14. september 2012 oppdatert av: AstraZeneca
Multicentre, retrospective observational cohort study based on LHU administrative databases aimed to described the pharmacoutilization of antipsychotics in patients affected by schizophrenia and bipolar disorder, the resource consumption and medication adherence.
