Use Of Suvorexant And Antipsychotics In The Treatment Of Delirium After Infectious Diseases A Retrospective Study

Background Delirium is often treated on a subjective basis and per the discretion of the attending physician because of a lack of pharmacological evidence in the literature. To address this knowledge gap, we aimed to examine the efficacy of a hypnotic drug, suvorexant, as a therapeutic agent for the treatment of delirium. Methods Fifty-seven patients were targeted. Of the 57 patients, 39 were in the subolexant group, 17 in the antipsychotic group, and 1 was taking antidepressants. The Delirium Rating Scale-Revised 98 was used to evaluate the symptoms of delirium before and 3 and 7 days after drug administration. In addition, the medical history, occurrence of adverse effects, white blood cell count, and C-reactive protein level of participants were examined. Results Both drugs exhibited therapeutic effects on delirium, but suvorexant had a more pronounced effect. Furthermore, the suvorexant group exhibited decreased levels of C-reactive protein, suggesting an anti-inflammatory effect. Suvorexant seems to improve the symptoms of inflammation-related delirium without any serious adverse effects, suggesting that it can be explored as a safe treatment option for clinical use in future studies. Conclusions Our findings will be relevant for physicians interested in learning about new pharmacological treatment options and researchers interested in validating our results.
