RESUMO

Treatment with long-acting injection (LAI) antipsychotics, such as paliperidone palmitate, has improved the quality of life in terms of symptoms and prevention of relapses in patients with schizophrenia. Although there are plenty of evidences about the efficacy and safety of paliperidone palmitate 3-monthly injection (PP3M) in adults with schizophrenia, literature appears lacking about the use of LAIs during pregnancy. We hereby describe the clinical case of a pregnant woman affected by schizophrenia (DSM-5-TR), taking pharmacological treatment of PP3M. Considering the inadequate evidence regarding the use of PP3M in pregnancy in agreement with the patient, we switched PP3M to an oral therapy with aripiprazole. The switch to oral aripiprazole allowed the patient to improve her sense of autonomy and strengthen the therapeutic relationship. To our knowledge, this is the first case report monitoring an entire pregnancy of a women affected by schizophrenia in treatment with PP3M injection and oral aripiprazole. No obstetrical or fetal complications were reported. As the research in this field is very demanding, it would be precipitous to derive final conclusions from the current case report, but we hope to build a growing number of data that would allow us to make more appropriate and safe therapeutic choices in such a vulnerable phase as the peripartum.

RESUMO

INTRODUCTION: Non-adherence to medication significantly affects bipolar disorder outcomes. Long-Acting Injectable antipsychotics show promise by ensuring adherence and averting relapses. AREAS COVERED: This narrative review sought to evaluate the efficacy of second-generation injectable antipsychotics in bipolar disorder through searches in Embase, MEDLINE, and PsycInfo for randomized controlled trials and mirror-image studies.Risperidone and aripiprazole Long-Acting Injectables demonstrated effectiveness in preventing mood recurrences compared to placebos in adults with bipolar disorder. They showed superiority in preventing mania/hypomania relapses over placebos but did not appear to significantly outperform active oral controls. Notably, active controls seem to be more effective in preventing depression relapses than Long-Acting Injectables. Mirror-Image studies point toward the reduction of hospitalization rates following LAI initiation. EXPERT OPINION: The available evidence points thus toward the efficacy of LAIs, especially in managing manic episodes and reducing hospitalizations, The current evidence does not however immediately support prioritizing LAIs over oral medications in bipolar disorder treatment. More high-quality studies, especially comparing LAIs directly with active controls, are crucial to gain a comprehensive understanding of their efficacy. These findings highlight the need for further research to guide clinicians in optimizing treatment strategies for bipolar disorder.

RESUMO

It has been previously reported that among patients with schizophrenia that long-acting injectable (LAI) antipsychotic formulations can delay time to relapse longer when compared to their oral equivalents when patients discontinue therapy. Unanswered is whether this same pattern would be observed for patients with bipolar disorder receiving maintenance treatment. A systematic review was undertaken to identify relevant studies of LAI antipsychotics in maintenance treatment of bipolar disorder, employing a placebo-controlled randomized withdrawal design, and where equivalent studies using the corresponding oral formulation were also available. We found five studies [one aripiprazole monohydrate once monthly (AOM) study, one oral aripiprazole (OARI) study, two 2 weeks risperidone-LAI (RIS-LAI) studies, and one oral paliperidone (OPAL) study]. Numerically lower recurrence rates at 2, 4, 6, 8, 12, 16, 20, and 26 weeks were observed when AOM was discontinued when compared with discontinuation from OARI. Numerically lower recurrence rates at 2, 4, 6, 8, and 16 weeks were observed when RIS-LAI was discontinued when compared with discontinuation from OPAL. These results can be interpreted as a substantial delay in time to recurrence with a LAI antipsychotics formulation compared to the oral equivalent when medication is discontinued in patients with mania who had been stabilized on LAI antipsychotics or corresponding oral antipsychotics.

