Antipsychotic Medications and Weight Gain: Etiologies, Predictors and Adverse Clinical Consequences (original) (raw)

The Complex Relationship between Antipsychotic-Induced Weight Gain and Therapeutic Benefits: A Systematic Review and Implications for Treatment

Frontiers in neuroscience, 2017

Antipsychotic-induced weight gain (AIWG) and other adverse metabolic effects represent serious side effects faced by many patients with psychosis that can lead to numerous comorbidities and which reduce the lifespan. While the pathophysiology of AIWG remains poorly understood, numerous studies have reported a positive association between AIWG and the therapeutic benefit of antipsychotic medications. To review the literature to (1) determine if AIWG is consistently associated with therapeutic benefit and (2) investigate which variables may mediate such an association. MEDLINE, Google Scholar, Cochrane Database and PsycINFO databases were searched for articles containing all the following exploded MESH terms: schizophrenia [AND] antipsychotic agents/neuroleptics [AND] (weight gain [OR] lipids [OR] insulin [OR] leptin) [AND] treatment outcome. Results were limited to full-text, English journal articles. Our literature search uncovered 31 independent studies which investigated an AIWG-t...

Pharmacological Add-On Treatments in Managing Antipsychotic-Induced Weight Gain

The European Conference of Psychiatry and Mental Health "Galatia"

Introduction: One of the most common antipsychotic (AP) related adverse drug reactions is weight gain, with a large proportion of patients started on AP even from the onset of schizophrenia, ending up gaining considerable weight. Aim: The study was designed to research current evidence for reducing weight gain through pharmacological supplementation or other practical interventions, in patients treated with APs. Method: A review of the published works found on MEDLINE and PubMed from 2015 to 2019 was done, concentrating mostly on research that specifically examined changes in body weight in individuals taking AP medications along with various pharmaceutical supplements. There were 14 major eligible articles found and examined. We have concentrated on many meta-analyses that evaluated various pharmacological classes, including appetite suppressants, anti-obesity medications, anti-diabetics, gastrointestinal medicines, and anticonvulsants, in avoiding or lowering weight gain in patien...

Clinical and Biological Perspectives of Non-antipsychotic Psychotropic Medications and Weight Gain

International Neuropsychiatric Disease Journal

Background: Non-antipsychotic medications are frequently used in psychiatric patients with a variety of disorders. However, there is limited research concerning weight gain and metabolic changes in mentally ill population. Objective: This review aimed to critically describe non-antipsychotic psychotropic (NAP) medications and their impact on weight in the psychiatric population. Also, the biological and psychosocial mechanisms of weight gain or loss attributed to NAP and antipsychotic medications are also described in this paper. Methods: Electronic searches (2000-2018) of PubMed, Medline,

Antipsychotic-induced weight gain in first-episode psychosis patients: a meta-analysis of differential effects of antipsychotic medications

Early Intervention in Psychiatry, 2015

Aim-The first-episode psychosis (FEP) represents a critical period to prevent cardiovascular and metabolic morbidity decades later. Antipsychotic (AP)-induced weight gain is one modifiable factor in this period. The purpose of this study is to conduct a meta-analysis of AP-induced weight and body mass index (BMI) change in FEP. Methods-A comprehensive literature search identified 28 articles that reported data on APspecific weight or BMI change in FEP. We conducted a meta-analysis of short-and long-term mean weight and BMI differences between placebo and AP medications. We also performed subgroup and meta-regression analysis to examine weight, BMI outcomes and their relationship with location (Asian vs. Western), sponsorship and baseline weight and BMIs. Results-Compared to placebo, AP-caused mean weight gain was 3.22 kg and 1.4 points BMI in the short-term, and 5.30 kg and 1.86 points BMI in the long term. Clinically significant weight gain risk increased about twofold with AP use. Weight gain was associated with duration of AP use. AP medications were associated with more weight gain in Western samples as opposed to Asian samples. Most AP medications were associated with significant body weight gain and BMI increase in FEP patients, except for ziprasidone. Olanzapine and clozapine caused the highest weight gain compared to placebo. Conclusion-Except for ziprasidone, most AP medications were associated with body weight gain and BMI increase in FEP patients. Early and continuing effects of various AP medications on weight gain and BMI increase should be taken into consideration by clinicians.

