cariprazine and Mental-Disorders

Cariprazine is a new atypical antipsychotic drug approved for the treatment of schizophrenia and bipolar disorders.. we searched the published randomized controlled-trials (RCT) to review cariprazine efficacy and tolerability using the databases (PubMed, EUDRACT, ClinicalTrials.gov and Cochrane Central Register of Controlled Trials) for cariprazine role in managing the following psychiatric conditions (schizophrenia, bipolar mania, bipolar depression and major depressive disorder). A meta-analysis was conducted using the identified 13 clinical trials to assess efficacy using with the outcomes: positive and negative syndrome scale (PANSS), clinical global impressions - severity of Illness (CGI-S), young mania rating scales (YMRS), Montgomery Asberg depression rating scale (MADRS) and Hamilton rating scale for depression (HAM-D). The risk of discontinuation due to adverse effects and common side effects were examined.. The mean difference in change from baseline for PANSS was -6.23 (95% Confidence Interval (CI) -7.18, -5.28) favoring cariprazine treatment (p<0.00001). Similarly, mean difference for CGI-S was -0.36 (95% CI -0.41, -0.30), YMRS -5.64 (95% CI -6.86, -4.43), MADRS -1.43 (95% CI -1.88, -0.99) and HAM-D -1.52 (95% CI -2.28, -0.76). The risk ratio (RR) of discontinuing due to adverse events was 1.18 (95% CI 1.01, 1.38) meaning risk increased by 18% in cariprazine group with RR for EPS related side effects 2.82 (95% CI 2.47, 3.22) reflecting an increased risk of experiencing EPS related side effects by 182%. Cariprazine was also associated with an increased incidence of side effects such as akathisia, nausea and insomnia.. Cariprazine demonstrates significant improvements in symptom intensity control in patients suffering from psychiatric conditions including schizophrenia, bipolar disorders and depression and is considered well-tolerated with similar rates of trials discontinuation; however, cariprazine was associated with a higher risk of EPS side effects. These findings will guide psychiatrists and pharmacists in their clinical role for supporting psychiatric patients care.

Second generation antipsychotics (SGAs) are effective options in the treatment of schizophrenia and mood disorders, each with characteristic efficacy and safety features. In order to optimize the balance between efficacy and side effects, it is of upmost importance to match compound specificity against patient clinical profile. As the number of SGAs increased, this review can assist physicians in the prescription of three novel SGAs already on the market, namely lurasidone, brexpiprazole, cariprazine, and lumateperone, which is in the approval phase for schizophrenia treatment at the FDA. Besides schizophrenia, EMA and/or FDA approved lurasidone for bipolar depression, brexpiprazole as augmentation in major depressive disorder and cariprazine for the acute treatment of manic or mixed episodes associated with bipolar I disorder. These new antipsychotics were developed with the aim of improving efficacy on negative and depressive symptoms and reducing metabolic and cardiovascular side effects compared to prior SGAs, while keeping the risk of extrapyramidal symptoms low. They succeeded quite well in containing these side effects, despite weight gain during acute treatment remains a possible concern for brexpiprazole, while cariprazine and lurasidone show higher risk of akathisia compared to placebo and other SGAs such as olanzapine. The available studies support the expected benefits on negative symptoms, cognitive dysfunction and depressive symptoms, while the overall effect on acute psychotic symptoms may be similar to other SGAs such as quetiapine, aripiprazole and ziprasidone. The discussed new antipsychotics represent useful therapeutic options but their efficacy and side effect profiles should be considered to personalize prescription.