RESUMO

BACKGROUND: Aripiprazole augmentation is proven effective for antidepressant-refractory depression, but its licensed dose range is wide and optimal dosage remains unclear. AIMS: To find the optimal dosage of aripiprazole augmentation. METHOD: Multiple electronic databases were searched (from inception to 16 February 2021) to identify all assessor-masked randomised controlled trials evaluating aripiprazole augmentation therapy in adults (≥18 years old, both genders) with major depressive disorder showing inadequate response to at least one antidepressant treatment. A random-effects, one-stage dose-effect meta-analysis with restricted cubic splines was conducted. Outcomes were efficacy (treatment response: ≥50% reduction in depression severity), tolerability (drop-out due to adverse effects) and acceptability (drop-out for any reason) after 8 weeks of treatment (range 4-12 weeks). RESULTS: Ten studies met the inclusion criteria. All were individually randomised, placebo-controlled, multi-centre, parallel studies including 2625 participants in total. The maximum target dose-efficacy curve showed an increase up to doses between 2 mg (odds ratio OR = 1.46, 95% CI 1.15-1.85) and 5 mg (OR = 1.93, 95% CI 1.33-2.81), and then a non-increasing trend through the higher licensed doses up to 20 mg (OR = 1.90, 95% CI 1.52-2.37). Tolerability showed a similar trend with greater uncertainty. Acceptability showed no significant difference through the examined dose range. Certainty of evidence was low to moderate. CONCLUSIONS: Low-dose aripiprazole as augmentation treatment might achieve the optimal balance between efficacy, tolerability and acceptability in the acute treatment of antidepressant-refractory depression. However, the small number of included studies and the overall moderate to high risk of bias seriously compromise the reliability of the results. Further research is required to investigate the benefits of low versus high dose.

RESUMO

BACKGROUND: Although long-acting injectable antipsychotics (LAI-APs) have been considered as a monotherapeutic option in the maintenance treatment of schizophrenia, it has been recently reported that the combination therapy of LAI-APs and oral antipsychotics (OAPs) is common. METHODS: We conducted a retrospective chart review to examine the situation of the combination therapy of LAI second-generation antipsychotics (LAI-SGAs) and OAPs, and a questionnaire survey to investigate prescribers' attitudes toward the combination therapy. We included patients who received any LAI-SGAs for 1 month or longer and classified them into monotherapy and combination therapy groups. We collected information on age, sex, primary psychiatric diagnosis, and concomitant psychotropic medications. RESULTS: Of the 132 patients, 39 (29.5%) received the combination therapy of LAI-SGAs and OAPs. Long-acting injectable risperidone was significantly associated with receiving the combination therapy compared with LAI aripiprazole. Olanzapine was the most common OAP in combination with LAI-SGAs. Only 8 patients (20.5%) concurrently received the same type of OAPs as LAI-SGAs. More than 60% of the patients received OAP polypharmacy before the initiation of LAI-SGAs. The psychiatrists in charge prescribed LAI-SGAs mainly because of a concern about adherence, and OAPs mainly because of insufficient dose of LAI-SGAs, to patients in the combination therapy group. They estimated that adherence to OAPs in two thirds of the patients in the combination therapy group was 80% or higher. CONCLUSIONS: The present study showed that the combination therapy of LAI-SGAs and OAPs is often conducted in real-world clinical practice. Considering the reason for the introduction of LAI-APs, clinicians should carefully monitor patients' adherence to OAPs concurrently used with LAI-APs.

RESUMO

PURPOSE/BACKGROUND: The aim of this study was to examine the association between genetically predicted CYP2D6 phenotypes and extrapyramidal symptoms (EPSs). METHODS/PROCEDURES: Data from the Tolerability and Efficacy of Antipsychotics trial of adolescents with first-episode psychosis randomized to aripiprazole versus quetiapine extended release were studied. Extrapyramidal symptom assessments included the Simpson-Angus Scale and the Barnes Akathisia Rating Scale. Patients were CYP2D6 genotyped. Plasma concentrations of antipsychotics and antidepressants were analyzed. FINDINGS/RESULTS: One hundred thirteen youths (age, 12-17 years; males, 30%; antipsychotic naive, 51%) were enrolled. Poor metabolizers had a significantly higher dose-adjusted aripiprazole plasma concentration (±SD) compared with normal metabolizers at week 4 (24.30 ± 6.40 ng/mL per milligram vs 14.85 ± 6.15 ng/mL per milligram; P = 0.019), but not at week 12 (22.15 ± 11.04 ng/mL per milligram vs 14.32 ± 4.52 ng/mL per milligram; P = 0.067). This association was not found in the quetiapine extended release group. No association between CYP2D6 genotype groups and global Barnes Akathisia Rating Scale score or Simpson-Angus Scale score was found in any of the treatment arms. IMPLICATIONS/CONCLUSIONS: Our results do not support routine use of CYP2D6 testing as a predictor of drug-induced parkinsonism or akathisia risk in clinical settings. Further studies with larger samples of CYP2D6 poor metabolizers are needed.

