NALTREXONE OBESITY

OBJECTIVE: Little is known about the effect of a multi-drug weight loss strategy in obesity treatment, particularly combining bupropion/naltrexone and glucagon-like peptide 1 (GLP-1) analogue. The purpose of this study was to evaluate if there are any additive effects of prescribing bupropion/naltrexone on top of GLP-1 analogue as weight loss therapy. METHODS: This was a retrospective cohort study of adult patients with a body mass index (BMI) ≥ 30 kg/m2 prescribed GLP-1 analogue therapy at an obesity specialist clinic in Vancouver, Canada...

Medications for obesity have been studied in various populations over the past three decades. We aimed to quantify the baseline demographic characteristics of BMI, sex, age, and race in randomised clinical trials (RCTs) across three decades to establish whether the population studied is representative of the global population affected by the disease. Clinical trials of 12 medications for obesity (ie, orlistat, naltrexone-bupropion, topiramate-phentermine, liraglutide, semaglutide, lorcaserin, sibutramine, rimonabant, taranabant, tirzepatide, retatrutide, and orforglipron) published from Jan 20, 1999, to Nov 12, 2023, were assessed through a systematic review for methodological quality and baseline demographic characteristics...

INTRODUCTION: Obesity is the modern world's current epidemic, with substantial health and economic impact. This study aimed to provide a narrative overview of the past, currently available, and future treatment options that offer therapeutic and preventive advantages for obesity management. AREAS COVERED: Historically, rimonabant, and lorcaserin, were approved and used for managing non-syndromic obesity. Currently, orlistat, naltrexone/bupropion, glucagon-like peptide-1 receptor agonist (GLP-1 RA), and a few promising therapeutic agents are under investigation, including retatrutide, cagrilintide and orforglipron, which show promising weight reduction effects...

BACKGROUND: The global prevalence of obesity and overweight is a significant concern in the field of public health. However, addressing and combating these conditions pose considerable challenges. Numerous interventional studies have been conducted to assess the possible impact of bupropion on weight reduction. The primary objective of this study was to conduct a comprehensive investigation into the effects of bupropiona alone and in combination with naltrexone on weight, body mass index (BMI), and waist circumferences (WC)...

AIM: This guideline (GL) is aimed at providing a clinical practice reference for the management of adult patients with overweight or obesity associated with metabolic complications who are resistant to lifestyle modification. METHODS: Surgeons, endocrinologists, gastroenterologists, psychologists, pharmacologists, a general practitioner, a nutritionist, a nurse and a patients' representative acted as multi-disciplinary panel. This GL has been developed following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach...

Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, constitutes a metabolic disorder frequently associated with obesity and insulin resistance (IR). Furthermore, women with PCOS often suffer from excessive anxiety and depression, elicited by low self-esteem due to obesity, acne, and hirsutism. These mood disorders are commonly associated with food cravings and binge eating. Hypothalamic signaling regulates appetite and satiety, deteriorating excessive food consumption...

BACKGROUND: Pharmacotherapy provides an option for adults with overweight and obesity to reduce their bodyweight if lifestyle modifications fail. We summarised the latest evidence for the benefits and harms of weight-lowering drugs. METHODS: This systematic review and network meta-analysis included searches of PubMed, Embase, and Cochrane Library (CENTRAL) from inception to March 23, 2021, for randomised controlled trials of weight-lowering drugs in adults with overweight and obesity...

BACKGROUND: Several studies have demonstrated that early childhood and adolescent obesity are risk factors for multiple sclerosis (MS) susceptibility. Obesity is thought to share inflammatory components with MS through overproduction of pro-inflammatory adipokines (e.g., leptin) and reduction of anti-inflammatory adipokines (e.g, adiponectin). Recently, drug repurposing (i.e. identifying new indications for existing drugs) has garnered significant attention. The US Food and Drug Administration Adverse Event Reporting System (FAERS) database serves not only as a resource for mining adverse drug reactions and safety signals but also for identifying inverse associations and potential medication repurposing opportunities...

