Drug toxicity is the study of harmful effects that occur when a medication is taken in doses that exceed the therapeutic range. This field of research aims to understand the mechanisms of drug toxicity, the factors that influence an individual's susceptibility to adverse effects, and strategies for preventing and managing drug-related harm. Researchers in this area investigate the biochemical, physiological, and genetic factors that contribute to drug toxicity, as well as the impact of drug-drug interactions and drug metabolism on the risk of adverse reactions. By studying drug toxicity, researchers can improve drug safety, develop more effective treatments, and enhance patient care.
