Abstract

The complexity of the drug use process is managed in part by developing systematic nomenclature for drugs. This nomenclature is cataloged in a variety of drug information databases. Answers to simple questions about the whole population of brand and generic drug names, however, are not easily obtained. This paper provides a descriptive analysis of the drug name lexicon, with a primary (though not exclusive) emphasis on drugs marketed in the United States. Using the techniques of computational lexicography, one large database of trademark names (the US Patent and Trademark database) and one large database of nonproprietary names (the USP Dictionary of USAN and International Drug Names) were analyzed. Results describe a variety of distributional characteristics of drug names, including the number of characters per name, the number of syllables per name, and the number of words per name. Distributions of pairwise similarity and distance scores for a large sample of names are provided, as are lists of the 25 most common initial and terminal bigrams and trigrams. The information should be of interest to trademark attorneys, patient safety advocates, regulators, and students of drug nomenclature.