RESUMO

BACKGROUND: Continuous antipsychotic therapy is recommended as part of long-term maintenance treatment of schizophrenia, and gaps in antipsychotic treatment have been associated with increased risks of relapse and rehospitalization. Because the use of long-acting injectable (LAI) antipsychotics may reduce the likelihood of undetected medication gaps, initiating an LAI medication may affect resource utilization and costs. The LAI aripiprazole lauroxil (AL) was approved in the United States (US) in 2015 for the treatment of schizophrenia in adults. OBJECTIVE: The objective of this retrospective observational cohort study was to examine treatment patterns, resource utilization, and costs following initiation of AL for the treatment of schizophrenia in adults. METHODS: A retrospective analysis of Medicaid claims data identified a cohort of patients (N = 485) starting AL shortly after Food and Drug Administration approval in October 2015. Treatment patterns, resource utilization, and costs were compared 6 months before and after treatment initiation. Subgroup analyses were conducted based on the type of antipsychotic (LAI, oral, or none) received before initiation of AL. RESULTS: Over 6 months of follow-up, patients received an average of 4.6 injections out of a maximum of six (77%). After initiating AL, all-cause inpatient admissions decreased by 22.4%; other significant reductions were observed in mental health-related admissions and emergency room (ER) visits. All-cause inpatient costs decreased by an average of US$2836 per patient (p < 0.05) in the 6-month post-AL period, whereas outpatient pharmacy costs increased by US$4121 (p < 0.05), resulting in no significant difference in overall costs between the pre- and post-AL periods. The subgroup of patients who had been prescribed an oral antipsychotic before starting AL had significant reductions in proportion of patients with inpatient and ER visits and costs, but also reported a significant increase in pharmacy costs. CONCLUSIONS: AL was associated with a significant reduction in inpatient costs and an increase in outpatient pharmacy costs, resulting in no changes in total healthcare costs over 6 months. The adherence rate and reductions in inpatient use may indicate the potential for greater clinical stability among patients initiated on AL compared with their previous treatment.

RESUMO

PURPOSE/BACKGROUND: Frontal and temporal cerebral blood flow (CBF) changes are the most common impairments of CBF described in patients with schizophrenia. Those impairments have also been associated with cognitive deficits, a hallmark of schizophrenia. In light of that fact, treatment interventions should target cognitive deficits to prevent chronic disability. However, specific therapies targeting cognitive symptoms are very few and far between. One of the treatment possibilities is aripiprazole, because several studies reported its potential procognitive effects. The objective of this study was to investigate whether use of aripiprazole in its long-acting injectable formulation (ALAI), during a 3-month treatment, has beneficial effects on CBF and cognitive functioning in patients with first episode of schizophrenia. METHODS/PROCEDURES: Single-photon emission computed tomography with technetium-99m hexamethylpropylene amine oxime was performed at 2 time points. Cognitive functions were assessed with a standardized test for cognitive functions, 5-KOG test, whereas severity of clinical symptoms was assessed with the Positive and Negative Syndrome Scale, both at the same 2 time points as single-photon emission computed tomography. Three-month treatment with ALAI was associated with improvement of several cognition indices and improvements of right-sided frontal and temporal CBF, as well as of clinical symptoms. FINDINGS/RESULTS: Multivariate tests were used to test for the effects of ALAI treatment on cognitive functions, clinical presentation, and brain perfusion in a 3-month period. Multivariate model revealed statistical significance (F = 11.958, P < 0.001). Of 10 separate 5-KOG parameters, 3-month treatment with ALAI significantly influenced 4: undelayed recall, delayed recall, attention, and working memory-digit span forward. Finally, 3-month ALAI treatment significantly improved regional CBF in 2 of 4 investigated areas, both on the right side of the brain (frontally and temporally). IMPLICATIONS/CONCLUSIONS: Results of this research showed that treatment with ALAI in patients with first episode of schizophrenia is associated with improved right-sided frontal and temporal CBF, as well as with improved symptoms, including cognition indices. Although we cannot confirm it directly, it is possible that improved frontotemporal CBF led to the improvement in cognition indices.

