the preferential docking and receptor binding with D2 and D3 (partial agonist activity)

How are atypical or second generation antipsychotics different from typical antipsychotics?

What do second generation antipsychotics bind to?
Atypical antipsychotics, also known as the second-generation antipsychotics, differentiate themselves from typical antipsychotics by their ability to bind to
both serotonin and dopamine receptors
and their decreased extrapyramidal side effects.
Is risperidone a second generation antipsychotic?
Risperidone is a medication that works in the brain to treat schizophrenia. It is also known as a
second generation antipsychotic
