Risk of extrapyramidal side effects in the newborn after single dose maternal metoclopramide administration prior to cesarean section: an analysis via physiology-based pharmacokinetic and pharmacodynamic modeling

Background Metoclopramide is prescribed during pregnancy to treat nausea and vomiting. Despite its widespread application, there is potential for peripartum maternal metoclopramide dosing to induce extrapyramidal symptoms (EPS) in the newborn due to residual pediatric drug levels at birth. Here, a physiology-based pharmacokinetic model, including pregnancy-related changes and placental transfer values, was established and verified for metoclopramide. Human placenta cotyledon perfusion experiments were conducted to estimate placental transfer of metoclopramide. Transfer parameters were incorpor
