Objectives: We carried out a bibliometric study on the
scientific publications in relation to atypical antipsychotic
drugs (AADs) in Spain.
Methods: We used the EMBASE and MEDLINE databases
and we applied some bibliometric indicators of paper
production and dispersion (Price’s law and Bradford’s law,
respectively). We also calculated the participation index of the
different countries and correlated the bibliometric data with
some social and health data (total per capita expenditure on
health and gross domestic expenditure on research and
development).
Results: We collected 656 original papers published
between 1988 and 2011. Our study results fulfilled Price’s law
with scientific production on AADs showing exponential
growth (correlation coefficient r = 0.9693, vs. r = 0.9177 after
linear adjustment). The most widely studied drugs were
risperidone (181 papers), olanzapine (143), clozapine (94),
and quetiapine (74). Division into Bradford zones yielded a
nucleus occupied by the European Psychiatry and European
Neuropsychopharmacology (70 articles). Totally 194
different journals were published, with 5 of the first 10 used
journals having an impact factor being greater than 4.
Conclusion: The publications on AADs in Spain have
undergone exponential growth over the studied period,
without evidence of reaching a saturation point.
