Abstract
Clozapine-induced myocarditis (CIM) is among the most important adverse events limiting the use of clozapine as the most effective treatment for schizophrenia. CIM necessitates the immediate termination of clozapine, often resulting in its permanent discontinuation with considerable detrimental effects on patients' psychopathology and long-term outcome. Consequently, a clozapine re-challenge after CIM is increasingly regarded as a viable alternative, with published reports indicating a success rate of approximately 60%. However, published cases of re-challenges after CIM remain limited. Here, we provide a narrative review of the current state of research regarding the epidemiology, pathophysiology, risk factors, diagnosis and clinical management of CIM as well as a synthesis of current recommendations for re-challenging patients after CIM. This includes a step-by-step guide for this crucial procedure based on the current evidence regarding the pathophysiology and risk factors for CIM. Slow dose titration regimes and addressing risk factors including concomitant valproate and olanzapine are crucial both to prevent CIM and to ensure a safe and successful re-challenge. Furthermore, we discuss the utility of C-reactive protein, troponin, N-terminal-pro hormone and brain natriuretic peptide, therapeutic drug-monitoring and cardiac magnetic resonance imaging for CIM screening and diagnosis as well as for post-CIM re-challenges.

Abstract
INTRODUCTION Effective side effects management present a challenge in antipsychotic treatment with second-generation antipsychotics (SGAs). In recent years, most of the commonly used SGAs, except for clozapine, have been shown to differ only slightly in their effectiveness, but considerably regarding perceived side effects, safety profiles, and compatibility to preexisting medical conditions. AREAS COVERED The current state of available evidence on side-effect management in SGA treatment of patients with schizophrenia spectrum disorders (SSD) is reviewed. In addition, current guideline recommendations are summarized, highlighting evidence gaps. EXPERT OPINION SGA safety and side effects needs to be considered in treatment planning. Shared decision-making assistants (SDMA) can support patients, practitioners and relatives to orient their decisions toward avoiding side effects relevant to patients' adherence. Alongside general measures like psychosocial and psychotherapeutic care, switching to better tolerated SGAs can be considered a relatively safe strategy. By contrast, novel meta-analytical evidence emphasizes that dose reduction of SGAs can statistically increase the risk of relapse and other unfavorable outcomes. Further, depending on the type and severity of SGA-related side effects, specific treatments can be used to alleviate induced side effects (e.g. add-on metformin to reduce weight-gain). Finally, discontinuation should be reserved for acute emergencies.

Abstract
Concomitant pain syndromes and cardiovascular disease (CVD) and disorders are associated with significant morbidity, impaired quality of life, and neuropsychiatric disorders. There is an interplay between the mechanisms of pathophysiology of both CVD and pain syndromes. Patients with CVD (and/or disorders) as well as pain syndromes have an increased propensity for drug-drug/disease interactions. Therefore, an understanding of how to use pharmacotherapy to treat pain syndromes, in the context of patients who have diagnoses of CVD and/or disorders, is paramount to patients' success in achieving adequate pain control and appropriately managing CVD and/or disorders, all while decreasing the risk of adverse events (AEs) both from pharmacotherapy to treat pain and CVD (and/or disorders). Based on the appraisal of literature and authors' clinical expertise, it was determined that gabapentinoids, opioids, skeletal muscle relaxants, tricyclic antidepressants, clonidine, serotonin norepinephrine-reuptake inhibitors, dronabinol, carbamazepine, second-generation antipsychotics, non-steroidal anti-inflammatory drugs, aspirin, corticosteroids, and topical anesthetics have the most evidence for use in patients with CVD and/or disorders. However, the literature surrounding the use of pharmacotherapy for pain management is limited to retrospective studies and there is a lack of well-designed, prospective, randomized trials; this also includes head-to-head comparator studies. Unlike many CVD-related pharmacotherapy studies, data studying pain management in patients with CVD lacks standardized outcomes that are consistent among the pool of data. Overall, the decision to prescribe specific pain management therapies in patients with CVD and/or disorders should include assessment of pain severity, type of pain, drug-drug/disease interactions, adjuvant therapies required, and the risk or presence of AEs.

When to Use Amisulpride in Adolescents: A Retrospective Chart Examination of Inpatients. J Clin Psychopharmacol 2022; 42:247-253.

Abstract
PURPOSE/BACKGROUND Despite increasing interest in amisulpride, current knowledge about its use in the pediatric population is scarce. This chart review aimed to investigate the use of amisulpride in a naturalistic adolescent population. METHODS/PROCEDURES Electronic medical records of a tertiary care adolescent inpatient unit were screened between January 2015 and April 2021. Sociodemographic data and all clinical information were collected via data collection forms, and targeted symptoms were obtained from patients' files. Patients with early-onset psychotic disorders (n = 58), bipolar I disorder (n = 29), major depressive disorder (n = 14), and other psychiatric diagnoses (n = 9) were included. Treatment response was defined as a Clinical Global Impression-Improvement of at least much improvement after treatment. FINDINGS/RESULTS Median titration rate of amisulpride was 400 mg/wk, and the maximum administered daily dose ranged between 100 and 1200 mg/d. The maximum daily dose and number of previous antipsychotics were higher in the early-onset psychotic disorder group. Persistent positive symptoms and resistance to previous treatments were leading causes for amisulpride treatment. Other indications were also impulsive/disruptive behaviors, antipsychotic adverse effects, depressive symptoms, somatic complaints, and abnormalities in liver function tests. Finally, patients with lower daily treatment doses and more previous antipsychotic trials are less likely to benefit from the treatment. IMPLICATIONS/CONCLUSIONS Persistent psychotic/mood symptoms, impulsive/disruptive behaviors, and abnormalities in liver function tests were reasons for the amisulpride treatment in adolescents. Randomized placebo-controlled trials are needed to evaluate the efficacy and safety of the treatment in adolescents.

Abstract
Clozapine is an atypical antipsychotic recommended for patients with treatment-resistant schizophrenia whose illness has not responded adequately to treatment despite the sequential use of at least two different antipsychotic drugs at therapeutic doses. Unfortunately, clozapine is frequently discontinued due to both real and perceived serious, and potentially life-threatening, adverse effects, contributing to the underutilisation of the most effective treatment in refractory psychotic disorders. Here, we present the case of a 51-year-old man with treatment-resistant schizoaffective disorder, who was admitted to a locked rehabilitation unit for a clozapine rechallenge. Within 6 months after the clozapine rechallenge, he was diagnosed with heart failure likely secondary to his antipsychotic treatment. Clozapine-induced heart failure usually prompts immediate cessation of treatment. However, in this case, clozapine was continued with cardiology consultation. Ramipril and bisoprolol were initiated and the patient's cardiac condition progressively improved over time. Clozapine-induced heart failure is a serious cardiovascular complication of treatment, usually resulting in discontinuation of treatment. Although there are cases of successful rechallenge, temporary cessation of treatment can lead to severe psychotic exacerbation and non-engagement with cardiac specialists. More evidence is required for continued use of clozapine in a patient with clozapine-induced cardiac complications.
