Bupropion SR als Unterstützung in der Raucherentwöhnung rückfälliger Raucher: Ergebnisse einer offenen multizentrischen Studie in Deutschland
Bibliographic record
Abstract
BACKGROUND: After initially successful smoking cessation the majority of patients relapse which stresses the addiction character of nicotine dependence. The patient and the physician, in therapeutic nihilism will not make another attempt for smoking cessation. In two randomised, double-blind, placebo-controlled trials in the US and Canada relapsed smokers, who had initially successfully quit smoking under Bupropion SR (Zyban), were again treated with Bupropion SR for smoking cessation. The encouraging results prompted us to perform a study in Germany under the conditions and temporal restraints of a routine medical practice. METHODS/PATIENTS: In this open multicentre study 321 patients of a total of 365 patients at 62 study sites were included. The patients represented a healthy population (= free of severe chronic disease) of smokers, who had relapsed after a smoking cessation attempt with Bupropion SR or nicotine replacement therapy and were currently smoking at least 20 cig./d for > 3 months. The treatment with Bupropion SR (300 mg/d) lasted 7 weeks, with initial run-in of 150 mg/d for the first three days; motivational counselling was provided during 4 clinical visits within the study duration of 26 weeks. RESULTS: 55.4 % of the patients were heavily or very heavily nicotine dependent as detected by the Fagerström Tolerance Questionnaire (score 6 - 11). The continuous abstinence rates for week 4 - 7 were 29.6 % (ITT) the point prevalence rates for week 26 were 30.5 % (ITT). Patients who showed a relapse had less daily cigarette consumption even after 26 weeks (10.3 cig./d versus 26.9 cig./d pretreatment). Nicotine craving reached a low plateau not earlier than week 6. Bupropion SR was well tolerated, only 9.7 % of the patients (ITT) withdrew from the study due to an adverse event. The most frequent adverse events were pain of the musculoskeletal system and insomnia. CONCLUSIONS: Bupropion SR was effective and well tolerated when given as an aid in smoking cessation in relapsed smokers.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
