Long-Acting Injectable Antipsychotics in Adolescents: From Current Evidence and Gaps to Clinical Practice. (PubMed, Pharmaceuticals (Basel)) - "The evidence was organized by drug class: risperidone, paliperidone, aripiprazole, and other antipsychotics (olanzapine, haloperidol, first-generation depots)...Aripiprazole LAI showed functional gains, short-term tolerability, and encouraging acceptance in case reports...When SUD co-occurs, LAIs may also help mitigate risks related to misuse/diversion of oral medication, provided that care includes systematic SUD screening and early intervention. Prospective controlled studies are urgently needed to establish long-term efficacy and safety in this vulnerable population."

Discerning identity: clinical challenges in differentiating gender-themed psychotic symptoms from gender dysphoria- a case report (ECNP 2025) - "Initial treatment included haloperidol (10 mg/day) and risperidone (4 mg/day)...Upon discharge, the patient was prescribed olanzapine 20 mg/day and intramuscular long-acting aripiprazole 400 mg monthly...This diagnostic overlap poses substantial challenges, as clinicians must differentiate between a primary psychotic process with gender-themed delusions and a genuine gender identity disorder coexisting with psychosis. Accurate diagnosis is further complicated by the presence of poor insight, affective instability, and complex auditory hallucinations, all of which may obscure the patient's baseline identity and lived experience."

Comparison of functionality in patients treated with aripiprazole lai versus paliperidone LAI (ECNP 2025) - "The results suggest that patients treated with Aripiprazole LAI exhibit better overall functioning, as measured by the PSP Scale, compared to those treated with Paliperidone LAI. This may be due to differences in the side effect profiles of the two medications. Aripiprazole LAI, being a third-generation antipsychotic, may have fewer sedative and metabolic side effects than Paliperidone LAI, a second-generation antipsychotic."

Clinical effectiveness and safety in psychosis with comorbid pulmonary thromboembolism treated with long-acting injectable Aripiprazole every two months (ECNP 2025) - "A recent meta-analysis concluded that both first- and second-generation antipsychotics significantly increase the risk of VTE and pulmonary embolism (PE), with olanzapine, clozapine, haloperidol, perphenazine, and risperidone showing the highest association [1]...The patient also accepted anticoagulant therapy with dabigatran 150 mg...Conclusions Antipsychotics, particularly olanzapine, may raise the risk of serious thromboembolic events even in young patients without clear risk factors. Aripiprazole, both oral and LAI, is a safe, effective alternative in patients with VTE history, enabling ongoing antipsychotic treatment without compromising vascular safety."

Management of breakthrough psychosis on antipsychotic maintenance medication in a patient treated with long-acting injectable antipsychotic (ECNP 2025) - "The patient was treated with several oral antipsychotics, including amisulpride, olanzapine and aripiprazole. He began treatment with aripiprazole once-monthly 400 mg (AOM 400) after the last discharge in 2019...Conclusions The BAMM phenomenon has also been reported in relation to other long-acting injectable antipsychotics, such as Risperidone or Paliperidone, however, the available data is limited compared to those for aripiprazole [3,4]. This phenomenon reveals that, in some treatment-adherent patients, psychotic symptoms may resurface, especially in stressful situations. Close monitoring and identification of potential causal factors are key to optimizing long-term treatment outcomes."

Shifting the paradigm: the use of long-acting atypical antipsychotics in acute care (ECNP 2025) - "There is one study evaluating the use of aripiprazole once-monthly (AOM) versus placebo in acute inpatients [1]. Loading strategies have since been developed for AOM [2], and aripiprazole two-monthly (ATM) with two simultaneous injections and single oral dose, which have been shown to achieve therapeutic plasma levels within 24 hours. The two loading deltoid doses of 150 and 100 mg paliperidone palmitate once-monthly (PP1M) can be completed within 4 days, and oral supplementation is not required [3]... The pharmacokinetics of atypical LAIs and new loading strategies with the rapid achievement of therapeutic plasma levels suggest the potential consideration of earlier initiation in a variety of acute care settings. Further research is recommended to evaluate safe and effective protocols for early initiation of LAIs which may improve the care pathways of hospital and community management of schizophrenia. Guidelines should be developed or updated to incorporate the most..."

