Clinical Pharmacology of Dronedarone: Implications for the Therapy of Atrial Fibrillation
Bibliographic record
Abstract
Dronedarone, a recently approved antiarrhythmic agent, is a chemical analog of amiodarone. It has an approximately 15% bioavailability, with plasma concentrations markedly increasing after a high-fat meal; it is recommended to be taken with food. The primary metabolic clearance pathway for dronedarone is via the hepatic enzyme system (primarily cytochrome P450 3A4 [CYP3A4]); the half-life of dronedarone is 27 to 31 hours. Strong CYP3A4 inhibitors, such as ketoconazole, are associated with a marked increase in dronedarone maximum concentration and are thus contraindicated; inducers of CYP3A4 will conversely decrease dronedarone exposure. Dronedarone is a substrate for P-glycoprotein (P-gp) and will lead to an increase in concentration of P-gp substrates such as digoxin. Dronedarone will cause a small increase in creatinine concentrations, without a change in glomerular filtration rate (GFR). Gender, renal dysfunction, weight, and age have little effect on the pharmacokinetics of dronedarone, and dose adjustment for these variables is not required.

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.
