How does quetiapine work?
Quetiapine is an atypical antipsychotic medication. It works by affecting the activity of neurotransmitters in the brain, primarily dopamine and serotonin. By balancing these chemicals, it helps to manage symptoms associated with conditions like schizophrenia, bipolar disorder, and major depressive disorder. It is thought to block certain receptors in the brain, which helps to regulate mood and thinking.
