The atypical antipsychotics ( AAP ), also known as second generation antipsychotics ( SGAs) and serotonin –dopamine antagonists ( SDAs ), [ 1][ 2] are a group of antipsychotic drugs (antipsychotic drugs in general are also known as tranquilizers and neuroleptics, although the latter is usually reserved for the typical antipsychotics) largely ...
Typical antipsychotic. 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.
There are two main categories of antipsychotics: typical and atypical. Typical antipsychotics have been around longer and are known as first-generation antipsychotics. Atypical antipsychotics are ...

Clozapine is a psychiatric medication and was the first atypical antipsychotic (also called second-generation antipsychotic) to be discovered. [6] It is primarily used to treat people with schizophrenia and schizoaffective disorder who have had an inadequate response to two other antipsychotics, or who have been unable to tolerate other drugs due to extrapyramidal side effects.
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.

The second-generation antipsychotic olanzapine is thought to have a rebound-induced hyperthermia, which may be mediated by serotonin receptors. Hyperthermia, or elevated core body temperature, is associated with neuroleptic malignant syndrome, a potentially lethal syndrome that commonly occurs due to excessive D2R antagonism.
