Pharmacokinetics is the study of how drugs are absorbed, distributed, metabolized, and excreted in the body. This field focuses on understanding how drugs move through the body, how they are processed by various organs such as the liver and kidneys, and how they are eventually eliminated from the body. Pharmacokinetics is important for determining the appropriate dosage of a drug, predicting its effects, and assessing potential drug interactions. By studying pharmacokinetics, researchers can better understand how drugs behave in the body and optimize their therapeutic use.
