RESUMO
Objective: We carried out a bibliometric study on the scientific papers related to second generation anti-psychotic drugs (SGAs) in Malaysia. Methods: With the SCOPUS database, we selected those documents made in Malaysia whose title included descriptors related to SGAs. We applied bibliometric indicators of production and dispersion, as Price’s law and Bradford’s law, respectively. We also calculated the participation index of the different countries. The bibliometric data were also been correlated with some social and health data from Malaysia (total per capita expenditure on health and gross domestic expenditure on R&D). Results: We found 105 original documents published between 2004 and 2016. Our results fulfilled Price’s law, with scientific production on SGAs showing exponential growth (r = 0.401, vs. r = 0.260 after linear adjustment). The drugs most studied are olanzapine (9 documents), clozapine (7), and risperidone (7). Division into Bradford zones yields a nucleus occupied by the Medical Journal of Malaysia, Singapore Medical Journal, Australian and New Zealand Journal of Psychiatry, and Pharmacogenomics. Totally, 63 different journals were used, but only one in the top four journals had an impact factor being greater than 3. Conclusion: The publications on SGAs in Malaysia have undergone exponential growth, without evidence a saturation point.
RESUMO
Objective: A bibliometric study of peer-reviewed scientific publications on atypical antipsychotic drugs (AADs) from Italy is herein presented. Methods: We selected the documents from Scopus database. We applied several bibliometric indicators of production and dispersion, including Price's Law about the increase of scientific literature, and Bradford's Law. We also calculated the participation index across different countries. The bibliometric data have also been correlated with some social and health data sourcing in Italy, such as total per capita expenditure on health and gross domestic expenditure. Results: A total of 2949 original documents were published within the period 1972-2015. Our results state fulfilment of Price's Law, with scientific production showing exponential growth (r=0.901, as against an r=0.838 after linear adjustment). The drugs most widely studied were clozapine (257 documents), risperidone (179), and olanzapine (172). Stratification into Bradford zones yielded a nucleus represented by the Journal of Clinical Psychopharmacology and Rivista di Psichiatria (58 articles, each one). A total of 1091 different journals were evaluated. Conclusions: The publications on AADs in Italy have undergone exponential growth over the studied period, which is in line with the progressively burgeoning on novel AAD releases. No evidence of saturation point was observed.
