Breast milk concentrations of amiodarone, desethylamiodarone, and bisoprolol following short‐term drug exposure: Two case reports
Bibliographic record
Abstract
Two cases of mothers given postpartum short-term administration of amiodarone, with and without bisoprolol, are described along with determinations of amiodarone and (±)-bisoprolol in the breast milk. In one mother given a cumulative total of amiodarone of 8 g over 1 week, concentrations 11 days after the drug had been stopped were initially deemed sufficient to pose a risk to an infant. Over the next 5 days the concentrations steadily dropped with amiodarone and desethylamiodarone concentrations being found to be at a level comprising minimal risk to the infant. Bisoprolol was not found in the expressed breast milk. In the second case the mother was given a single 150 mg dose of amiodarone and breast milk concentrations were measured on postpartum days 4 and 5. Breast milk amiodarone concentrations were very low and of little concern clinically had the mother breast fed her baby. The risk to the baby of ingesting breast milk after amiodarone administration postpartum depends on the duration of amiodarone exposure, with a single dose posing minimal risk. Bisoprolol does not appear to accumulate to any great extent in breast milk.

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.
