Compartmental PK
A compartmental PK model is generally more complex than a noncompartmental PK model and allows for prediction of modeling profiles between compartments when experimental parameters are altered. Compartmental PK is appropriate for large and small molecules.
PK / PD Modeling
PBPK Modeling
PBPK modeling in being accepted more commonly by regulatory agencies as a way to inform clinical study designs and is also used as a way to compare therapeutic indications from multiple drug candidates. PBPK modeling does require a set of in vitro and in vivo data to verify the models.
QSP / SP Modeling
Quantiative and/or Systems Pharmacology (QSP/SP) modeling, a subdiscipline of pharmacokinetics, is an approach that integrates preclinical mechanistic evidence and physiological system models to investigate and predict drug response.