PURPOSE: Anti-obesity medications (AOMs), along with lifestyle interventions, are effective means of inducing and maintaining weight loss in patients with obesity. Although the efficacy of AOMs has been reported, there have been no direct comparisons of these drugs. Therefore, in the present study, we aimed to compare the efficacy of all the AOMs available in Korea in a real-world setting. PATIENTS AND METHODS: The body weight and composition of 205 adults treated with phentermine, phentermine/topiramate, liraglutide, naltrexone/bupropion, lorcaserin, or orlistat for at least 6 months were analyzed at 2 month intervals...

The prevalence of obesity with various complications is increasing rapidly in Korea. Although lifestyle modification is fundamental in obesity treatment, more effective treatment tools are required. Many advances in obesity treatment have been reported recently, including lifestyle modifications and pharmacological, endoscopic, and surgical treatments. Drugs with proven long-term efficacy and safety are preferred because management for obesity treatment is a long-term process. Currently, four medications are available for long-term use in Korea: Orlistat, Naltrexone/bupuropion NR, Phentermine/topiramate capsule, and Liraglutide...

PURPOSE: A significant proportion of patients experience insufficient weight loss or weight regain after bariatric surgery. There is a paucity of literature describing anti-obesity medication (AOM) use following bariatric surgery. We sought to identify prevalence and trends of AOM use following bariatric surgery. MATERIALS AND METHODS: We utilized the IBM Explorys® database to identify all adults with prior bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy)...

AIMS: To describe trends in the use of anti-obesity drugs in Norway during the period 2004-2022. MATERIALS AND METHODS: We assessed the annual utilization of any available drug indicated for obesity recorded in the nationwide Norwegian Prescribed Drug Register for adults (age 18-79 years) from 1 January 2004 to 31 December 2022. Prevalence was stratified by sex and age group (18-29 years and 10-year age groups thereafter). Additional analyses were performed in individuals initiating treatment with an anti-obesity drug and on the cost of the anti-obesity drugs since 2017...

Background and Objectives : The NUCB2 gene and its polymorphisms were identified as novel players in the regulation of food intake, potentially leading to obesity (OBE) and altered eating behaviors. Naltrexone/bupropion SR (NB) showed good efficacy and tolerability for treating OBE and altered eating behaviors associated with binge eating disorder (BED). This prospective study investigates the influence of NUCB2 gene polymorphism on NB treatment response in OBE and BED. Materials and Methods : Body mass index (BMI), eating (EDE-Q, BES, NEQ, GQ, Y-FAS 2...

BACKGROUND: Utilization patterns of bariatric surgery among older patients with heart failure (HF), and the associations with cardiovascular outcomes, are not well known. METHODS: Medicare beneficiaries with HF and at least class II obesity from 2013 to 2020 were identified with Medicare Provider Analysis and Review 100% inpatient files and Medicare 5% outpatient files. Patients who underwent bariatric surgery were matched to controls in a 1:2 ratio (matched on exact age, sex, race, body mass index, HF encounter year, and HF hospitalization rate pre-surgery/matched period)...

BACKGROUND: Obesity has reached epidemic proportions, with >40% of the US population affected. Although traditionally managed by lifestyle modification, and less frequently by bariatric therapies, there are significant pharmacological advancements. AIMS: To conduct a narrative review of the neurohormonal and physiological understanding of weight gain and obesity, and the development, clinical testing, indications, expected clinical outcomes, and associated risks of current FDA-approved and upcoming anti-obesity medications (AOMs)...

Opioids regulate various physiological and pathophysiological functions, including cell proliferation, immune function, obesity, and neurodegenerative disorders. They have been used for centuries as a treatment for severe pain, binding to opioid receptors a specific G protein-coupled receptor. Common opioids, like β-endorphin, [D-Ala2, N-MePhe4, Gly-ol]-enkephalin (DAMGO), and dynorphins, have analgesic effects. The use of a potent antagonist, like naltrexone hydrochloride, to block the effects of mu Opioid Receptor (μOR) may result in the withdrawal of physiological effects and could potentially impact immune responses in many diseases including respiratory disease...
