What is the definition or description of: antipsychotics?

Antipsychotics: These are medications used among other things to treat psychosis. There are two poorly named classes: the typicals, because they used to be typically used, and the atypicals, which are now typically used. They differ in that the so called atypicals are non-neuroleptics and interact with both serotonin and Dopamine receptos, while the typicals primarily affect dopamin receptors.

Antipsychotic: Also called neuroleptic, is a psychiatric medication used to manage psychosis. It works by altering responses at different brain receptors, mainly dopamine.
