Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Hypotheses: 1. Primary null hypothesis: The rate of clinical response, assessed as patient-reported global symptom rating and "adequate relief of IBS symptoms," does not differ between non-depressed IBS patients treated with the SSRI citalopram and patients treated with placebo. 2. Secondary null hypotheses: 1. Changes in disease-related quality of life, assessed with the IBS-QOL instrument, do not differ between patients treated with the SSRI citalopram and patients treated with placebo. 2. Changes in rectosigmoid visceral sensitivity, assessed by barostat balloon distention, do not differ between patients treated with the SSRI citalopram and patients treated with placebo.
