Quantitative Tissue Distribution Studies

Quantitative tissue distribution studies can analyze the distribution of drugs in different tissues, to determine the metabolism and excretion pathways of rare disease drugs in the body, and provide an important reference for clinical research of rare diseases. Our company has extensive expertise in pharmacokinetics, we can provide efficient methods to accelerate your tissue distribution studies.

Introduction to Quantitative Tissue Distribution

Quantitative tissue distribution studies are an important part of pharmacokinetic analysis. There are several parameters involved in the drug tissue distribution process, such as blood perfusion, plasma protein and tissue binding, pH value, blood flow rate, partition characteristics, etc. These parameters affect the delivery, retention, and elimination of drugs in biological tissues.

Quantitative tissue distribution studies can provide information on the distribution and accumulation of compounds and their metabolites, identifying potential toxicity. The use of radiolabeled compounds to study tissue distribution is the most efficient method to quantitatively assess the localization of the parent molecule or its metabolites. Quantitative whole-body autoradiography (QWBA) and microautoradiography (MARG) techniques rely on the use of radiolabeled drugs and are commonly used to examine drug tissue distribution.

Quantitative tissue distribution studies can provide important information for the safety and efficacy evaluation of rare disease candidate drugs and are an integral part of the preclinical research of rare disease drugs.