A typical Antipsychotic Induced Weight Gain: Pathophysiology and Management

Annals of Clinical Psychiatry, 2004

There is compelling evidence that patients with schizophrenia are prone to gain weight. In addition, atypical antipsychotic (AAP) drugs also induce weight gain. All antipsychotic drugs produce weight gain but the potential varies. Many studies overwhelmingly confirm that AAP drugs produce substantially more weight gain in comparison to conventional antipsychotic drugs. Clozapine and olanzapine have the most weight inducing potential. Even ziprasidone, which is considered to be weight neutral, and aripiprazole a dopamine modulator produce weight gain in some. The pathophysiology of weight gain is complicated. Many neurohormones, neuropeptides, gut hormones, as well as adipose tissue and hair root derived hormones interact with environmental factors to produce weight gain. Management of weight gain is a difficult problem. Basic to treatment is an understanding of the etiology. Drug induced obesity provides a unique opportunity to psychiatrists to understand this clinically important problem. In the absence of this knowledge, prevention is the best hope. Education, diet control and simple behavioral measures may prevent excessive weight gain. In those with weight gain, treatment can be attempted with pharmacotherapy with careful monitoring of the side effects. Keywords Atypical antipsychotic induced weight gain; Weight gain and drugs; Management of drug-induced weight gain; Pathophysiology of weight gain; Schizophrenia and weight gain.

Atypical Antipsychotic Induced Weight Gain in Schizophrenic Patients

Indonesian Journal of Clinical Pharmacy, 2021

Atypical antipsychotics are widely prescribed and have the potential to cause weight gain, which may result in the development of metabolic syndrome. Also, it is important to monitor the use of atypical antipsychotic for metabolic disturbance. The purpose of this study is to determine the side effects of atypical antipsychotics in increasing body weight in schizophrenia patients after 4 weeks of use. Furthermore, a retrospective design was conducted and data were collected based on consecutive sampling in 80 adult psychiatric inpatients (20 women and 60 men) with initial diagnoses of schizophrenia and with the same daily nutrition. The patients were hospitalized from January to March 2019, within the term (over 4 weeks) of initiation atypical antipsychotic. The patient body weight was collected before and 4 weeks after the treatment of atypical antipsychotic. The results showed that patients (20 women and 60 men) receiving atypical antipsychotic had a mean age of 35.6 years and a pe...

Weight gain from novel antipsychotic drugs: need for action

General Hospital Psychiatry, 2000

Obesity is common in schizophrenia, and people with schizophrenia appear to be at increased risk for certain obesity-related conditions, such as type 2 diabetes and cardiovascular disease. Antipsychotic drugs, used chronically to control symptoms of schizophrenia, are associated with oftensubstantial weight gain, a side effect that is a special concern with the latest generation of highly effective "novel" agents. That the most effective (e.g., novel) antipsychotic medications lead to substantial weight gain presents the field with a critical public health problem. Although preliminary data have been reported regarding the beneficial use of behavior therapy programs for short-term weight control in patients with schizophrenia, the available data are quite limited, and there are no data regarding the long-term beneficial effects of these programs in this population. The obesity field recently has developed programs emphasizing "lifestyle changes" (e.g., diet, exercise, and problem-solving skills) to successfully manage weight in patients without schizophrenia. Such programs can be adapted for patients with schizophrenia through the use of highly structured and operationalized modules emphasizing medication compliance, social skills development, and participation in outpatient programs. Moreover, these programs can potentially be combined with the use of adjunctive pharmacotherapy to maximize and maintain weight loss. The field must solve the paradox that some of our most effective medications for schizophrenia produce substantial weight gain and its associated troubling health risks.