RESUMO

BACKGROUND: Preclinical and clinical studies have indicated that impaired endogenous synthesis of glutathione during early postnatal development plays a significant role in the pathophysiology of schizophrenia. Moreover, some studies have suggested that antidepressants are able to increase the activity of atypical antipsychotics which may efficiently improve the treatment of negative and cognitive symptoms of schizophrenia. METHODS: In the present study, we investigated the influence of repeated co-treatment with escitalopram and aripiprazole on the schizophrenia-like behavior and BDNF mRNA expression in adult rats exposed to glutathione deficit during early postnatal development. Male pups between the postnatal days p5-p16 were treated with the inhibitor of glutathione synthesis, BSO (L-buthionine-(S,R)-sulfoximine) and the dopamine uptake inhibitor, GBR 12,909 alone or in combination. Escitalopram and aripiprazole were given repeatedly for 21 days before the tests. On p90-92 rats were evaluated in the behavioral and biochemical tests. RESULTS: BSO given alone and together with GBR 12,909 induced deficits in the studied behavioral tests and decreased the expression of BDNF mRNA. Repeated aripiprazole administration at a higher dose reversed these behavioral deficits. Co-treatment with aripiprazole and an ineffective dose of escitalopram also abolished the behavioral deficits in the studied tests. CONCLUSION: The obtained data indicated that the inhibition of glutathione synthesis in early postnatal development induced long-term deficits corresponding to schizophrenia-like behavior and decreased the BDNF mRNA expression in adult rats, and these behavioral deficits were reversed by repeated treatment with a higher dose of aripiprazole and also by co-treatment with aripiprazole and ineffective dose of escitalopram.

RESUMO

In the current study, a composite in-situ gel formulation containing aripiprazole (APZ) loaded transfersomes (TFS) was developed for the intranasal brain targeting of APZ. APZ loaded TFS were prepared by applying the film hydration method and optimized using an irregular factorial design. The prepared formulations were optimized based on different parameters including particle size, polydispersity index (PdI), zeta potential, encapsulation efficiency (EE) and release efficiency (RE). The optimized APZ-TFS were distributed in an ion-triggered deacetylated gellan gum solution (APZ-TFS-Gel) and evaluated in terms of pH, gelling time, rheological properties and in-vitro release study. The therapeutic efficacy of the best APZ-TFS-Gel was then tested in the mice model of schizophrenia induced by ketamine by evaluating various behavioral parameters. The optimized formulation showed the particle size of 72.12 ± 0.72 nm, the PdI of 0.19 ± 0.07, the zeta potential of -55.56 ± 1.9 mV, the EE of 97.06 ± 0.10%, and the RE of 70.84 ± 1.54%. The in-vivo results showed that compared with the other treatment groups, there was a considerable increase in swimming and climbing time and a decrease in locomotors activity and immobility time in the group receiving APZ-TFS-Gel. Thus, APZ-TFS-Gel was found to have desirable characteristics for therapeutic improvement.

