What are the three main differences between typical and atypical antipsychotics?
Atypical carry a lower risk of extrapyramidal side effects, have a beneficial effect on negative symptoms and cognitive impairment, and are suitable for treatment-resistant patients.
5 of 8

They act on the dopamine system by blocking D2 receptors. However, they only temporarily occupy the D2 receptors and then rapidly dissociate to allow normal dopamine transmission.
