BACKGROUND: Hyperprolactinemia is commonly seen in patients with schizophrenia on risperidone. Dopamine receptor blockade plays a major role in risperidone induced hyperprolactinemia. However, limited studies are available with inconsistent results on antipsychotic response to risperidone and prolactin elevation. Therefore, we aimed to study the change in serum prolactin levels and response to risperidone and to test the association between DRD2 genetic variants and prolactin levels in schizophrenic patients treated with risperidone...

The aims of this study were to clarify whether atypical antipsychotics can elevate serum levels of both macroprolactin and prolactin, and whether the macroprolactin levels differ according to the type of atypical antipsychotic being taken. In total, 245 subjects were enrolled consecutively in 6 hospitals. Serum prolactin and macroprolactin levels were measured at a single time point during maintenance antipsychotic monotherapy. The mean total serum prolactin levels including macroprolactin were 11.91, 20.73, 16...

INTRODUCTION: Aripiprazole, an atypical or second-generation antipsychotic, is usually well tolerated. It is an approved treatment for schizophrenia and mania in bipolar disorder type 1. Unlike the other antipsychotics, it has high affinity agonist properties for dopamine D2 and D3 receptors. It has also 5-HT1A partial agonist and 5-HT2A antagonist properties. Aripiprazole is a first or second line treatment frequently used because it has reduced side effects such as weight gain, sleepiness, dyslipidemia, insulin resistance, hyperprolactinemia and extrapyramidal symptoms...

This study investigated the effects of a low-dose aripiprazole adjunctive treatment for risperidone- or paliperidone-induced hyperprolactinemia in Han Chinese women with schizophrenia. After 4 weeks of risperidone or paliperidone treatment, 60 out of 66 patients improved significantly and experienced hyperprolactinemia. They were randomly assigned to the treatment group (aripiprazole adjunctive treatment) (n=30) or control group (non-adjunctive treatment) (n=30). The dosage of risperidone and paliperidone were maintained; and aripiprazole was maintained at 5mg/day during the 8-week study period...

BACKGROUND: Iron deficiency disrupts dopaminergic signaling in rodents, resulting in cognitive deficits that may be reversed with psychostimulants. In humans, iron deficiency with or without anemia has similarly been found to cause neuropsychological and behavioral impairments. However, the clinical effects of low body iron stores in antipsychotic-treated children have not been examined. METHODS: Medically healthy, 5- to 17-year-old boys treated with risperidone for at least 1 year were enrolled between February 2009 and November 2013 in a multiphase study, examining the skeletal effects of calcium and vitamin D supplementation in risperidone-induced hyperprolactinemia...

OBJECTIVE: The aim of the study was to identify the impact of pharmacogenetic markers associated with prolactin concentration in risperidone-treated children and adolescents with autism spectrum disorders. METHODS: One hundred forty-seven children and adolescents with autism, aged 3 to 19 years, received risperidone. The clinical data of patients were recorded from medical records. Prolactin levels were measured by chemiluminescence immunoassay. Three CYP2D6 single nucleotide polymorphisms, CYP2D6*4 (1846G>A), *10 (100C>T), and *41 (2988G>A), 1 gene deletion (*5), and DRD2 Taq1A (rs1800497) polymorphism were genotyped by TaqMan real-time polymerase chain reaction...

OBJECTIVE: In children and adolescents treated with risperidone, hyperprolactinemia is a frequent complication that may have clinical repercussions. Several genes have been associated with this occurrence. The aim of this study was to evaluate the frequency of hyperprolactinemia in children and adolescents treated with risperidone, and its associations with clinical and pharmacological data and certain polymorphisms of the following genes: Dopamine receptor D2 (DRD2), 5-hydroxytryptamine (serotonin) receptor 2C (HTR2C), cytochrome P450, family 2, subfamily D, polypeptide 6 (CYP2D6), leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), and scavenger receptor class B, member 2 (SCARB2)...

