Clinical Details

Official title: Randomized Controlled Trial of Escitalopram Versus Placebo for Patients With Irritable Bowel Syndrome and Panic Disorder

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome:

Gastrointestinal Symptom Rating Scale (GSRS).

State Trait Anxiety Inventory (STAI).


Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.


Inclusion Criteria: 1. IBS will be diagnosed according to the Rome III criteria by a gastroenterologist. 2. Subtyping of IBS patients will be performed using the following classification according to the Rome III criteria: IBS with constipation (IBS-C), IBS with diarrhea (IBS-D), mixed IBS (IBS-M) or not subtyped IBS (IBS-U). 3. Based on the medical history and previous examination, no other causes for the abdominal complaints can be defined. 4. A panic disorder will be diagnosed based on DSM IV criteria by a psychiatrist. 5. Age above 18 years and under 70 years. 6. Given written informed consent. Exclusion Criteria: 1. Inability to stop medication that can influence gastrointestinal motility or perception (like loperamide, butylscopolamine, duspatalin, metoclopramide, domperidon, erytromycin), serotonin metabolism (like carbidopa, food supplementation), or epigenetics (like valproic acid), or containing perforated St. John's wort (Hypericum perforatum). In general this medication can be stopped without problems. However, this can increase symptoms. When the increase in symptoms will be to high, this medication will be restarted and the patient excluded form the study. 2. Administration of investigational drugs in the 180 days prior to the study. 3. Major abdominal surgery interfering with gastrointestinal function (uncomplicated appendectomy, cholecystectomy and hysterectomy allowed, and other surgery upon judgement of the principle investigator), epilepsy or (hypo)manic episodes. 4. Pregnancy and lactation. 5. Excessive alcohol consumption (> 20 alcoholic consumptions per week) or drug abuse. 6. Co-intervention or other treatment for IBS or anxiety, with the exception of initial co-intervention with benzodiazepines (alprazolam) contrasting side effects due to SSRI's during the first two weeks of dose elevation. 7. Known prolongation of QT-interval or long-QT-syndrome, other cardiac disease, or use of medication with known prolongation of QT-interval.