Systemic inflammation and metabolic effects of oral versus long-acting injectable antipsychotics in schizophrenia: a systematic review protocol and preliminary data (ECNP 2025) - "Some studies comparing oral and LAI formulations of olanzapine found no significant differences in weight, BMI, glucose levels, or lipid profiles. Similarly, pooled analyses of oral versus LAI aripiprazole and paliperidone did not reveal significant differences in BMI or cholesterol...This systematic review aims to clarify whether the route of administration plays an independent role in contributing to metabolic or inflammatory burden in patients with SCH or SSD. Results may support more personalized pharmacological strategies with the focus at reducing long-term physical health risks in this population."

Early-onset tardive akathisia following long-acting aripiprazole treatment: successful management with mirtazapine (ECNP 2025) - "Our patient achieved near-full remission of akathisia only after mirtazapine was increased to 30 mg/day,following nonresponse to propranolol, biperiden, clonazepam, and hydroxyzine. Given the 2.5-month gap since the last injection, the remission may be partly due to LAI cessation rather than solely to mirtazapine, although spontaneous remission of tardive akathisia is rare.Although prior studies support the effectiveness of low-dose mirtazapine (15 mg/day) in treating antipsychotic-induced akathisia, our case suggests that higher doses may be required in tardive or refractory presentations[4].Moreover, our case contributes to the limited but growing literature implicating LAI aripiprazole in severe akathisia, even among patients who previously tolerated the oral form[5]. These findings underscore the importance of recognizing early-onset tardive akathisia and considering mirtazapine dose escalation as a second-line strategy when conventional treatments fail."

Use of high doses of second-generation long-acting antipsychotics in patients with resistant schizophrenia. Treatment compliance, effectiveness, and tolerability (ECNP 2025) - "Methods A 72-month observational, mirror-image study of patients with severe (Clinical Global Impression-Severity, CGI-S ≥ 5) resistant schizophrenia receiving treatment with ≥75 mg of risperidone long-acting injectable (RLAI) (N = 60), ≥175 mg of monthly paliperidone palmitate (PP) (N = 60), and ≥600 mg of aripiprazole once-monthly (AOM) (N = 30). These SGA LAI treatments improved treatment adherence and outcomes (hospitalizations, suicide attempts, clinical severity, disability) of the patients, with good tolerability, helping them to achieve clinical stabilization and better functioning. Therefore, we suggest that, in some illness-critical conditions, high doses of SGA LAIs could represent an alternative to clozapine, to date the only therapy for resistant schizophrenia"

Predictive factors for therapeutic change in long-acting injectable antipsychotics: a real-world clinical study (ECNP 2025) - "The data extracted included gender, age, primary diagnosis according to ICD-10, type of initial LAI (aripiprazole, paliperidone, or other), and whether a therapeutic change (switching LAI or discontinuation) was required during the observation period. These results underscore the importance of individualized LAI selection based on diagnostic profile to optimize adherence and minimize the need for subsequent treatment modifications in routine clinical practice. Future prospective studies are warranted to confirm these findings and further refine personalized treatment strategies for this population."

Effectiveness of transcranial magnetic stimulation in negative symptoms of schizophrenia – a case report (ECNP 2025) - " We present the case of a 21-year-old male, hospitalized in the resistant schizophrenia unit and medicated with 300mg of aripiprazole long-acting injection, 500mg of clozapine, and 25mg of fluvoxamine. Studies indicate that high-frequency transcranial magnetic stimulation, targeting the left dorsolateral prefrontal cortex, is safe, well-tolerated, and may be associated with a reduction in the severity of negative symptoms of schizophrenia. These findings are encouraging, considering the limited treatment options currently available for these debilitating symptoms. However, further large-scale research is needed to determine the efficacy more robustly and establish optimal treatment parameters."
