Link Between Antipsychotic Drugs and COVID-19 Protection

"The number of Covid-19 patients is lower than expected among this group of people and in cases where a proven infection does occur, the evolution is benign and does not reach a life-threatening clinical situation. These data as a whole seem to point to the protective effect of the medication," he adds.

Complementary to this study, the same research group has observed that many of the genes whose expression is altered by Covid-19 are significantly down-regulated by antipsychotic drugs, which are commonly used to treat diseases with psychotic symptoms.

This finding was achieved by investigating the gene expression profile (indicator of activated biological processes) of Covid-19 patients (Wuhan cohort) and patients being treated with antipsychotic drugs (specifically, aripiprazole) from the cohort of the Early Phases of Psychosis Intervention Programme (PAFIP) initiated 20 years ago at the Marqués de Valdecilla University Hospital in Cantabria by Benedicto Crespo-Facorro, professor at the University of Seville and current director of the Mental Health Unit at the Virgen del Rocío University Hospital.

"In a striking way we have shown how antipsychotics reduce the activation of genes involved in many of the inflammatory and immunological pathways associated with the severity of Covid-19 infection," says the lead author of the second paper, Professor Crespo-Facorro.

Furthermore, he stresses that "although this finding requires replication, the discovery could be very significant because the treatment of Covid-19 with drugs originally indicated for unrelated clinical situations, that is to say drug repositioning, has been shown to be an interesting source of effective treatments for Covid-19 patients".
