Medication therapy management (MTM) includes various clinical pharmacy services that greatly influence society and economy. Despite extensive research in recent years, there is currently a lack of bibliometric analysis on this subject. Articles and reviews on MTM published from 2003 to 2023 were identified and selected from the Web of Science Core Collection. CiteSpace, VoSviewer, Bibliometrix, and Microsoft Excel were used to conduct bibliometric analysis and knowledge mapping. The bibliometric analysis encompassed 3255 publications on MTM. The United States and the United Kingdom emerged as the most influential countries in this particular domain, whereas Brigham and Women’s Hospital and Harvard Medical School were the most active institutions. Elizabeth Manias published the largest number of papers, whereas Jeffrey L. Schnipper published the largest number of co-citations. The American Pharmacists Association has been identified as the most prolific journal in this field. Optimizing medication and ensuring drug safety in elderly patients are current research frontiers. Topics such as “polypharmacy,” “dementia,” “oncology,” and “anticholinergic burden” were identified as potential research priorities in the future. This study is the first to utilize bibliometric analysis to uncover the global status, research hotspots, and future development trends of MTM for scholars, thereby providing valuable guidance for future research endeavors.
