In- vitro undersøgelser viser, at ertapenem ikke hæmmer P- glycoprotein- medieret transport af digoxin eller vinblastin og, at ertapenem ikke er et substrat for P- glycoprotein- medieret transport.
In-vitro studies indicate that ertapenem does not inhibit P-glycoprotein-mediated transport of digoxin or vinblastine and that ertapenem is not a substrate for P-glycoprotein-mediated transport.
