Study description

Hydroxychloroquine (HCQ) and chloroquine (CQ) are nationally authorised 4-aminoquinoline antimalarial agents originally developed as less toxic alternatives to quinine. Both have risen to prominence in the earlier months of 2020 as potential treatments in the current COVID-19 pandemic. In May 2020, the Spanish regulatory Agency (AEMPS) warned about the occurrence of neuropsychiatric reactions associated with intake of HCQ and CQ in patients being treated for COVID-19. This new information let to initiation of a signal procedure at the European Union’s Pharmacovigilance Risk Assessment Committee (PRAC) and led to further review of data pertaining to the association of neuropsychiatric reactions with chloroquine/hydroxychloroquine. Analyses of healthcare records held at the EMA has supported further analyses of data relating to this signal. This study has considered data recorded in the electronic electronic health records database: IMS ® Disease Analyzer Germany (IMS‐Germany). It looks at the risk of “Psychosis and psychotic disorders” and “Depression and suicide/self-injury” following exposure to Hydroxychloroquine and Chloroquine.
