Clinical pharmacology is a branch of pharmacology that focuses on the study of drugs in humans. It involves the study of how drugs interact with the body, including their absorption, distribution, metabolism, and excretion. Clinical pharmacologists also study how drugs affect different populations, such as children, elderly individuals, and individuals with various health conditions. This research area aims to improve the safety and efficacy of drug therapies for patients through the use of evidence-based practices and personalized medicine approaches. Clinical pharmacology plays a crucial role in drug development, regulatory approval, and clinical practice.
