Abstract
To assess the bioequivalence of two 5-mg olanzapine orally disintegrating tablet (ODT) products, 2 randomized, open-label, single-dose, 2-way crossover studies were carried out under fasting or fed conditions. Blood samples were collected at scheduled times according to the study protocol. Statistical analysis of area under the concentration-time curve from time 0 to 168 hours (AUC0-t ), area under the curve from time zero to infinity (AUC0-∞ ), and peak plasma concentration (Cmax ) was conducted. Two formulations were considered bioequivalent if the 90% confidence intervals (CIs) of the geometric mean ratios for AUC0-t, AUC0-∞ , and Cmax were within the range of 0.80-1.25. Adverse events were recorded and evaluated throughout the studies. A total of 48 subjects with 24 in each study completed the 2 studies. In fasted subjects, the 90%CIs for the test product versus the reference product were 97.28%-105.13% for AUC0-t , 97.57%-105.54% for AUC0-∞ , and 90.94%-103.97% for Cmax . In fed subjects, the 90%CIs for AUC0-t , AUC0-∞ and Cmax were 99.73%-122.63%, 99.56%-121.75%, and 99.46%-120.46%, respectively. No serious adverse events were reported in the studies. The reference and the test product of 5-mg olanzapine ODT show comparable pharmacokinetic profiles under both fed and fasted conditions and were considered bioequivalent.

Kwan B, Rickwood DJ. A systematic review of mental health outcome measures for young people aged 12 to 25 years. BMC Psychiatry 2015; 15:279. [PMID: 26573269 PMCID: PMC4647516 DOI: 10.1186/s12888-015-0664-x] [Citation(s) in RCA: 58] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2015] [Accepted: 10/27/2015] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Mental health outcome measures are used to monitor the quality and effectiveness of mental health services. There is also a growing expectation for implementation of routine measurement and measures being used by clinicians as a feedback monitoring system to improve client outcomes. The recent focus in Australia and elsewhere targeting mental health services to young people aged 12-25 years has meant that outcome measures relevant to this age range are now needed. This is a shift from the traditional divide of child and adolescent services versus adult services with a transitioning age at 18 years. This systematic review is the first to examine mental health outcome measures that are appropriate for the 12 to 25 year age range. METHODS MEDLINE and PsychINFO databases were systematically searched to identify studies using mental health outcome measures with young people aged 12 to 25 years. The search strategy complied with the relevant sections of the PRISMA statement. RESULTS A total of 184 published articles were identified, covering 29 different outcome measures. The measures were organised into domains that consisted of eight measures of cognition and emotion, nine functioning measures, six quality of life measures, and six multidimensional mental health measures. No measures were designed specifically for young people aged 12 to 25 years and only two had been used by clinicians as a feedback monitoring system. Five measures had been used across the whole 12 to 25 year age range, in a range of mental health settings and were deemed most appropriate for this age group. CONCLUSIONS With changes to mental health service systems that increasingly focus on early intervention in adolescence and young adulthood, there is a need for outcome measures designed specifically for those aged 12 to 25 years. In particular, multidimensional measures that are clinically meaningful need to be developed to ensure quality and effectiveness in youth mental health. Additionally, outcome measures can be clinically useful when designed to be used within routine feedback monitoring systems.

Abstract
The onset of severe, chronic or recurrent psychiatric illnesses, such as schizophrenia-spectrum and bipolar disorders, is a dramatic clinical event often detectable during adolescence and even in childhood. At any age, pharmacotherapy, along with enhancement of social skills and family support, is the mainstay for the management of such disorders. The aim of this review is to critically analyze findings from randomized controlled trials (RCTs) that have investigated the clinical utility of second-generation antipsychotics (SGAs) for the treatment of early-onset schizophrenia and bipolar disorders. Eighteen studies were considered, all of which were unfortunately impaired by methodologic limitations, such as the paucity of long-term data and lack of a three-arm comparison (SGA vs SGA vs placebo). Nevertheless, the results of this review allow us to suggest the effectiveness of three SGAs (aripiprazole, olanzapine, and risperidone) in the short-term treatment of both early-onset schizophrenia and bipolar mania, although such agents show different safety profiles. The use of clozapine should be strictly limited to patients with non-affective, psychotic symptoms who do not respond to any of these three SGAs. In contrast, the use of quetiapine and ziprasidone in young patients with either affective or non-affective psychosis is not yet supported by evidence-based information. Given our findings, further studies are urgently required to identify the best treatment option(s) for pediatric bipolar disorder (especially the depressive phase) and the long-term management of early-onset schizophrenia.
