A Physiologically Based Pharmacokinetic Model for the Prediction of Plasma and Bone Tissue Exposure after Prophylactic Administration of Ampicillin/Sulbactam in Patients with Osteonecrosis of the Jaw

In this work, we present the first PBPK model that simultaneously predicts AMP and SBC in plasma and various tissues. In addition to observed plasma data, the model was also developed and verified with experimentally measured data from the above-mentioned tissues. This allowed a significant limitation of previous PBPK models to be overcome. The effectiveness of established prophylaxis regimes is demonstrated through our model, whereby it must be assumed, owing to measured data for bone tissue, that some individuals do not reach the target values for adequate prophylaxis.
