Abstract

fetched live from OpenAlex

OBJECTIVE: To determine whether the hypnosedative drug zopiclone could be an agent for abuse. SOURCES OF INFORMATION: Using MEDLINE and PubMed, English-language medical literature was systematically reviewed for reports of direct drug abuse and addiction. A review was also conducted for clinical trials or patient series that discussed issues of addiction or rebound effects. MAIN MESSAGE: Evidence of drug abuse and dependency was found in case reports and small patient series. Dependency symptoms of severe rebound, severe anxiety, tremor, palpitations, tachycardia, and seizures were observed in some patients after withdrawal. Abuse occurred more commonly among patients with previous drug abuse or psychiatric illnesses. Many clinical trials have found evidence of rebound insomnia after recommended dosages were stopped, albeit for a minority of patients. Comparative studies of zopiclone and benzodiazepines or other "Z" drugs are conflicting. CONCLUSION: Zopiclone has the potential for being an agent of abuse and addiction. While many have suggested that the addictive potential for this and other "Z" drugs is less than for most benzodiazepines, caution should be taken when prescribing this agent for insomnia. Ideally, prescriptions should be given for a short period of time and within the recommended dosage guidelines.

Teacher imitation

Not 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.
