Dronedarone: the effect of diet-induced obesity on its metabolism and experimental hyperlipidemia on its metabolism and tissue distribution in the rat
Bibliographic record
Abstract
Dronedarone biodistribution in hyperlipidemia and dronedarone metabolism in hyperlipidemia or obesity were assessed. Male Sprague-Dawley rats were given either normal standard chow with water or various high-fat or high-carbohydrate diets for 14 weeks. There was also a nonobese hyperlipidemic group given poloxamer 407 intraperitoneally. Liver and intestinal microsomes were prepared and the metabolic conversion of dronedarone to desbutyldronedarone was followed. A biodistribution study of dronedarone given orally was conducted in hyperlipidemic and control normolipidemic rats. The metabolism of dronedarone to desbutyldronedarone in control rats was consistent with substrate inhibition. However in the treatment groups, the formation of desbutyldronedarone did not follow substrate inhibition; hyperlipidemia and high-calorie diets created remarkable changes in dronedarone metabolic profiles and reduction in formation velocities. Tissue concentrations of dronedarone were much higher than in plasma. Furthermore, in hyperlipidemia, plasma and lung dronedarone concentrations were significantly higher compared to normolipidemia.

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.
