Mania (or manic episodes) is a common symptom of bipolar disorder and is frequently accompanied by hyperactivity and delusions; given the cost and resources available, there is a paucity of evidence for direct comparison of different drugs.. We aimed to provide evidence-based recommendations on the efficacy of overall currently used pharmacological treatments for patients with acute bipolar mania.. We conducted a systematic review and network meta-analysis (NMA) using a Bayesian network frame. We searched the primary literature databases without language restrictions until Dec 18, 2021, for reports of randomized controlled trials (RCTs) of suspected antimanic drugs used as monotherapy for patients with acute bipolar mania, with the primary outcomes being efficacy (mean difference (MD), standardized mean difference (SMD) in the change of mania score).. Eighty-seven studies were included in which 18,724 manic participants (mean age = 34.6 years, with 50.36% males) were allocated at random to one of 25 active medication drug therapies or placebo, resulting in 87 direct comparisons on 192 data points. Tamoxifen (- 22·00 [- 26·00 to - 18·00]) had the best efficacy over the placebo. Meanwhile, risperidone (- 6·60 [- 8·40 to - 4·90]) was substantially more effective than placebo in treating acute mania. Carbamazepine, haloperidol, ziprasidone, cariprazine, olanzapine, quetiapine, aripiprazole, lithium, paliperidone, asenapine, and divalproex were noticeably more effective than placebo.. Overall, tamoxifen appears to be the most effective of the currently known pharmaceutical therapy available to treat acute mania or manic episodes; however, this conclusion is restricted by the scale of RCTs conducted, and risperidone was found to be the most effective medication among antipsychotics. Carbamazepine, haloperidol, ziprasidone, cariprazine, olanzapine, quetiapine, aripiprazole, lithium, paliperidone, asenapine, and divalproex were noticeably effective in treating acute mania or manic episodes.

Insufficient treatment of psychosis often manifests as violent and aggressive behaviors that are dangerous to the patient and others, and that warrant treatment strategies which are not considered first-line, evidence-based practices. Such treatment strategies include both antipsychotic polypharmacy (simultaneous use of 2 antipsychotics) and high-dose antipsychotic monotherapy. Here we discuss the hypothesized neurobiological substrates of various types of violence and aggression, as well as providing arguments for the use of antipsychotic polypharmacy and high-dose monotherapy to target dysfunctional neurocircuitry in the subpopulation of patients that is treatment-resistant, violent, and aggressive. In this review, we focus primarily on the data supporting the use of second-generation, atypical antipsychotics both at high doses and in combination with other antipsychotics.

An assessment of the effects of asenapine on QTc interval in patients with schizophrenia revealed a discrepancy between the results obtained by two different methods: an intersection-union test (IUT) (as recommended in the International Conference on Harmonisation E14 guidance) and an exposure-response (E-R) analysis. Simulations were performed in order to understand and reconcile this discrepancy. Although estimates of the time-matched, placebo-corrected mean change in QTc from baseline (ddQTc) at peak plasma concentrations from the E-R analysis ranged from 2 to 5 ms per dose level, the IUT applied to simulated data from the E-R model yielded maximum ddQTc estimates of 7-10 ms for the various doses of asenapine. These results indicate that the IUT can produce biased estimates that may induce a high false-positive rate in individual thorough QTc trials. In such cases, simulations from an E-R model can aid in reconciling the results from the two methods and may support the use of E-R results as a basis for labeling.
