    Author: Parellada E.
    Journal: Curr Med Res Opin; 2006 Feb; 22(2):241-55. PubMed ID: 16466596.
    Abstract:
    BACKGROUND: Risperidone is the first atypical anti-psychotic available in a long-acting injectable formulation. OBJECTIVE: To provide an overview of the initial clinical experience gained with long-acting risperidone during clinical trials and in general treatment, including specific case studies, as well as providing practical advice on how to initiate treatment with this new drug. METHODS: Studies published between January 2002 and June 2005 that evaluated the pharmacokinetics, efficacy and safety of long-acting risperidone for the treatment of schizophrenia were reviewed, as identified from literature searches using Medline and EMBASE. Although not peer-reviewed, abstracts and posters on long-acting risperidone presented at key psychiatry and schizophrenia congresses during this period were also reviewed where available in the public domain. RESULTS: Clinical studies have consistently demonstrated that long-acting risperidone, available in dosage strengths of 25, 37.5 or 50 mg, given once every 2 weeks, is both effective and well tolerated in patients with schizophrenia. Furthermore, significant and sustained clinical improvement has been reported in patients switched to long-acting risperidone from other oral and long-acting antipsychotic agents. Several patients groups, including the young, the elderly and patients with schizoaffective disorder, have also been shown to derive significant benefit from long-acting risperidone. CONCLUSION: A wide variety of patient groups may benefit from treatment with long-acting risperidone, including patients with suboptimal efficacy, particularly as a result of partial compliance, patients experiencing side-effects with another antipsychotic agent or those with a first episode of schizophrenia. Furthermore, long-acting risperidone, with its assured medication delivery, should improve patient compliance and assist patients in achieving remission, an important step towards functional recovery.
