paliperidone-palmitate and Tourette-Syndrome

Paliperidone is FDA-approved for schizophrenia aged 12-17. However, the pharmacologic portfolio, extrapolation from adult studies, and the long track record of the parent drug, risperidone in child/adolescent psychiatric (CAP) population might expand its therapeutic potential.. EMBASE, Ovid MEDLINE, PubMed, Scopus, Web of Science, and Cochrane Database of Systemic Reviews were searched for all relevant studies of using paliperidone in child psychiatry up to date of February 2019.. Sound evidence base supports its use in early-onset schizophrenia, juvenile bipolar, and autism spectrum disorder. A modicum of evidence supports its use in Tourette syndrome and as adjuventia in attention-deficit/hyperactivity disorder (ADHD).. Paliperidone has some dynamic and kinetic superiority to the parent drug risperidone. Nonetheless, larger rigorous studies would define the real place of the atypical antipsychotic paliperidone in child and adolescent psychiatry. Until then, risperidone with its long track record in CAP population would remain a first option though.

Tourette's syndrome (TS) is a neuropsychiatric disorder of childhood onset characterized by multiple motor and phonic tics that fluctuate over time. Tic symptoms often improve by late adolescence, but some children and adults with TS may experience significant tic-related morbidity, including social and family problems, academic difficulties, and pain. When more conservative interventions are not successful, and when certain psychiatric co-morbidities further complicate the clinical profile, treating TS with an atypical antipsychotic medication may be a reasonable second-tier approach. However, the evidence supporting efficacy and safety of the atypical antipsychotics for treatment of tics is still very limited. The objective of this paper is to provide an updated overview of the role of atypical antipsychotics for treatment of TS, with evidence-based guidance on their use. Evidence for efficacy of different typical and atypical antipsychotics for treatment of tics was examined by conducting a systematic, keyword-related search of 'atypical antipsychotics' and 'Tourette's syndrome' in PubMed (National Library of Medicine, Washington, DC, USA). Four recent treatment consensus publications were also reviewed. This review focused on literature published from 2000 to 2013 and on available randomized controlled trials in TS. Evidence supporting the use of atypical antipsychotics for treatment of TS is limited. There are few randomized medication treatment trials in TS (i.e. risperidone, aripiprazole, ziprasidone), which employed varying methodologies, thereby restricting meaningful comparisons among studies. Future collaborations among clinical sites with TS expertise employing high-quality study design may better elucidate the role of atypical antipsychotics for treatment of TS.
