What are typical and atypical antipsychotic drugs?
Typical antipsychotic drugs act on the dopaminergic system, blocking the dopamine type 2 (D2) receptors. Atypical antipsychotics have lower affinity and occupancy for the dopaminergic receptors, and a high degree of occupancy of the serotoninergic receptors 5-HT2A.
What is the difference between typical and atypical antipsychotics?
The key characteristic of atypical antipsychotics is that the drugs effectively treat psychoses at doses which do not induce extra pyramidal adverse effects. In contrast, the typical drugs tend to cause extra pyramidal adverse effects at the doses which are effective for psychotic symptoms.
What are examples of atypical antipsychotics?
Atypical agents currently available include clozapine (Clozaril), risperidone (Risperdal), olanzapine (Zyprexa), quetiapine (Seroquel), ziprasidone (Geodon), aripiprazole (Abilify), and paliperidone (Invega), the active metabolite of risperidone.
What are typical antipsychotic drugs?
The typical, or conventional, antipsychotics were first developed in the 1950s. Haldol (haloperidol) and Thorazine (chlorpromazine) are the best known typical antipsychotics.

What is the difference between 1st 2nd and 3rd generation antipsychotics medication?
The major mechanistic difference between first- and second-generation antipsychotics is the preferential docking and receptor binding with D2 and D3 (partial agonist activity), with very few muscarinic and adrenergic alpha-1, and histamine-1 effects. SGAs also tend to blockade 5HT2A receptors.
