Using bibliometric analyses of patent literature for predicting the clinical fates of developing drugs.

Certain bibliometric features of the early literatures of developing drugs can be used to predict their ultimate clinical fates. The chronological sequence of publications is expressed as a binary vector with 1 for a patent and 0 for a nonpatent. The decimal equivalents for standardized vector lengths provide scalar values for comparing one drug with another. In order to incorporate concordant patents, fuzzy subsets are employed, with the number of attempts required to achieve transitive closure being the values for comparison. The methods involved are described using minoxidil as an example.

Developing drug literatures. 1. Bibliometrics of baclofen and dantrolene sodium.

The literatures of two antispastic drugs, baclofen and dantrolene sodium, were studied bibliometrically for their first decade and were found to be generally similar. Baclofen had 93 papers and dantrolene sodium had 70. About a quarter of the baclofen papers were in a foreign language, whereas almost all dantrolene sodium papers were in English. Baclofen literature had a lower nonscholarly content, but the scholarly increase, 5%, was the same for both. Both drugs had an average of 12 references per paper. The literatures of both drugs had a similar degree of internal cohesiveness; almost half of their papers referred to other papers in the same drug collection. The first human paper for baclofen was the second published; for dantrolene sodium, it was the eleventh. The distribution of journals carrying papers on each of these drugs followed Bradford's law. Two authors per paper was the average for each drug. The productivity of authors approximated Lotka's law for both drugs. About two-thirds of the papers of both drugs had a drug-word in their titles. The literature of both drugs contained about 15% legendary papers, typical of clinical pharmacology. The most intense papers, 15 for baclofen and 11 for dantrolene sodium, were identified, using citation, bibliographic coupling, and co-citation frequencies. A generalization predicts what might be expected from the literature of future antispastic drugs.

Science-specialty literatures their legendary contemporary polarity, based on the transmission of information between generations.

Each of fifteen scientific specialty fields was represented by a journal and the percent of "legendary" papers (those with at least one reference twenty-five or more years old) was calculated for each field. Non-legendary papers were designated as "contemporary". A historical divergence was uncovered when the highly legendary field, physiology, was compared with the highly contemporary field, microbiology, both fields being moderately contemporary in 1922. The legendary contemporary field characteristics of a field are useful for estimating libraries' requirements for back holdings and for appraising literature searches.
