Aims: We examined prescription patterns in maintenance treatment for recovered bipolar patients and compared these with acute treatments., Methods: Using retrospective methods, the bipolar patients in clinical recovery (Clinical Global Impression Bipolar Version score ≤ 2 for 6 months) after acute episode were selected. We reviewed differences between prescription patterns at remission and after a maintenance period of at least 6 months., Results: A total of 340 bipolar disorder patients were selected. During the maintenance period, more than half of the patients (192, 56.5%) took a mood stabilizer (MS) + antipsychotic (AP) combination. Among the MS, valproate (149, 43.8%) was most prescribed, and lithium (98, 28.8%) was second, but as patients moved into maintenance treatment, lithium use decreased, and the use of lamotrigine (86, 25.3%) increased. Preferred AP were quetiapine (125, 36.8%), aripiprazole (67, 19.7%), risperidone (48, 14.1%), and olanzapine (39, 11.5%). The use of olanzapine in maintenance was greatly decreased compared with that during acute treatment (67, 19.7%). Most patients did not take an antidepressant (AD), but the proportion using one or more AD was increased during maintenance (17.9% to 30.3%), and bupropion (28, 8.2%) was the preferred AD. Doses were decreased in all drugs, but lamotrigine was maintained at a dose of 133.2 ± 68.5 mg/day., Conclusions: The most common prescription combination for bipolar maintenance treatment was MS + AP. The use of AP was decreased, whereas the use of AD in combination with MS and/or AP was increased. The doses of MS and AP were generally decreased during the maintenance periods, with the exception of lamotrigine., (© 2015 The Authors.

We reviewed the extant literature to evaluate the current evidence regarding the efficacy and safety of anticonvulsants in the treatment of obsessive-compulsive and related disorders. Relevant literature was accessed using the Cochrane database, embase and PubMed on 29 October 2013. Prospective studies examining the efficacy of anticonvulsants in obsessive-compulsive and related disorders were included. Case reports, case series, and retrospective studies were excluded. A total of 10 studies were included in this review. The studies of obsessive-compulsive disorder, except for two negative studies, showed favorable efficacy results of anticonvulsants. In one study on body dysmorphic disorder, levetiracetam showed favorable efficacy. In two lamotrigine studies for pathologic skin-picking, the efficacy findings were inconsistent. In one trichotillomania study, topiramate had reduced hair-pulling symptoms. Despite limited evidence, our review suggests that anticonvulsants have a potential role in the treatment of obsessive-compulsive and related disorders., (© 2014 The Authors.

Aim: We compared the 1-year rehospitalization rates of first-episode bipolar manic patients who were discharged while being treated with lithium or valproate in combination with an atypical antipsychotic., Methods: We investigated the rehospitalization status of first-episode bipolar manic patients who were discharged between 1 January 2003 and 31 December 2010 while they were taking lithium or valproate in combination with aripiprazole, olanzapine, quetiapine, or risperidone. Rehospitalization rates during a 1-year period after discharge were compared between the group receiving lithium plus an atypical antipsychotic and the group receiving valproate plus an atypical antipsychotic using the Kaplan-Meier method. A Cox regression model was used to analyze covariates hypothesized to affect time to rehospitalization., Results: The rehospitalization rate was 17.3% during the 1-year follow-up period. We found significant differences in the rehospitalization rates of patients in the lithium (23.1%) and the valproate (13.3%) groups using the Kaplan-Meier formula. According to Cox proportional hazards regression analysis, higher Clinical Global Impression-Bipolar Version-Severity score at discharge (P = 0.005) and lithium treatment (P = 0.055) contributed to the risk of rehospitalization., Conclusion: Treatment with valproate and an atypical antipsychotic can be more effective than treatment with lithium and an atypical antipsychotic in preventing rehospitalization during the 1 year after hospitalization due to a first manic episode in patients with bipolar I disorder. Higher Clinical Global Impression-Bipolar Version-Severity scores at discharge also negatively affected rehospitalization rates., (© 2014 The Authors.