RESUMO

ABSTRACT: Acute dystonic reactions are a worrying reason for presentation to the pediatric emergency department and the pediatric neurology clinic in childhood. It must be diagnosed and treated quickly. The aim of this study was to examine the clinical presentations, etiological factors, and prognosis of patients presenting to our regional tertiary pediatric neurology clinic with a diagnosis of acute dystonic reactions in children.Nine pediatric patients who were treated for acute dystonic reactions between May, 2018 and May, 2020 and had adequate follow-up were included in the study. Medical record data were reviewed age, gender, etiology, features of family, treatment, and results.Three of the patients were female and 6 were male. Their average age was 11 years (4-17). All patients were evaluated as a drug-induced acute dystonic reaction. Of the 9 patients, 5 were due to metoclopramide, 3 were due to risperidone, and 1 was due to aripiprazole. It was learned that a similar situation against other drugs developed in the family history of 3 patients. As a treatment, all of them were intramuscularly applied biperiden suitable for their weight and 30 minutes dramatic improvement was observed. Additional dose had to be administered in only 1 case. All cases were discharged for 24 hours. No problem was observed in their follow-up.Drug-induced acute dystonic reaction can be diagnosed and has a clinical picture that completely resolves when effective treatment is applied. However, it should not be forgotten that it can reach life-threatening dimensions clinically.

RESUMO

To assess the bioequivalence of 2 formulations of aripiprazole orally disintegrating tablets and to monitor their safety and tolerability in Chinese subjects, a single-site, open-label, randomized, 2-preparation, single-dose, 2-period crossover design was conducted. All 60 subjects were randomly divided into the fasting group and the fed group. Blood samples were collected at scheduled times after a single oral dose of orodispersible tablets containing 10 mg of aripiprazole. In the fasting state, the geometric mean ratios (90% confidence intervals [CIs]) of the test/reference formulation were 92.22%-100.20% for the area under the concentration-time curve (AUC) from time zero to the last measured concentration (AUC0-t ), 91.73%-100.14% for the AUC from administration to infinite time (AUC0-∞ ), and 98.52%-112.52% for the maximum plasma concentration (Cmax ). In the fed state, AUC0-t , AUC0-∞ , and Cmax were 92.23%-100.20%, 91.73%-100.14%, and 95.91%-105.13%, respectively. The 90%CIs of the test/reference AUC ratio and Cmax ratio were within the acceptance range of 80.00%-125.00% for bioequivalence. Neither the maximum peak plasma concentration (tmax ) nor the terminal elimination half-life (t1/2 ) showed any significant difference. No serious adverse events) were encountered during the study. The test and reference formulations were bioequivalent under both fasting and fed conditions and were found to be safe and tolerated.

RESUMO

PURPOSE/BACKGROUND: This study aimed to explore the discontinuation rate of aripiprazole long-acting injection (LAI) in a naturalistic clinical setting. METHODS/PROCEDURES: A retrospective cohort study of 1 year duration was conducted on the first 200 patients registered to receive aripiprazole LAI in Sussex, UK. Rate of discontinuation and the association of robustly recorded clinical variables with discontinuation or a new acute care episode were explored. FINDINGS/RESULTS: Of 200 registered, 173 patients initiated aripiprazole LAI and 40% discontinued this by 1 year. Mean discontinuation time was 18 weeks. The commonest discontinuation reason was "patient choice," independent of efficacy or adverse effects. Not having a diagnosis of schizophrenia spectrum was the only variable significantly associated with treatment continuation after 1 year. No single diagnostic group accounted for this, although a greater continuation rate was observed in those with bipolar disorder. Illness severity factors at baseline, including apparent treatment resistance, had no impact on later aripiprazole LAI discontinuation or on acute service use over the year. Medication-related variables had no identified impact on acute service use. IMPLICATIONS/CONCLUSIONS: This study supports the clinical utility of aripiprazole LAI for its licensed indications. The 1-year discontinuation rate is equivalent to that in reports of similarly designed studies of paliperidone LAI. Further exploration of nonmedication factors influencing LAI discontinuation is required. Preferential use of aripiprazole LAI over other medications may be supported due to fewer associated metabolic adverse effects.

