Add-on Treatment of Quetiapine for Fibromyalgia
Bibliographic record
Abstract
Recently, second-generation antipsychotic drugs have attracted interest in the treatment of chronic pain, including fibromyalgia (FM). Preliminary uncontrolled studies have shown that quetiapine treatment may be helpful for FM patients. In this trial, we sought to examine-for the first time-the efficacy and tolerability of quetiapine as a treatment for FM and its associated psychiatric symptoms. This was a 12-week double-blind, randomized, placebo-controlled trial of quetiapine XR as an add-on treatment for FM syndrome. Fifty-one female FM patients were randomized, and a flexible dosage of 50 to 300 mg/d was used. The primary outcome was the change from baseline to end point in the Fibromyalgia Impact Questionnaire total score. Secondary outcomes included mood symptoms, sleep disturbances, and tender points. Using a low dose (mean = 132.2 mg) of quetiapine, we observed significant benefits of drug treatment on sleep, uncertain effects on FM and mood symptoms, but no effects on pain, in a small group of polymedicated FM patients. Quetiapine was generally well tolerated.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
