The FDA has approved lumateperone (Caplyta — Intracellular Therapies), an oral second-generation antipsychotic, for once-daily treatment of schizophrenia in adults. It is the 13th second-generation antipsychotic drug to be approved by the FDA for this indication.

Invega Hafyera (Janssen), a long-acting, extended-release (ER) formulation of the second-generation antipsychotic paliperidone palmitate, has been approved by the FDA for twice-yearly IM treatment of schizophrenia in adults who have been adequately treated with another injectable ER formulation of the drug (Invega Sustenna or Invega Trinza). It is the first drug to become available in the US for twice-yearly treatment of schizophrenia.

The FDA has approved the second-generation antipsychotic drug cariprazine (Vraylar — Abbvie) for adjunctive treatment of major depressive disorder (MDD) in adults. Cariprazine was previously approved for treatment of schizophrenia and bipolar depression, and for acute treatment of manic or mixed episodes associated with bipolar I disorder.

A recently published retrospective cohort study in patients 30-74 years old has led to headlines in the media warning that use of atypical antipsychotic drugs doubles patients’ risk of sudden cardiac death. Typical antipsychotics have long been associated with this risk. In this study, however, the incidence of sudden cardiac death was similar with typical and atypical antipsychotics: about 1 in 340 person-years among the patients who took typical (first generation) antipsychotics such as haloperidol (Haldol, and others) and 1 in 360 personyears among those who took atypical...

Paliperidone (Invega - Janssen) has been approved by the FDA in an extended-release formulation for treatment of schizophrenia. It is the primary active metabolite of the second-generation antipsychotic risperidone (Risperdal - Janssen), which is scheduled to lose its patent exclusivity in December 2007.

The FDA has approved the marketing of iloperidone (Fanapt – Vanda), a second-generation antipsychotic, for treatment of schizophrenia. Iloperidone is chemically related to risperidone (Risperdal, and others).

The FDA has approved the oral, once-daily, second-generation antipsychotic brexpiprazole (Rexulti – Otsuka/Lundbeck) for treatment of schizophrenia and as an adjunct to antidepressants for treatment of major depressive disorder (MDD). Aripiprazole (Abilify), a structurally similar second-generation antipsychotic also comarketed by Otsuka (with BMS), recently became available generically.

The FDA has reported that 5106 elderly patients with dementia treated with atypical (second generation) antipsychotics in 17 randomized controlled trials had a higher mortality rate (4.5% vs. 2.6%) than those receiving placebo. Most of the deaths were due to cardiovascular and infectious causes (such as pneumonia). The drugs used in the trials were aripiprazole (Abilify), olanzapine (Zyprexa), quetiapine (Seroquel), and risperidone (Risperdal). As the increase in mortality was considered a class effect, the FDA advisory also included ziprasidone (Geodon), clozapine (Clozaril) and the...

Oral antipsychotic drugs used for treatment of schizophrenia, schizoaffective disorder, delusional disorder, and other manifestations of psychosis or mania are listed in Table 1. Parenteral antipsychotic drugs used for treatment of these disorders are listed in Table 2.

The FDA recently cleared the AmpliChip CYP450 Test (Roche), which analyzes blood-derived DNA to detect genetic variations in the activity of cytochrome P450 (CYP) enzymes CYP2D6 and CYP2C19 and determines the metabolizer status of the patient. The test is intended to help guide clinicians in prescribing individualized drug therapy. About 25% of all drugs, including many antidepressants and antipsychotics, are substrates of either CYP2D6 or CYP2C19. The test is being promoted initially to psychiatrists.
