Long-acting risperidone vs. placebo in the treatment of hospital inpatients with schizophrenia.
Maintenance treatment regimens for patients with schizophrenia are often suboptimal. Partial adherence and outright noncompliance are associated with symptom recurrence and increased likelihood of rehospitalization. Long-acting conventional neuroleptics have limited efficacy and are associated with treatment-limiting adverse events, while oral atypical antipsychotics have not improved adherence substantially. A long-acting formulation of risperidone, an atypical antipsychotic with proven efficacy, has been developed. Introduction of long-acting injectable treatment may be appropriate during inpatient hospitalization, when consequences of relapse are most evident. To support this intervention, a subanalysis of patients who were inpatients at study initiation was conducted from a 12-week, double-blind, placebo-controlled long-acting risperidone study (N = 214). Long-acting risperidone was associated with a significant reduction in total Positive and Negative Syndrome Scale (PANSS) score (mean change +/- standard error [S.E.] at endpoint: long-acting risperidone, -9.27 +/- 1.44, n = 133; placebo, 0.72 +/- 2.59, n = 41; P < 0.001), and a significantly higher rate of treatment response, defined as > or = 20% reduction in total PANSS score (50% vs. 27%, P < 0.05). Significantly more long-acting risperidone patients had endpoint Clinical Global Impressions (CGI) assessments of not ill, very mild or mild (32% vs. 5%; P < 0.01). Long-acting risperidone was well tolerated. Long-acting risperidone initiated during inpatient treatment may be an important strategy in improving long-term outcomes among patients with schizophrenia.
