ABSTRACT It is now generally accepted that the use of second-generation, or atypical, antipsychotics for schizophrenia represents an advance over conventional antipsychotic agents. However, adherence continues to be a problem, as with other medications for chronic disorders. Long-acting formulations of conventional antipsychotics partly address adherence problems, but their use is limited by tolerability issues. This article provides practical advice to physicians on the characteristics of patients who would benefit from treatment with long-acting atypical antipsychotic agents and offers suggestions on how to initiate treatment.
A literature search for studies published between 1980 and 2003 that evaluated the treatment of patients with schizophrenia with long-acting atypical agents was conducted by using MEDLINE and EMBASE. The primary search parameters were "schizophrenia," "atypical," "antipsychotic," and "long-acting." As expected, long-acting risperidone was the only long-acting atypical agent identified; thus this article focuses on practical advice and suggestions on how to initiate therapy with long-acting risperidone.
From the results of the literature search and the discussion of a panel of experts at a meeting held in Dublin in 2003 and supported by Johnson & Johnson, it is possible to conclude that long-acting risperidone has demonstrated efficacy and tolerability, even among patients who are considered clinically stable on other antipsychotics. Most patients can switch safely and effectively to long-acting risperidone if appropriate strategies are applied. Long-acting risperidone provides a new and promising therapeutic option for the treatment of schizophrenia.

    ABSTRACT: To assess the feasibility and effectiveness of depot antipsychotic (flupenthixol decanoate) combined with an assertive monitoring programme (AMP) in first-episode schizophrenia. This was a prospective, non-comparative, longitudinal study conducted over 12 months assessing patient acceptance, adherence, outcome in domains of psychopathology, functionality and quality of life, and tolerability. Of 207 participants, 149 (72%) completed 12 months of treatment. Acceptance of and adherence to depot was good. Treatment response was achieved by 170 (82%) participants and remission by 124 (60%). Thirty-three (19%) responders relapsed and 10 (5%) participants met a priori criteria for treatment resistance. Treatment was generally well tolerated. Combination of depot antipsychotic with an AMP may be an effective and safe intervention in early phases of schizophrenia, and may be particularly suitable for resource-constrained settings.

    ABSTRACT: A long-term randomized trial of unstable patients with schizophrenia found no benefit of long-acting injectable (LAI) risperidone over oral treatment in preventing or delaying time to psychiatric hospitalizations or on clinical outcomes. The initial analyses did not examine whether benefits of LAI emerged in selected subgroups.Patients with schizophrenia or schizoaffective disorder who had been hospitalized within the past 2 years or judged to be at risk for hospitalization because of increasing psychiatric service use were randomly assigned to LAI risperidone 12.5 to 50 mg per injection biweekly or to the psychiatrist's choice of oral antipsychotics and followed for up to 2 years. The primary endpoint was psychiatric rehospitalization. Symptoms, quality of life, and global functioning were assessed through blinded videoconference interviews. Cox's regression and mixed effects models were used to assess difference in treatment effect within 12 subgroups defined by hospitalization at study entry, substance abuse, race, symptom severity, quality of life, body mass index, age, race or sex, or reported medication compliance.Mixed models and Cox's regression using up to 24 months of follow-up data showed no significant differences in treatment effect in 10 of 12 subgroups on psychiatric symptoms, quality of life, or time to hospitalization. With adjustment for multiple comparisons, treatment effect differed by race on substance use outcomes, with white participants showing more benefit from LAI than other groups.LAI risperidone showed no superiority to psychiatrist's choice of oral treatment in most clinically defined subgroups, although the white patients benefited more than the other groups on substance abuse outcomes.

    ABSTRACT: Resumen El cambio de antipsicóticos es un hecho frecuente en la práctica clínica y está sujeto a potenciales complicaciones clínicamente relevantes. Un grupo de expertos seleccionados por la Sociedad Española de Psiquiatría y la Sociedad Española de Psiquiatría Biológica ha revisado y discutido las pruebas provenientes de los ensayos clínicos y otros artículos relevantes para llegar a unas recomendaciones de consenso sobre el cambio de antipsicóticos. En este artículo se revisa toda la información que ha dado lugar a esas recomendaciones y que incluye: indica-ciones y contraindicaciones del cambio de antipsicóticos, aspectos farmacológicos, estrategias de cambio, el cambio por motivos de eficacia, el cambio por motivos de tolerabilidad (inclu-yendo los síntomas extrapiramidales y la discinesia tardía, el aumento de peso, los trastornos metabólicos, la hiperprolactinemia, la disfunción sexual, la sedación persistente y la prolon-gación del QT), el cambio por problemas de cumplimiento y el cambio de antipsicóticos en el trastorno bipolar. © 2011 SEP y SEPB.
