Imodium Syrup Versus Imodium Tablets for Faecal Incontinence

November 17, 2014 updated by: University Hospital Southampton NHS Foundation Trust

Single Blinded Randomised Cross-over Study of Imodium Tablets Versus Imodium Syrup for the Treatment of Faecal Incontinence

Faecal incontinence (FI) is a debilitating and often neglected problem. It can be defined as the loss of voluntary control of liquid or solid stool.It is estimated that 2-3% of western adults suffer from FI with prevalence increasing with age, further to this up to 50% of nursing home residents suffer too with it more common in females. Aetiology is often multi-factoral, where obstetric anal sphincter injury is most common is females and iatrogenic anal sphincter injury is most common in males.

Loperamide (imodium) is a constipating agent used as first choice pharmacological agent due to its high efficacy. Trials have suggested it thickens stool consistency and may raise resting anal sphincter pressure, associated with improved clinical function with a reduction in bowel frequency and urgency, a reduction in incontinence and less need for pads.

Loperamide is well tolerated but has been known to cause side effects of abdominal pain and distension, nausea and vomiting and constipation.

Imodium can be taken in two ways; as syrup (1mg/5mls) or tablets (2mg). There have been no comparative studies. Side effects are mainly seen with the tablet form and so it is hypothesized that the syrup form is better tolerated because it is more accurately titrated to effect.

This is a NHS funded single blinded, randomised, cross-over study to assess the clinical effects of Imodium, in tablet and syrup form, on patients presenting with faecal incontinence. Each subject will act as their own control. Patients will be recruited through out-patient visits for their FI, where they will be made aware of the trial. During the trial they will be asked to fill out FI scoring questionnaires and quality of life scores. Also they will undertake two assessments of anal physiology testing squeeze pressures, sensation and compliance at baseline and at the end after three months.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Aged 18 - 75
  • Severe faecal incontinence defined as greater than one episode per week of involuntary loss of either solid or liquid stool as demonstrated by means of a baseline bowel habit and a Vaizey score of greater than 4.
  • Competent and willing to fill in questionnaires and attend follow up clinics through out the study period.

Exclusion Criteria:

  • Alternating bowel habit, associated with symptoms of constipation. Use of other regular or as required medications that may affect bowel function. (e.g. codeine phosphate).
  • Patients with complete or partial spinal cord injuries including cauda equina syndrome.
  • Active inflammatory bowel disease.
  • Pregnancy
  • Stoma in situ
  • Psychiatric and physiological inability to comply with study protocol.
  • Non english speakers (student project funding cannot cover interpreter and other costs)

(application of criteria at the discretion of the investigating doctor at initial consultation)
