Typical antipsychotics (also known as major tranquilizers, and first generation antipsychotics) are a class of antipsychotic drugs first developed in the 1950s and used to treat psychosis (in particular, schizophrenia). Typical antipsychotics may also be used for the treatment of acute mania, agitation, and other conditions.
The pharmacological basis for this distinction from other second generation antipsychotic drugs is unclear, though it has been suggested that quetiapine's comparatively lower dopamine receptor affinity and strong antihistamine activity might mean it could be regarded as more similar to sedating antihistamines in this context. While these issues ...

The difference between first- and second-generation antipsychotics is a subject of debate.

Ziprasidone was 15% more effective than lurasidone and iloperidone , approximately as effective as chlorpromazine and asenapine , and 9–13% less effective than haloperidol ...

Second-generation (atypical) antipsychotics: The concept of "atypicality" is from the finding that second generation antipsychotics (SGAs) have a greater serotonin/dopamine ratio than earlier drugs, and might be associated with improved efficacy (particularly for the negative symptoms of psychosis) and reduced extrapyramidal side effects.
