Psychiatric Drugs The development of psychiatric drugs to treat major mental illnesses such as schizophrenia and mood disorders has both revolutionized the field of mental health and provided insights into the biochemical basis for mental illness.

Antipsychotic Drugs and Schizophrenia Therapeutic medications for schizophrenia patients are classified as first-generation, second-generation, and third-generation antipsychotic drugs. First-generation drugs include chlorpromazine (brand name: Thorazine) and haloperidol (brand name: Haldol).

© Copyright 2011, Pearson Education, Inc. All rights reserved. Antipsychotic Drugs and Schizophrenia Second-generation drugs include clozapine (Clozaril), risperidone (Risperdal), olanzapine (Zyprexa), quetiapine (Seroquel), ziprasidone (Geodon), and apiprazadole(Abilify).

Antipsychotic Drugs and Schizophrenia First-generation antipsychotic drugs have been effective in reducing symptoms for many patients, but they also carry the potential for the development of severe movement-related motor problems. Second-generation and third-generation antipsychotic medications do not produce this particular side effect.

Antipsychotic Drugs and Schizophrenia Antipsychotic medications are believed to be clinically effective, and to involve the least number of adverse side effects, by virtue of a combination of actions upon subtypes of dopamine and serotonin receptors in the brain.

Drugs Used to Treat Depression Although they are effective, patients need to be on a restricted diet to avoid serious adverse side effects. Tricyclic antidepressants do not require dietary restrictions, but their effects on the cardiovascular system make them undesirable for certain patients.

© Copyright 2011, Pearson Education, Inc. All rights reserved. Drugs Used to Treat Depression Collectively, they are referred to as selective serotonin reuptake inhibitors (SSRIs). Third-generation antidepressants slow the reuptake of both serotonin and norepinephrine in the brain.

Drugs for Other Types of Mental Disorders Mania and extreme mood swings between mania and depression (bipolar disorder) are two mood disorders that have been treated successfully with lithium carbonate or valproate (brand name: Depakote).

Drugs for Other Types of Mental Disorders Also used are antipsychotic medications such as risperidone (brand name: Risperdal) and ziprasidone (brand name: Geodon), or a combination of antipsychotic and antidepressant medications (brand name: Symbyax).

Psychiatric Drugs, Social Policy, and Deinstitutionalization Since the 1960s, a growing number of psychiatric patients have been treated outside a centralized hospital or institution and placed in treatment-care clinics in the community.

Psychiatric Drugs, Social Policy, and Deinstitutionalization Although the policy of deinstitutionalization has sparked great debate and significant social problems remain, there is a growing consensus that mental-care treatment implemented in this manner is superior to institutionalization.
