The first major tranquilizer or antipsychotic medication, chlorpromazine (Thorazine), a typical antipsychotic, was discovered in 1951 and introduced into clinical practice shortly thereafter. Clozapine (Clozaril), an atypical antipsychotic, fell out of favor due to concerns over drug-induced agranulocytosis. Following research indicating its effectiveness in treatment-resistant schizophrenia and the development of an adverse event monitoring system, clozapine re-emerged as a viable antipsychotic. According to Barker (2003), the three most-accepted atypical drugs are clozapine, risperidone, and olanzapine. However, he goes on to explain that clozapine is usually the last resort when other drugs fail. Clozapine can cause agranulocytosis (a decreased number of white blood cells), requiring blood monitoring for the patient. Despite the effectiveness of clozapine for treatment-resistant schizophrenia, agents with a more favorable side-effect profile were sought-after for widespread use. During the 1990s, olanzapine, risperidone, and quetiapine were introduced, with ziprasidone and aripiprazole following in the early 2000s. The atypical anti-psychotic paliperidone was approved by the FDA in late 2006.
