Iloperidone for the Treatment of Schizophrenia

OBJECTIVE: To review the pharmacology, pharmacokinetics, efficacy, and safety data of iloperidone for the treatment of schizophrenia. DATA SOURCES: Data were selected by searching Pre-MEDLINE, MEDLINE, and International Pharmaceutical Abstracts (1966 January 2010). Abstracts, scientific posters, and unpublished data provided by the manufacturer in the English language were also assessed. STUDY SELECTION AND DATA EXTRACTION: All published data including pharmacologic, pharmacokinetic, pharmacodynamic, and clinical studies related to iloperidone were considered for inclusion. Selected studies included randomized controlled trials, abstracts, and posters presented at national scientific meetings providing pertinent data. data synthesis: Iloperidone is a benzisoxazole phenylethanone with a higher affinity for serotonin-2a than dopamine-2 receptors. The recommended therapeutic total daily dose is 12-24 mg divided in 2 doses titrated over 1 week to avoid orthostasis. Acute, 6-week, randomized, placebo-controlled, and active-controlled studies demonstrated iloperidone’s efficacy in reducing psychotic symptoms according to changes in the total positive and negative symptom scale (PANSS-T) score from baseline. A long-term maintenance trial demonstrated similar efficacy with haloperidol in preventing time to relapse. Pharmacogenomic studies reported possible single nucleotide polymorphisms related to QT interval prolongation and efficacy with iloperidone. Common adverse effects included dizziness, dry mouth, and sustained orthostasis occurring more frequently with higher doses. Weight gain is possible at any dose. Additionally, studies showed that QTc interval prolongation may be dose related. The incidence of extrapyramidal symptoms appears to be low across all dosage ranges; however, akathisia may be more frequent with higher doses. CONCLUSIONS: Iloperidone demonstrated efficacy in acute exacerbations and long-term maintenance in adults with schizophrenia. Caution may be warranted in elderly patients and patients with cardiac disease, due to orthostasis. Further studies regarding pharmacogenomic testing related to the drug’s efficacy and tolerability are needed to justify its routine use in practice.

Relative Bioavailability of Two Oral Formulations of Risperidone 2 mg: A Single-Dose, Randomized-Sequence, Open-Label, Two-Period Crossover Comparison in Healthy Brazilian Volunteers

Background: Risperidone (RSP) is a benzisoxazole antipsychotic agent used to treat schizophrenia and other psychiatric illnesses in adults and children (including those with autism). After oral administration, RSP is completely absorbed from the gastrointestinal tract and undergoes hydroxylation to yield 9-hydroxyrisperidone (9-OH-RSP), an active metabolite that has a pharmacologic profile and potency similar to RSP. Objectives: The aims of this study were to compare the relative bioavailability of a pharmaceutical-equivalent (test) formulation with a reference formulation of oral RSP 2 mg, both available commercially on the Brazilian pharmaceutical market, and to generate data regarding the oral bioavailability of the tested drug in healthy Brazilian volunteers. Methods: This single-dose, randomized-sequence, open-label, 2-period crossover study was conducted in healthy Brazilian volunteers from August to December 2008. Subjects were randomly assigned to receive the test formulation followed by the reference formulation or vice versa, with a 30-day washout period between doses. Study drugs were administered after a 12-hour overnight fast. For pharmacokinetic analysis, blood samples were drawn at 0 (baseline), 0.25, 0.5, 1, 1.5, 3, 5, 8, 12, 24, 48, 72, 96, and 120 hours after administration. Plasma concentrations of RSP and 9-OH-RSP were determined using LC-MS/MS. The test and reference formulations were to be considered bioequivalent if the 90% CIs for the geometric mean test/reference ratios were within a predetermined range of 80% to 125%, in accordance with the policies of the Brazilian Sanitary Surveillance Agency and the US Food and Drug Administration. Tolerability was determined using clinical assessments, monitoring of vital signs, analysis of laboratory test results, and subject interviews regarding adverse events. Results: A total of 22 subjects were enrolled (11 men, 11 women; mean [SD] age, 32 [12] years [range, 18-58 years]; weight, 70.4 [11.9] kg [range, 50-103 kg]; height, 1.67 [0.08] m [range, 1.56-1.80 m]; and body mass index, 25 [4] kg/m(2) [range, 18-29 kg/m(2)]). For RSP, mean (SD) C-max values were 12.6 (2.7) and 16.0 (2.3) ng/mL for the test and reference formulations, respectively. For 9-OH-RSP, mean C-max values were 17.8 (1.3) and 21.0 (1.7) ng/mL for the test and reference formulations. The 90% CIs for the mean test/reference ratios for RSP C-max, AUC(0-120), and AUC(0-infinity) were 74% to 82%, 75% to 85%, and 76% to 85%, respectively, and 83% to 87%, 75% to 79%, and 75% to 78% for 9-OH-RSP. The related adverse events (headache, low back pain, drowsiness, standing hypotension, local postvenipuncture ecchymoses, insomnia, nausea, and vomiting) were transient and mild. Conclusions: This single-dose study found that the test and reference formulations of oral RSP 2 mg did not meet the Brazilian and US regulatory criteria for bioequivalence in these fasting, healthy volunteers. The study formulations appeared to be well tolerated. (Clin Ther 2010;32:2106-2115) (C) 2010 Elsevier HS Journals, Inc.

