This is an open label, randomized, add-on, 8 weeks multicentre study to evaluate the efficacy and safety of paroxetine Controlled Release (CR) in patients with Major Depressive Disorder (MDD) comorbid Irritable Bowel Syndrome (IBS).

Subjects will be patients who are referred to the outpatient or inpatient clinic of gastroenterology departments of province level general hospitals in China. All subjects present with irritable bowel syndrome according to ROME III, and also are diagnosed with MDD by Mini-International Neuropsychiatric Interview (MINI). All subjects will provide written informed consent prior to participating in the study. Subjects will be assessed for eligibility at a screening visit, with eligible patients returning for a assessment within 1 week, at which time they will randomly enter into paroxetine CR (12.5mg/d, flexible dose: 12.5-50mg/d) plus IBS regular treatment or IBS regular treatment only. Subjects will be evaluated at weeks 2 (Day 14), 4 (Day 28), 6 (Day 42) and 8 (Day 56), for a total of 5 study treatment visits.

Arms Assigned Interventions
Experimental: Paroxetine CR group
Paroxetine CR plus IBS regular treatment group
Drug: Paroxetine CR
Paroxetine CR will be provided by GlaxoSmithKline (GSK) and be available as 12.5 mg over-encapsulated tablets with the research use only label outside the package. Paroxetine CR should be administered as a single daily dose, with or without food. The recommended initial dose is 25 mg/day. Patients were dosed in a range of 25 mg to 62.5 mg/day in the clinical trials demonstrating the effectiveness of paroxetine CR in the treatment of major depressive disorder. As with all drugs effective in the treatment of major depressive disorder, the full effect may be delayed. Some patients not responding to a 25-mg dose may benefit from dose increases, in 12.5 mg/day increments, up to a maximum of 62.5 mg/day. Dose changes should occur at intervals of at least 1 week.

  2. History of alcohol / drug dependence and schizophrenia; history of serious mental illness;
  3. Major neurological deficits that interfere with the patient's ability to understand the study procedures and provide a written informed consent;
  4. Patients were also excluded if their current episode of depression had failed to respond to two or more adequate trials of antidepressants, benzodiazepines, or other anxiolytics at a clinically appropriate dose for a minimum of 4 weeks;
  5. Suicide ideation;
  6. Use monoamine oxidase inhibitors (MAOIs), benzodiazepines or other antidepressants within at least 14 days before study begin;
  7. Other medical and psychological conditions prevent patients from participating in the study or signing informed consent;

  12. Recent gastrointestinal surgery (within 6 months).
  13. Has received electroconvulsive therapy (ECT) or psychotherapy in the 3 months prior to screening.
  14. Presents with clinically significant abnormalities in haematology, clinical chemistry, electrocardiogram (ECG) or physical examination at screening which have not resolved prior to the baseline visit or has clinically significant conditions, which in the opinion of the investigator, will render the patient unsuitable for the study and pose a safety concern or interfere with the accurate safety and efficacy assessments (e.g., severe cardiovascular disease, hepatic or renal failure etc).
