  FIRST AND SECOND GENERATION OF  ANTI-PSYCHOTICS:  MECHANISMS AND SIDE EFFECTS First and second-generation antipsychotics (also known as typical and atypical antipsychotics, respectively) are medications used primarily to manage psychosis, including schizophrenia and other psychotic disorders. They differ in their mechanisms of action and side effect profiles.
