Abstract

fetched live from OpenAlex

Abuse of psychotropic medications causes significant morbidity and mortality in North America. Results from traditional assessments of abuse liability may not be generalizable to individuals with mental illnesses or for drugs with ill-defined mechanisms of action. Pregabalin is an anticonvulsant medication used off-label to manage benzodiazepine withdrawal symptoms. Simultaneously, reports of its abuse have emerged. Two novel approaches were used to assess pregabalin’s abuse potential. On the macro-level, adverse drug reaction data from Canada’s national database were evaluated in Study 1. Results indicated that cases found in this spontaneous reporting system can provide early indicators of prescription drug abuse. On the micro-level, Study 2 aimed to assess the acute effects of pregabalin in inpatients withdrawing from benzodiazepines and produced valuable information concerning study design, which can be used to inform future research. Overall, these novel macro-and micro-level approaches in assessing abuse potential of psychotropic drugs are complementary and synergistic with traditional methods.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