Weight gain and antipsychotics. Data from EUFEST study

Context. Schizophrenia is a chronic disease most frequently necessitating lifelong antipsychotic treatment. Selecting which antipsychotic is to be prescribed in an individual schizophrenia patient represents an important clinical decision that need to take into account efficacy and side effects. Objective. Evaluating weight gain related with one year antipsychotic treatment in antipsychotic naive firstepisode schizophrenia patients. Design. This study is an analysis of weight gain associated with typical or atypical antipsychotics used in European First Episode Schizophrenia Trial (EUFEST) study. Subjects and Methods. 113 first episode naïve antipsychotic schizophrenia patients included in EUFEST - Romanian cohort, who were randomized to one of the 5 treatment arms. Weight was obtained at baseline, 3, 6, 9 and 12 months for the 5 antipsychotics (typical-Haloperidol; atypical-Olanzapine, Amisulpride, Ziprasidone, Quetiapine). Results. There are no statistically significant differences between groups treated with typical or atypical antipsychotics or between any individual antipsychotics concerning weight gain during the study. Weight gain was the highest in the first 3 months (57.49%) for all the studied neuroleptics. At the end of the study, the less increase was observed with ziprasidone (3.87 kg) and the highest with olanzapine (9.83 kg). Conclusion. Increase in weight has taken place for each individual neuroleptic, but also as a group (all neuroleptics) in the first three months (57.49%). Therefore, we should address the issue of weight gain with great care, especially in first period of antipsychotic administration, in order to fast deploy intervention tailored to maintain pretreatment weight.

Effectiveness of medications used to attenuate antipsychotic-related weight gain and metabolic abnormalities: a systematic review and meta-analysis

Neuropsychopharmacology, 2010

Antipsychotic-related weight gain and metabolic effects are a critical outcome for patients requiring these medications. A literature search using MEDLINE, Web of Science, PsycNET, and EMBASE for randomized, open and double-blind, placebo-controlled trials of medications targeting antipsychotic-induced weight gain was performed. Primary outcome measures were change and endpoint values in body weight and body mass index (BMI). Secondary outcomes included X7% weight gain, all-cause discontinuation, change in waist circumference, glucose and lipid metabolism parameters, and psychiatric symptoms. Sensitivity analyses were conducted to explain heterogeneity of the results. Across 32 studies including 1482 subjects, 15 different medications were tested: amantadine, dextroamphetamine, d-fenfluramine, famotidine, fluoxetine, fluvoxamine, metformin, nizatidine, orlistat, phenylpropanolamine, reboxetine, rosiglitazone, sibutramine, topiramate, and metformin + sibutramine. Compared with placebo, metformin had the greatest weight loss (N ¼ 7, n ¼ 334, À2.94 kg (confidence interval (CI:À4.89,À0.99)), followed by d-fenfluramine (N ¼ 1, n ¼ 16, À2.60 kg (CI:À5.14,À0.06)), sibutramine (N ¼ 2, n ¼ 55, À2.56 kg (CI:À3.91,À1.22)), topiramate (N ¼ 2, n ¼ 133, À2.52 kg (CI:À4.87,À0.16)), and reboxetine (N ¼ 2, n ¼ 79, À1.90 kg (CI:À3.07,À0.72)). Weight loss remained significant with metformin initiation after weight gain had occurred, but not when started concomitantly with antipsychotics. Nausea rates were not higher with any treatment compared with placebo. In all, 5 of 15 psychopharmacologic interventions aimed at ameliorating antipsychotic-induced weight gain outperformed placebo. Results were most robust for metformin, although these were modest and heterogeneous. Only one (negative) combination treatment study was available and head-to-head studies are absent. None of the agents were able to entirely reverse weight gain because of antipsychotics. At present, no treatment has sufficient evidence to recommend broad clinical usage. Antipsychotics with no or minimal cardiometabolic liability, as well as interventions that prevent or normalize adverse antipsychotic cardiometabolic effects are needed.

Almost All Antipsychotics Result in Weight Gain: A Meta-Analysis

PLoS ONE, 2014

Introduction: Antipsychotics (AP) induce weight gain. However, reviews and meta-analyses generally are restricted to second generation antipsychotics (SGA) and do not stratify for duration of AP use. It is hypothesised that patients gain more weight if duration of AP use is longer.