Risperidone as a treatment for Tourette’s syndrome

Background: An open-label trial was performed to assess the efficacy and safety of risperidone, a benzisoxazole derivative with potent D-2 and 5-HT2 antagonism, for treatment of Tourette’s syndrome. Method: Thirty-eight patients with Tourette’s syndrome volunteered to take risperidone for treatment of their tics. All patients had failed to respond adequately to conventional treatments (with neuroleptics such as haloperidol and/or with the alpha(2)-adrenergic agonist clonidine) or had suffered from intolerable side effects from such treatments. Patients were rated for tic severity by the Yale Global Tic Severity Scale (YGTSS) before treatment and after 1 month of treatment with risperidone. Patients were monitored carefully for side effects and clinical response. Results: Of the 38 patients, 8 discontinued risperidone treatment before the end of the trial because of intolerable side effects. At the end of the 4-week trial, 22 patients (58%) were improved, 7 patients (18%) had no appreciable change in their symptoms, and 1 patient (3%) had a documented worsening of tics. Doses of risperidone at the end of the trial ranged from 0.5 mg to 9 mg/day (mean = 2.7 mg/day). Conclusion: This open clinical trial suggests that risperidone may be a promising alternative to conventional medications used for treating the symptoms of Tourette’s syndrome.

Neuroleptic malignant syndrome with risperidone

Neuroleptic malignant syndrome is thought to be a result of dopamine D-2 receptor blockade in the striatum of the basal ganglia. Risperidone, a benzisoxazole derivative antipsychotic, has high serotonin 5-HT2 receptor blockade and dose-related D-2 receptor blockade. The high ratio is believed to impart the low frequency of extrapyramidal symptoms with risperidone at low dosages. With this low frequency of extrapyramidal symptoms, it was thought the frequency of neuroleptic malignant syndrome might also be lowered. A 73-year-old woman developed neuroleptic malignant syndrome after monotherapy with risperidone. The syndrome reversed after discontinuing risperidone and starting treatment with dantrolene and bromocriptine. It appears that the protection from extrapyramidal side effects observed with risperidone does not ensure protection from neuroleptic malignant syndrome.

Somatic hybrid plants between the forage legumes Medicago sativa L and Medicago arborea L

Interspecific somatic hybrid plants were obtained by symmetrical electrofusion of mesophyll protoplasts of Medicago sativa with callus protoplasts of Medicago arborea. Somatic hybrid calli were picked manually from semi-solid culture medium after they were identified by their dual color in fluorescent light. Twelve putative hybrid calli were selected and one of them regenerated plants. The morphogenesis of the somatic hybrid calli was induced by the synthetic growth regulator 1,2 benzisoxazole-3-acetic acid. Somatic hybrid plants showed intensive genome rearrangements, as evidenced by isozyme and RFLP analysis. The morphology of somatic hybrid plants was in general intermediate between the parents. The production of hybrids by protoplast fusion between sexually incompatible Medicago species is related to the in vitro responsiveness of the parental protoplasts. The possibility of using somatic hybrid plants in alfalfa breeding is discussed.
