Paliperidone is a new second generation antipsychotic; in terms of pharmacology, it is an active metabolite of risperidone. Compared to risperidone, paliperidone should thus show more stable occupation of dopamine receptors in the brain, which on one the hand may lead to increased antipsychotic efficacy, and on the other hand to reduced incidence of adverse extrapyramidal effects. The case repo...

BACKGROUND Bipolar disorder (BD) is a chronic, relapsing, episodic mental illness associated with other psychiatric comorbidities. There is a substantial economic burden with BD, which makes it challenging to treat. The aim of this review is to evaluate the pharmacology, clinical efficacy, and safety data related to paliperidone extended release (ER) for the treatment of BD. METHODS A literat...

Paliperidone, the major active metabolite of risperidone, is a second-generation antipsychotic that has been developed as an extended-release (ER) tablet formulation that minimizes peak-trough fluctuations in plasma concentrations, allowing once-daily administration and constant drug delivery. Paliperidone ER has demonstrated efficacy in the reduction of acute schizophrenia symptoms in 6-week, ...

OBJECTIVE A subgroup of patients with Tourette's disorder (TD) has symptoms refractory to haloperidol, a standard therapeutic drug for TD. METHODS We report on three cases of pediatric and adolescent patients who were treated with paliperidone extended release. RESULTS In two cases, TD symptoms were remarkably improved by switching from haloperidol to paliperidone extended release, and in a...

The course of schizophrenia is characterized by multiple relapses, incomplete remission of symptoms, enduring cognitive deficits, and social and occupational functional impairments. Nonadherence to antipsychotic medication is a major determinant of this poor outcome. Long-acting injectable antipsychotics were developed specifically to address the nonadherence problem and are increasingly consid...

PURPOSE To review the use of paliperidone palmitate in treatment of patients with schizophrenia. METHODS Published clinical trial data for the development and utilization of paliperidone palmitate for the treatment of schizophrenia were assessed in this review. Four short-term, randomized, double-blind, placebo-controlled trials investigated the efficacy of paliperidone palmitate in acute exa...

BACKGROUND We analyzed data retrieved through a PubMed search of randomized, placebo-controlled trials of first-generation antipsychotic long-acting injectables (haloperidol decanoate, bromperidol decanoate, and fluphenazine decanoate), and a company database of paliperidone palmitate, to compare the benefit-risk ratio in patients with schizophrenia. METHODS From the eight studies that met ou...

BACKGROUND Paliperidone (9-hydroxyrisperidone), the major active metabolite of risperidone, has been introduced as a novel atypical antipsychotic agent in many countries. It is available both as an oral extended-release (ER) formulation and as a long-acting injection (paliperidone palmitate, PP), which have been approved for treating schizophrenia in the People's Republic of China since 2009 an...

Until now there has been no information available on drug interaction between paliperidone and TS-1(®), an oral anticancer drug containing a 5-fluorouracil derivative. The patient in the case presented here was a 39-year-old man with a 15-year history of schizophrenia. The patient's usual treatment of 2 mg/day of risperidone was changed to 3 mg/day of paliperidone extended release. He experienc...

OBJECTIVE To examine the tolerability of the recommended initiation doses for once-monthly injectable paliperidone palmitate in patients who have recently been diagnosed with schizophrenia and for whom high doses may pose tolerability concerns. METHODS A post hoc analysis from a 13-week double-blind study of patients with schizophrenia randomized 1:1:1:1 to placebo or paliperidone palmitate a...