RESUMO

BACKGROUND: Most studies investigating antipsychotic effectiveness report either total psychopathology or symptom cluster findings. Studies focusing on a separate symptom, such as hallucinations, a hallmark symptom in schizophrenia, are scarce.Therefore, the current study aims to compare the antihallucinatory effectiveness of 3 pharmacologically different antipsychotics: olanzapine, amisulpride, and aripiprazole. METHODS: The present study is part of the Bergen-Stavanger-Innsbruck-Trondheim study, a 12-month prospective, randomized, pragmatic antipsychotic drug trial in active-phase schizophrenia spectrum disorders. The primary outcome of the present study was change of hallucinations as measured by item P3 (hallucinatory behavior) from the Positive and Negative Syndrome Scale in the subgroup with hallucinations at baseline. Primary analyses were intention to treat. RESULTS: A total of 144 participants were included in the study, where 105 (72%) had a score of 3 or more on the Positive and Negative Syndrome Scale P3 item at baseline, indicating the presence of hallucinations (HALL subgroup).In the HALL subgroup, a significantly less reduction of hallucinations was revealed for participants using olanzapine in weeks 12, 26, 39, and 52 when compared with amisulpride and in weeks 26 and 52 when compared with aripiprazole. In subanalyses for participants never exposed to antipsychotic drugs (antipsychotic-naive) and those who had used antipsychotics before entering the study, antihallucinatory differences were revealed only in the latter group. CONCLUSIONS: A differential antihallucinatory effect of the 3 study drugs was present. The inferior effect of olanzapine seems to be driven by the subgroup of participants exposed to antipsychotic treatment before entering the study.

RESUMO

PURPOSE/BACKGROUND: Hippocampal volume loss in early schizophrenia has been linked with markers of inflammation and oxidative stress, and with less response of negative symptoms. Aripiprazole has been reported to preserve hippocampal volume and to reduce inflammation. METHODS/PROCEDURES: Study 1 was a 12-month multicenter randomized placebo-controlled trial of citalopram added to clinician-determined second-generation antipsychotic medication in 95 patients with first-episode schizophrenia (FES), 19 of whom received aripiprazole. We compared participants taking aripiprazole with those on other antipsychotics to determine whether those on aripiprazole had less hippocampal volume loss. We also examined peripheral biomarker data from medication-naive patients with schizophrenia receiving 8 weeks of antipsychotic treatment (n = 24) to see whether markers of inflammation and oxidative stress that previously predicted hippocampal volume differed between aripiprazole (n = 9) and other antipsychotics (study 2). FINDINGS/RESULTS: Aripiprazole was associated with a mean increase in hippocampal volume of 0.35% (SD, 0.80%) compared with a 0.53% decrease (SD, 1.2%) with other antipsychotics during the first year of maintenance treatment in patients with FES. This difference was significant after adjusting for age, sex, citalopram treatment, and baseline Brief Psychiatric Rating Scale score (B = 0.0079, P = 0.03). Aripiprazole was also associated with reduced concentrations of the inflammatory cytokines interleukin-8 and tumor necrosis factor (P < 0.01) during the first 8 weeks of treatment in medication-naive patients with FES. IMPLICATIONS/CONCLUSIONS: These results suggest that aripiprazole may protect against hippocampal atrophy via an anti-inflammatory mechanism, but these results require replication in larger, randomized trials, and the clinical relevance of hippocampal volume loss is not established.

RESUMO

BACKGROUND: Non-response to first-line treatment for major depressive disorder (MDD) is common; for such individuals, quality of life (QoL) impairments can be severe. Identifying predictors of QoL changes may support the management of cases with persistent depressive symptoms despite adequate initial pharmacological/psychological treatment. OBJECTIVE: The present study aimed to explore predictors of domain-specific QoL improvement following adjunctive aripiprazole treatment for inadequate response to initial antidepressant therapy. METHODS: We evaluated secondary QoL outcomes from a CAN-BIND (Canadian Biomarker Integration Network in Depression) study in patients with MDD who did not respond to an initial 8 weeks of escitalopram and received a further 8 weeks of adjunctive aripiprazole (n = 96). Physical, psychological, social, and environmental QoL domains were assessed using the World Health Organization QoL Scale Brief Version (WHOQOL-BREF). Clinician-rated depressive symptoms were assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS). Functioning was measured with the Sheehan Disability Scale (SDS). Satisfaction with medication was assessed with a single item from the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF). Exploratory t-tests were used to describe domain score changes. A hierarchical linear regression was used to explore demographic, clinical, and treatment-related predictors of improvement. RESULTS: Across domains, QoL improved with adjunctive aripiprazole treatment. Satisfaction with medication and MADRS and SDS scores similarly improved. Symptom reduction was a predictor for positive change to physical and psychological QoL; functioning improvements were predictive of increases to all QoL domains. Satisfaction with medication predicted improvements to physical and psychological domains, whereas number of medication trials was a predictor of worsening QoL in the physical domain. CONCLUSION: The final model explained the most variance in psychological (68%) and physical (67%) QoL. Less variance was explained for environmental (43%) and social QoL (33%), highlighting a need for further exploration of predictors in these domains. Strategies such as functional remediation may have potential to support QoL for individuals with persistent depressive symptoms. CLINICAL TRIALS REGISTRY: ClinicalTrials.gov identifier: NCT016557.

