A Randomized, Parallel Group Comparison of Loperamide/Simeticone Caplet, Loperamide/Simeticone Chewable Tablet (IMODIUM® PLUS) and a Probiotic (Saccharomyces Boulardii) in the Treatment of Acute Diarrhea in Adults

A comparison of three medications to treat diarrhea in adults.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This single (investigator) blind, randomized, 3-arm, parallel-group study design was selected to show non-inferiority of loperamide/simeticone caplets compared to chewable tablets in a heterogeneous subject population aiming at validity of results and reducing bias. The study will also compare the loperamide/simeticone combinations versus a probiotic (Saccharomyces boulardii) in the treatment of acute diarrhea in adults. Probiotics have been used for acute infectious diarrhea to reduce the duration and severity of the illness.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
