The Transfer of Domperidone into Human Milk Remains Low at High Doses
Bibliographic record
Abstract
Domperidone is a dopamine-2 (D2) receptor antagonist that stimulates the release of stored prolactin in the anterior pituitary. It is prescribed off-label in Canada and Australia to promote lactation in prolactin-deficient women. The case of a 43-year-old woman taking a high daily dose of domperidone (160 mg) is described from the InfantRisk Center Human Milk Biorepository. Milk samples were analyzed using a high-performance liquid chromatography-mass spectrometry method, detecting an average domperidone concentration of 7.0 ng/mL (range 6.2 to 8.4 ng/mL). Even at high doses, the transfer of domperidone into breast milk was negligible with a relative infant dose (RID) of 0.05%. The RID estimates the infant's potential exposure to a drug via lactation as a percentage of the weight-adjusted maternal dose. The standard threshold for reasonable infant exposure is an RID of 10%.

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.
