Antibiotic use is a research area focused on the study of the administration and effects of antibiotics, which are medications used to treat bacterial infections. This research area includes the study of appropriate antibiotic prescribing practices, the development of antibiotic resistance, the impact of antibiotic use on microbial communities, and strategies to optimize antibiotic therapy to improve patient outcomes and minimize the development of resistance. Additionally, researchers may also explore the economic, social, and ethical implications of antibiotic use in healthcare settings.
