Mechanism of action

The mechanism of action of Seroquel (quetiapine) is not fully understood, but it is thought to involve antagonism of various neurotransmitter receptors in the brain. Specifically, Seroquel acts as an antagonist at dopamine D2 and serotonin 5-HT2A receptors.

Dopamine is a neurotransmitter that plays a role in regulating mood, motivation, and pleasure. By blocking dopamine receptors, Seroquel helps to regulate the activity of this neurotransmitter in order to reduce symptoms of certain mental disorders, such as schizophrenia and bipolar disorder.

Similarly, Seroquel’s antagonism at serotonin 5-HT2A receptors helps to balance serotonin levels in the brain. Serotonin is another neurotransmitter involved in mood regulation, and abnormal serotonin levels have been implicated in various mental disorders.

In addition to its effects on dopamine and serotonin receptors, Seroquel also acts as an antagonist at adrenergic alpha-1 receptors and histamine H1 receptors. These actions contribute to the sedative and antihistamine effects of the medication.

Overall, the precise mechanism of action of Seroquel is complex and multi-modal, involving interactions with several different neurotransmitters. By modulating the activity of these neurotransmitters, Seroquel helps to restore a more balanced brain chemistry and alleviate symptoms associated with schizophrenia and bipolar disorder.
