Abstract
Antipsychotics, also termed neuroleptics or major tranquilizers have several chemical groups. The main two types are Typical and Atypical antipsychotics. The various psychosis conditions are mutually seen in older adults. Among the recently available atypical antipsychotics, Olanzapine, Risperidone, Clozapine, and Quetiapine have been the most widely studied in schizophrenia, bipolar disorder, and depression. Antipsychotics are often effective in treating troublesome mental health issues or various symptoms related to psychosis. The nature can guide the choice of atypical antipsychotic agent, the severity of the target symptom, and the medication least likely to cause harm to the patient. The study of antipsychotic drugs is useful for the treatment of mental health disorders (such as schizophrenia, mania disorders, etc.). First-generation antipsychotics (FGA) are an older class of drugs compared to second-generation antipsychotics (SGA). Antipsychotic drugs do not completely treat the psychosis conditions but help to reduce the symptoms.
