ADME

Preclinical ADME studies are designed to investigate the absorption, distribution, metabolism and excretion of novel pharmaceuticals to support lead candidate selection, preclinical testing and clinical development programs. Charles River offers custom-designed ADME studies in multiple species of laboratory animals using cold or radiolabelled test materials administered by a variety of routes.

Our experienced scientists routinely conduct mass balance and tissue distribution studies to determine tissue half-life, clearance rates, and potential sites of toxicity after systemic exposure. These studies are all managed using the DEBRA® Windows LIMS System to provide full electronic data collection and evaluation. We can arrange and manage custom radiosynthesis on your behalf and are able to undertake re-purification and radiodilution of radiolabelled test materials if required.
