Quetiapine vs. Haloperidol: A New Look at Managing ICU Delirium

Delirium remains a significant challenge in intensive care units, affecting nearly 32% of all critically ill patients and surging as high as 91% for those on mechanical ventilation. While haloperidol has traditionally served as the first-line treatment, its association with distressing extrapyramidal side effects and severe sedation has led researchers to explore safer alternatives. A recent randomized controlled trial published in Neurocritical Care investigated whether quetiapine, an atypical antipsychotic with a more favorable side-effect profile, could match the efficacy of haloperidol specifically for the hyperactive form of delirium.
The study, which followed 100 adult patients, found that quetiapine and haloperidol were remarkably similar in their primary clinical impact. Both drugs achieved an overall response rate of 92%, defined by a significant reduction in delirium severity scores. Furthermore, there were no statistically significant differences between the two groups regarding mortality rates in the ICU or the hospital, the need for mechanical ventilation, or the total length of hospital stay. These findings suggest that for symptom management, quetiapine is just as effective as the traditional standard of care.
However, the quetiapine group showed distinct advantages in secondary outcomes that could influence patient recovery environments. Patients receiving quetiapine experienced a statistically significant reduction in their mean ICU stay—10.1 days compared to 11.7 days for the haloperidol group. Additionally, quetiapine was associated with a notable increase in nightly sleeping hours by the third and seventh days of treatment. While the study’s small sample size may limit broad generalizations, these results indicate that quetiapine offers a promising, potentially more efficient alternative for managing hyperactive delirium in the ICU.
