Paroxetine-CR (Paxil-CR) in the Treatment of Patients With Fibromyalgia Syndrome: A Randomized, Double Blind, Parallel Group, Flexible Dose, Placebo Controlled Trial.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Objective: Although there is a high comorbidity of depressive and/or anxiety disorders with fibromyalgia, information on the clinical implications of this comorbidity is limited. We investigated whether a history of depressive and/or anxiety disorders was associated with response to treatment in a double blind, randomized, placebo controlled trial of paroxetine controlled release (CR) in fibromyalgia. Method: One hundred and sixteen fibromyalgia subjects were randomized to receive paroxetine CR (dose 12.5-62.5 mg/day) or placebo for 12 weeks. The Mini International Neuropsychiatric Interview (M.I.N.I-plus) was used to ascertain current or past diagnoses of depressive and anxiety disorders. Patients with current depressive or anxiety disorders were excluded, but those with past diagnoses were enrolled in the trial. Subjective depression and anxiety were assessed using the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI); subjects were excluded if they scored greater than 23 on the BDI. Health Status was determined using the 36-Item Short Form Health Survey (SF-36), the Sheehan Disability Scale (SDS), the Perceived Stress Scale (PSS) and the Pittsburgh Sleep Quality Index (PSQI). The primary outcome was treatment response defined as ≥ 25% reduction in the Fibromyalgia Impact Questionnaire (FIQ) score. Secondary outcomes included changes in scores on the Clinical Global Impression-Severity and Improvement (CGI-S and CGI-I respectively), the Visual Analogue Scale for Pain (VAS) scores and number of tender points.
