete bowel movements
- Number of satisfactory bowel movements
- For all treatment weeks:
- Straining
- Stool consistency
- There were no statistically significant treatment-emergent adverse events, including GI complaints.
- After first week of treatment:
- Patients with modified Rome functional constipation criteria of <3 satisfactory bowel movements per week, with straining in >25% of defecations, hard or lumpy stools in >25% of defecations, or sensation of incomplete evacuation in >25% of defecations for a 3-month period were randomized to treatment with 17 g PEG 3350 (n=204) daily or placebo (n=100).
- The primary efficacy variable of treatment success was defined as no rescue laxative use, ≥3 satisfactory stools per week, and ≤1 remaining symptom of the modified Rome criteria defined above.
- Significantly more PEG 3350 patients (52%) were successfully treated compared to placebo (11%, P<0.001).
- PEG 3350 was significantly superior (P<0.001) to placebo for:
- Number of bowel movements per week
- Satisfactory bowel movements per week
- Complete spontaneous bowel movements
- While the individual GI adverse events did not differ significantly than with placebo, when combined these GI events (diarrhea, flatulence, loose stools, and nausea) occurred significantly more often with PEG than with placebo (40% vs 25%, P<0.015).
- No clinically significant changes in laboratory test results were reported.
- A 2011 Cochrane review identified and reviewed all randomized controlled trials comparing the use of lactulose and polyethylene glycol in the management of fecal impaction and chronic constipation (Rome III criteria) in adults and children. Both monotherapy and crossover studies were reviewed.
- The findings of this meta-analysis indicate that polyethylene glycol is better than lactulose in outcomes of stool frequency per week, form of stool, relief of abdominal pain, and the need for additional products.
