Clozapine (Clozaril - Sandoz), an antipsychotic drug, was first marketed in the USA three years ago (Medical Letter, 32:3, 1990). Because of its hematological toxicity, the US Food and Drug Administration approved the drug only for patients with schizophrenia who cannot tolerate or do not respond to standard antipsychotic drugs.

Clozapine (Clozaril - Sandoz), a dibenzodiazepine antipsychotic drug that has been available in Europe for many years, was recently approved for marketing by the US Food and Drug Administration. Because of its toxicity, the labeling for clozapine recommends using the drug only for schizophrenic patients who have not responded adequately to standard antipsychotic drugs or have had intolerable adverse effects.

The FDA has announced that prescribers, pharmacies, and patients are no longer required to participate in a Risk Evaluation and Mitigation Strategy (REMS) program for the second-generation antipsychotic drug clozapine (Clozaril, and others).

The FDA has approved the atypical antipsychotic pimavanserin (Nuplazid – Acadia) for treatment of hallucinations and delusions associated with Parkinson's disease. It is the first drug to be approved in the US for this indication.

Olanzapine (Zyprexa - Lilly), a thienobenzodiazepine that structurally resembles and binds to many of the same receptors as clozapine (Clozaril), is now available in the USA for treatment of schizophrenia and other psychotic disorders.

Risperidone (Risperdal - Janssen), a benzisoxazole derivative, is now available in the USA for treatment of schizophrenia and other psychotic disorders.

Quetiapine (Seroquel - Zeneca), a dibenzothiazepine derivative, has been approved by the FDA for treatment of schizophrenia and other psychotic disorders. It is a new addition to the 'atypical' antipsychotics, which include olanzapine (Zyprexa - Medical Letter, 39:5, 1997), risperidone (Risperdal) and clozapine (Clozaril). Atypical antipsychotic drugs generally are less likely to cause extrapyramidal symptoms than older drugs such as haloperidol (Haldol, and others) or the phenothiazines.

A recent supplement to the Journal of Clinical Psychiatry, titled "The Expert Consensus Guideline Series: Optimizing Pharmacologic Treatment of Psychotic Disorders," concluded that most experts endorsed use of second-generation (atypical) antipsychotics rather than first-generation drugs, with risperidone (Risperdal - Janssen) the top choice for first episodes, multiple episodes or switches from another drug (JM Kane et al, J Clin Psychiatry 2003; 64 suppl 12:5). The supplement was sponsored by Janssen.

Glycopyrrolate (Robinul, and others), a synthetic muscarinic receptor antagonist, has been used off-label for many years for treatment of excessive drooling in patients with Parkinson’s disease, in patients taking clozapine for schizophrenia, and in developmentally disabled children.1-3 It has now been approved by the FDA as Cuvposa (Shionogi) for use specifically in children 3-16 years old with severe chronic drooling due to a neurologic condition, such as cerebral palsy. It is being marketed as an oral solution, which will permit more precise weight-based dosing than was possible with the...

The FDA has approved lurasidone (Latuda - Sunovion), a new second-generation antipsychotic, for oral treatment of schizophrenia in adults.
