Belsomra an effective option for delirium prevention, Finds study

The researchers in the present study sought to determine Belsomra (suvorexant, Merck) effects on delirium prevention in real-world settings. A total of 699 patients were analyzed, of whom 84 were suvorexant users and 615 were nonusers, who were admitted to the intensive care unit of a single academic hospital and stayed for at least 72 hours. An attending physician prescribed suvorexant for insomnia as part of everyday clinical practice.

Izuhara and colleagues conducted Cox proportional hazards regression analysis, adjusted for delirium-related covariates, on delirium-free survival for suvorexant users. Analyses included data of patients who were evaluated via the Confusion Assessment Method for the Intensive Care Unit, which was used to identify the presence of delirium at least twice per day throughout the ICU stay.

The following findings were observed-

7. delirium was noted in 214 patients, and its prevalence was significantly lower among suvorexant users vs. nonusers at 17.9% and 32.4%, respectively.
8. delirium among suvorexant users was associated with a significantly lower hazard ratio (HR = 0.472; 95% CI, 0.268-0.832) vs. non-users.
9. Trazodone also exhibited a preventive effect on delirium (HR = 0.345; 95% CI, 0.149-0.802).

Based on the outcomes, "The current study revealed that suvorexant prevents delirium in real-world settings," Izuhara and colleagues wrote. "A large, multicenter study is required to raise the quality of the intensive care system."