RESUMO

Psychotropic medication treatment can cause elevated serum prolactin levels and hyperprolactinaemia (HPRL). Reports have suggested that aripiprazole may decrease elevated prolactin. The aim of this review was to assess evidence for the efficacy of adjunct aripiprazole in the treatment of psychotropic-induced HPRL. PubMed and Google Scholar were searched to identify randomised placebo-controlled trials (RCTs) of adjunct aripiprazole in patients with HPRL attributed to primary psychotropic medications. Data for individual patients from case studies, chart reviews and open-label studies were also identified and assessed. Six RCTs, with a total of 609 patients, met inclusion criteria. Primary psychotropics included risperidone, haloperidol, paliperidone, fluphenazine and loxapine. Reductions in prolactin from baseline, before the introduction of aripiprazole, were significantly greater for adjunct aripiprazole than for adjunct placebo in all the studies (p = 0.04 to p < 0.0001). Normalisation of serum prolactin levels was significantly more likely with adjunct aripiprazole than adjunct placebo (p = 0.028 to p < 0.001, data from three studies). Improvement or resolution of HPRL-related symptoms (galactorrhoea, oligomenorrhoea, amenorrhoea and sexual dysfunction) were reported in three studies. Prolactin levels decreased in all case reports and in both of two open-label studies; they normalised in 30/41 patients (73.2%) in case studies and 12/29 (41.4%) in the open-label studies. Adjunct aripiprazole was statistically significantly effective in treating elevated serum prolactin levels in six RCTs. Evidence from case reports and open-label studies suggests a degree of effectiveness in most patients.

RESUMO

Antipsychotics, including amisulpride (AMI), quetiapine (QUE), aripiprazole (ARI), and olanzapine (OLA), are used to treat mental illnesses associated with psychotic symptoms. The effect of these drugs on c-Fos expression in vasopressinergic (AVP) and oxytocinergic (OXY) neurons was studied in the hypothalamic paraventricular nucleus (PVN) of rats. The presence of c-Fos in AVP and OXY perikarya was investigated in seven PVN cells segregations: the anterior (Ant), dorsal cup (Dc), wing-shaped (Wi), periventricular zone (Pe), circle-shaped core (Co) and shell of core (Sh), and the posterior (pPVN) after an acute treatment with AMI-20 mg/kg, QUE-15 mg/kg, ARI-10 mg/kg, and OLA-5 mg/kg/bw in rats. Ninety min after treatments, the animals were sacrificed by transcardial perfusion with fixative and the PVN area sliced into 35 µm thick coronal sections for immunohistochemistry. The c-Fos was processed by avidin-biotin-peroxidase complex intensified with nickel-enhanced 3,3'-diaminobenzidine tetrahydrochloride. Visualization of AVP- and OXY-synthesizing neurons was achieved by a fluorescent marker Alexa Flour 568. The c-Fos-AVP and c-Fos-OXY colocalizations were evaluated from c-Fos stained sections merged with AVP or OXY ones. AMI, QUE, ARI, and OLA, single administration distinctly increased the c-Fos expression in each of the PVN cells segregations. QUE induced the highest magnitude of activation of AVP and OXY neurons, while OLA and AMI had only moderate effects. Incontestable variabilities detected in c-Fos expression in PVN AVP and OXY neurons extend the knowledge of selected antipsychotics extra-striatal actions and may also be helpful in a presumption of their possible functional impact.
