Achieving greater continuation of treatment is a key element to improve treatment outcomes in schizophrenia patients. However, reported treatment continuation can differ markedly depending on the study design. In a retrospective setting, treatment continuation remains overall poor among patients using antipsychotics. This study aimed to document the difference in treatment continuation between ...

Patient satisfaction with treatment is an important clinical index associated with the efficacy and adherence of treatment in schizophrenia. Although switching from oral antipsychotics to the long-acting injectable formulation may improve convenience, patient satisfaction has not been studied extensively. We carried out a 21-week, multicenter, randomized, open-label comparative study. A total o...

Methods A total of 984 patients meeting the The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for schizophrenia who switched their antipsychotic to paliperidone ER were recruited from 61 sites i...

Direct and indirect effects of the new psychotropic paliperidone extended-release (paliperidone ER) tablets on negative symptom improvement in schizophrenia were investigated using path analysis. A post hoc analysis of pooled data from three 6-week, double-blind, placebo-controlled studies of paliperidone ER in patients experiencing acute exacerbation was conducted. Regression analysis explored...

BACKGROUND The cost of schizophrenia in Japan is high and new long-acting injectable (LAI) antipsychotics might be able to reduce costs by causing a reduction of hospital stays. We aim to estimate budget effects of the introduction of a new 1-month LAI, paliperidone palmitate, in Japan. METHODS A budget impact analysis was conducted from a payer perspective. The model took direct costs of ill...

Many patients with schizophrenia receive long-term treatment with antipsychotic medication. Switching of antipsychotic medication due to lack of efficacy, tolerability issues, and partial/non-adherence is common. Despite this, consensus strategies for switching between antipsychotics are lacking. This manuscript provides practical recommendations for switching antipsychotic medication to ensure...

BACKGROUND We aimed to explore relations between symptomatic remission and functionality evaluation in schizophrenia patients treated with paliperidone extended-release (ER), as seen in a normal day-to-day practice, using flexible dosing regimens of paliperidone ER. We explored symptomatic remission rate in patients treated with flexibly dosed paliperidone ER by 8 items of Positive and Negative...

OBJECTIVE This open-label prospective study investigated the effects of paliperidone extended release (ER) on hostility in Thai patients with schizophrenia. BACKGROUND Patients diagnosed with schizophrenia may be hostile or exhibit aggressive behavior, which can occasion their admission to psychiatric hospital. Antipsychotic medications are often used to treat hostility and aggression in such...
