Introduction A bibliometric study was carried out to ascertain the volume and impact of scientific literature
published on second-generation antipsychotic drugs (SGAs) in Singapore from 1997 to 2011.
Method s A search of the EMBASE and MEDLINE databases was performed to identify articles originating from
Singapore that included the descriptors ‘atypic* antipsychotic*’, ‘second-generation antipsychotic*’, ‘clozapine’,
‘risperidone’, ‘olanzapine’, ‘ziprasidone’, ‘quetiapine’, ‘sertindole’, ‘aripiprazole’, ‘paliperidone’, ‘amisulpride’, ‘zotepine’,
‘asenapine’, ‘iloperidone’, ‘lurasidone’, ‘perospirone’ and ‘blonanserin’ in the article titles. Certain bibliometric indicators
of production and dispersion (e.g. Price’s Law on the increase of scientific literature, and Bradford’s Law) were
applied, and the participation index of various countries was calculated. The bibliometric data was also correlated
with some social and health data from Singapore, such as the total per capita expenditure on health and gross
domestic expenditure on research and development.
Results From 1997 to 2011, a total of 51 articles on SGAs in Singapore were published. Our results suggested
non-fulfilment of Price’s Law (r = 0.0648 after exponential adjustment vs. r = 0.2140 after linear adjustment).
The most widely studied drugs were clozapine (21 articles), risperidone (16 articles) and olanzapine (8 articles).
Division into Bradford zones yielded a nucleus occupied by the Journal of Clinical Psychopharmacology
(6 articles) and the Singapore Medical Journal (4 articles). The analysed material was published in a total of 30
journals, with the majority from six journals. Four of these six journals have an impact factor greater than 2.
Conclusion Publications on SGAs in Singapore are still too few to confirm an exponential growth of scientific
literature.
