Drug Design, Development and Therapy 7: 93-98.1177-8881http://nrs.harvard.edu/urn-3:HUL.InstRepos:10589777The Top Journal Selectivity Index (TJSI) is a scientometric index reflecting the potential importance of a new drug. It represents the ratio of the number of all types of articles on a particular drug in the top 20 journals relative to the number of articles in all (>5,000) biomedical journals covered by Medline over the 5 years since the drug’s introduction. The TJSI can be an indicator of a drug’s potential for sustained use: a higher score increases the probability of continuing success.en-USbibliometrics‘me-too’ drugspharmaceutical marketscientometricsJournal Article2013-04-2610.2147/DDDT.S37324
