Pharmacology is the branch of medicine that deals with the study of drugs and their effects on living organisms. It involves the study of how drugs interact with biological systems, and how they are absorbed, distributed, metabolized, and excreted by the body. Pharmacologists work to develop and test new drugs, as well as to improve the safety and efficacy of existing medications. They collaborate with other medical professionals to determine the best treatment options for patients, based on their unique medical histories and conditions. Understanding pharmacology is crucial for medical professionals, researchers, and individuals seeking to make informed decisions about their own health and well-being.