Estrogens role in schizophrenia patients is a subject, which has gained an increased attention from the medical community. Estrogens have been shown to inhibit dopamine actions, improve neuronal regeneration, and overall, have a protective role in the pathology of schizophrenia. The adjunctive estrogen therapy for men is currently under debate. Antipsychotic medication is known to influence the hypothalamo-hypophyseal - gonadal axis by inducing variable degrees of hyperprolactinemia. Several studies have found that some of the atypical antipsychotics lower cortisol levels in patients and also in healthy controls...

UNLABELLED: A previously healthy 32-year-old woman developed cyclical mood swings after being prescribed cabergoline for a pituitary microprolactinoma. These mood swings persisted for over 2 years, at which point she developed an acute manic episode with psychotic features and was admitted to a psychiatry unit. Cabergoline was discontinued and replaced with aripiprazole 10 mg/day. Her manic episode quickly resolved, and she was discharged within 6 days of admission. The aripiprazole suppressed her prolactin levels for over 18 months of follow-up, even after the dose was lowered to 2 mg/day...

In our previous study, a prolactin elevation was more frequently in risperidone than in blonanserin; however, it was more often in blonanserin than in olanzapine. Therefore, while a rate of PRL rising is low to moderate, hyperprolactinemia is a considerable adverse effect in the blonanserin treatment. In this study, to examine detailed characteristics of hyperprolactinemia of blonanserin, we analyzed the prolactin data in six schizophrenic patients who were switched to blonanserin from other antipsychotics and followed for one year...

OBJECTIVE: The present study aimed to evaluate the efficacy and safety of adjunctive aripiprazole treatment in schizophrenia patients with risperidone-induced hyperprolactinemia. METHODS: One hundred and thirteen patients who were receiving a stable dose of risperidone were randomly assigned to either adjunctive aripiprazole treatment (10 mg/day) (aripiprazole group) or no additional treatment (control group) at a 1:1 ratio for 8 weeks. Schizophrenia symptoms were measured using the Positive and Negative Syndrome Scale (PANSS)...

Hyperprolactinemia is an unwanted adverse effect associated with several antipsychotics. The addition of partial dopamine receptor agonist aripiprazole may attenuate antipsychotic-induced hyperprolactinemia effectively. However, the ideal dosing regimen for this purpose is unknown. We aimed to evaluate the dose effects of adjunctive treatment with aripiprazole on prolactin levels and hyperprolactinemia in schizophrenia patients. Stable subjects 18-45 years old with schizophrenia and hyperprolactinemia (i.e...

BACKGROUND: Antipsychotics have been used for more than 50 years in the treatment of schizophrenia and many other psychiatric disorders. Prolactin levels usually increase in patients treated with risperidone. Aripiprazole, which has a unique effect as an antipsychotic, is a D2 receptor partial agonist. It is an atypical antipsychotic with limited extrapyramidal symptoms. Since it acts as an antagonist in hyperdopaminergic conditions and as an agonist in hypodopaminergic conditions, it does not have adverse effects on serum prolactin levels...

PURPOSE: This article describes the physiology and mechanisms of prolactin and the assessment and clinical management strategies of antipsychotic-induced hyperprolactinemia. CONCLUSIONS: Hyperprolactinemia is a disorder of the hypothalamic-pituitary axis which can be caused by several mechanisms. Typical antipsychotic agents are more likely to cause hyperprolactinemia than atypical antipsychotic agents, with the exception of amisulpride, paliperidone, and risperidone...

The aim of this prospective observational study was to investigate the variations of serum prolactin hormone (PRL) in a sample of 34 drug-naive patients (mean age 13 years) who started risperidone therapy assuming that several factors may favor the increase in serum PRL. Serum PRL and hyperprolactinemia clinical signs were examined at baseline (T0) and after almost 3 months of treatment (T1). We considered sex, pubertal status, risperidone dosage, psychiatric diagnosis, and any personal/family history of autoimmune diseases...
