Evaluating the Effectiveness of LACTOFOS in Constipated Patients

Phase 3

• Conditions: Constipation
• Interventions: Dietary Supplement: Symbiotic Lactofos; Dietary Supplement: Maltodextrin

• Registration Number: NCT01286376
• Lead Sponsor: University of Sao Paulo

Brief Summary

Determine the effectiveness of symbiotic LACTOFOS containing FOS and probiotics against placebo in patients with a diagnosis of constipation, comparing the average number of weekly evacuations in 2 (two) groups for 30 days.

Detailed Description

A prospective, randomized, double blind, parallel group. Consist of a period of 30 days of treatment with placebo or with LACTOFOS.Will study 120 patients were female with a diagnosis of constipation according to Rome III criteria for at least 3 (three) months.

The experimental group (N = 60)will receive LACTOFOS 12g/day in two doses of 6 g. The control group (N = 60)will receive a placebo (maltodextrin) from 12g/day in two shots of 6 g.

Subsequently, the patients will be classified according to the study of AGACHAN, which determined a score based on the main complaints of patients. The symptoms that included evaluation for the total score were stool frequency, difficulty / straining, pain at defecation, feeling of incomplete evacuation, abdominal pain, time taken to initiate the evacuation, type of assistance for evacuation, failed attempts / day and duration of constipation. The intensity of each symptom varied within the range of 0 to 4, with the exception of the item type of assistance for evacuation, which ranged from 0 to 2.

Constipation is classified as mild when the total sum of values (scores) vary from 00 to 10, as moderate when the sum of the values obtained vary from 11 to 20 and severe when the final sum range from 21 to 30.