The aim of this study was to review the efficacy and safety of atypical antipsychotics, comparing within class, placebo, or compared to another active treatment for delirium. A literature search was conducted using PubMed, EMBASE, and the Cochrane database (1 January 1990-5 November 2012). Selection criteria for review were prospective, controlled studies (comparison studies), using validated delirium rating scales as outcome measures. A total of six prospective, randomized controlled studies were included in the review. It was found that atypical antipsychotics are effective and safe in treating delirium, even though there seemed to be no difference between each agent. In particular, comparison studies with haloperidol showed that the efficacy of atypical antipsychotics was similar to that of low-dose haloperidol. It was concluded that atypical antipsychotics appear to be effective and tolerable in the management of delirium, even though the evidence is limited., (© 2013 The Authors.

Aims: The goal of this study was to assess the efficacy and tolerability of tianeptine in combination with selective serotonin re-uptake inhibitor (SSRI) in partial responders or non-responders to SSRI monotherapy., Methods: In this prospective, open-label, 6-week study, 150 patients with major depressive disorder who had previously not responded or partially responded to SSRI monotherapy were recruited. Tianeptine was given in combination with an SSRI for 6 weeks., Results: Significant improvements were observed in the mean scores of the Hamilton Depression Rating Scale (HDRS), Montgomery-Åsberg Depression Rating Scale (MADRS), and Clinical Global Impression-Severity (CGI-S). The change in the mean HDRS, MADRS, and CGI-S scores was significant from week 1. The response rates were 64.7% (HDRS) and 68.7% (MADRS), and the remission rates were 34.0% (HDRS) and 42.0% (MADRS) at week 6. Thirty-six patients (24.0%) reported adverse events that were determined by the investigator to be related to one of the study drugs. The tianeptine and SSRI combination was generally well-tolerated., Conclusions: A combination strategy with tianeptine may be an effective and well-tolerated tool for patients who have failed to adequately respond to SSRI monotherapy., (© 2013 The Authors.

The objective of the present study was to evaluate changes in platelet counts on three different kinds of antidepressant. All subjects (n = 131) in their drug-naïve state had been diagnosed with depression. Escitalopram (n = 42), venlafaxine (n = 50) and bupropion (n = 39) were prescribed, and platelet count was measured before and after 1 month of treatment and compared. Decrease in platelet count on escitalopram was significant, while the others were not. These findings suggest that escitalopram may be associated with decreased platelet count, and bupropion is less likely to exert an influence on platelet count., (© 2012 The Authors.

Aims: The goal of the present study was to evaluate the efficacy of risperidone combined with mood stabilizers for treating bipolar mixed state., Methods: The present study was a 24-week, open-label, combination, prospective investigation of the efficacy of risperidone in combination with mood stabilizers. Risperidone (1-6 mg/day) was given in combination with mood stabilizers in flexible doses according to clinical response and tolerability for 114 patients in mixed or manic episode., Results: Forty-four patients met our criteria for mixed state bipolar disorder and 70 met the criteria for pure mania. Mean age for the subjects was 39.0 +/- 11.0 years and 55.3% were female. The combination of risperidone with mood stabilizers significantly improved the scores on the Young Mania Rating Scale (YMRS), 17-item Hamilton Rating Scale for Depression (HAMD), 18-item Brief Psychiatric Rating Scale (BPRS), Global Assessment Scale (GAS), and Clinical Global Impression Scale for use in bipolar illness Severity (CGI-BP) at 24 weeks (P < 0.0001). Analysis of the YMRS, BPRS, GAS, and CGI-BP scores showed significant improvement in both the manic and mixed groups. The rate of response in YMRS scores was 84.2% (n = 96) and the rate of YMRS remission was 77.2% (n = 88) at week 24 in the total population. Seventy-four patients met both YMRS < or = 12 and HAMD < or = 7 at week 24 (64.9%). Risperidone was well tolerated, and adverse events were mostly mild., Conclusion: The combination of risperidone with mood stabilizers was an effective and safe treatment for manic symptoms and coexisting depressive symptoms of bipolar disorder.
