G20 Global Pharma Summit Series-China

Toxicology is the study of the mechanisms by which pharmaceuticals and chemicals in the environment generate undesired effects, whereas Pharmacology is the scientific field that investigates the mechanisms by which drugs modify biological systems in an attempt to promote health and alleviate sickness. These fields combine to address the molecular foundation of drug action, drug activities on cells, organs, and organisms, genetic variations in drug action, and drug development.
