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 difference between first- and second-generation antipsychotics is a subject of debate. The second-generation antipsychotics are generally distinguishable by the presence of 5HT2A receptor antagonism and a corresponding lower propensity for extrapyramidal side effects compared to first-generation antipsychotics.

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.
