Do antipsychotics decrease serotonin?

Serotonin receptors

Atypical antipsychotics block serotonin 5-HT2 receptors. When the ratio of 5-HT2 to D2 receptor blocking is greater than 1, atypical antipsychotic action such as therapeutic effects on negative symptoms and few EPS are noted.

What hormone is associated with schizophrenia?
