What makes seroquel so sedating?

Seroquel, or quetiapine, is a medication primarily used to treat schizophrenia and Bipolar disorder. Its sedative effects are largely due to its antagonistic action on histamine H1 receptors, which promotes drowsiness. Additionally, its effects on serotonin and dopamine receptors contribute to its calming properties. This combination of receptor interactions results in significant sedation, making it effective for managing agitation and sleep disturbances in patients.
