Impact of glucagon-like peptide receptor agonists on endoscopy and its preoperative management: Guidelines, challenges, and future directions

Glucagon-like peptide receptor agonists(GLP-1RA)are used to treat type 2 diabetes mellitus and,more recently,have garnered attention for their effect-iveness in promoting weight loss.They have been associated with several gastrointestinal adverse effects,including nausea and vomiting.These side effects are presumed to be due to increased residual gastric contents.Given the potential risk of aspiration and based on limited data,the American Society of Anesthesi-ologists updated the guidelines concerning the preoperative management of patients on GLP-1RA in 2023.They included the duration of mandated cessation of GLP-1RA before sedation and usage of“full stomach”precautions if these medications were not appropriately held before the procedure.This has led to additional challenges,such as extended waiting time,higher costs,and increased risk for patients.In this editorial,we review the current societal guidelines,clinical practice,and future directions regarding the usage of GLP-1RA in patients undergoing an endoscopic procedure.

Interplay of gut microbiota,glucagon-like peptide receptor agonists,and nutrition:New frontiers in metabolic dysfunction-associated steatotic liver disease therapy

The gut-liver axis plays a crucial role in the development and progression of metabolic dysfunction-associated steatotic liver disease(MASLD).Key metabolites,including lipopolysaccharides,short-chain fatty acids(SCFAs),bile acids,and beneficial gut bacteria such as Bifidobacterium and Lactobacillus,are pivotal in this process.Glucagon-like peptide-1 receptor agonists(GLP-1 RAs)show promise in managing MASLD by promoting weight loss,enhancing insulin secretion,and improving liver health.They restore gut-liver axis functionality,and their effects are amplified through dietary modifications and gut microbiometargeted therapies.Emerging research highlights the interplay between GLP-1 RAs and gut microbiota,indicating that the gut microbiome significantly influences therapeutic outcomes.Metabolites produced by gut bacteria,can stimulate glucagon-like peptide-1(GLP-1)secretion,further improving metabolic health.Integrating dietary interventions with GLP-1 RA treatment may enhance liver health by modulating the gut microbiota-SCFAs-GLP-1 pathway.Future research is needed to understand personalized effects,with prebiotics and probiotics offering treatment avenues for MASLD.

Glucagon-like peptide-1 receptor agonists as a possible intervention to delay the onset of type 1 diabetes:A new horizon

Type 1 diabetes(T1D)is a chronic autoimmune condition that destroys insulinproducing beta cells in the pancreas,leading to insulin deficiency and hyperglycemia.The management of T1D primarily focuses on exogenous insulin replacement to control blood glucose levels.However,this approach does not address the underlying autoimmune process or prevent the progressive loss of beta cells.Recent research has explored the potential of glucagon-like peptide-1 receptor agonists(GLP-1RAs)as a novel intervention to modify the disease course and delay the onset of T1D.GLP-1RAs are medications initially developed for treating type 2 diabetes.They exert their effects by enhancing glucose-dependent insulin secretion,suppressing glucagon secretion,and slowing gastric emptying.Emerging evidence suggests that GLP-1RAs may also benefit the treatment of newly diagnosed patients with T1D.This article aims to highlight the potential of GLP-1RAs as an intervention to delay the onset of T1D,possibly through their potential immunomodulatory and anti-inflammatory effects and preservation of beta-cells.This article aims to explore the potential of shifting the paradigm of T1D management from reactive insulin replacement to proactive disease modification,which should open new avenues for preventing and treating T1D,improving the quality of life and long-term outcomes for individuals at risk of T1D.

Glucagon-like peptide 1 receptor agonist:A potential game changer for cholangiocarcinoma

Glucagon-like peptide-1 receptor(GLP-1R)agonist,a subgroup of incretin-based anti-diabetic therapies,is an emerging medication with benefits in reducing blood glucose and weight and increasing cardiovascular protection.Contrarily,concerns have been raised about GLP-1R agonists increasing the risk of particular cancers.Recently,several epidemiological studies reported contradictory findings of incretin-based therapy on the risk modification for cholangiocarcinoma(CCA).The first cohort study demonstrated that incretin-based therapy was associated with an increased risk of CCA.Later studies,however,showed a null effect of incretinbased therapy on CCA risk for dipeptidyl peptidase-4 inhibitor nor GLP-1R agonist.Mechanistically,glucagon-like peptide 1 receptor is multifunctional,including promoting cell growth.High GLP-1R expressions were associated with progressive phenotypes of CCA cells in vitro.Unexpectedly,the GLP-1R agonist showed anti-tumor effects on CCA cells in vitro and in vivo with unclear mechanisms.Our recent report also showed that GLP-1R agonists suppressed the expression of GLP-1R in CCA cells in vitro and in vivo,leading to the inhibition of CCA tumor growth.This editorial reviews recent evidence,discusses the potential effects of GLP-1R agonists in CCA patients,and proposes underlying mechanisms that would benefit from further basic and clinical investigation.

Glucagon-like peptide-1 receptor agonists:Exploring the mechanisms from glycemic control to treatment of multisystemic diseases

This editorial takes a deeper look at the insights provided by Soresi and Giannitrapani,which examined the therapeutic potential of glucagon-like peptide-1 receptor agonists(GLP-1RAs)for metabolic dysfunction-associated fatty liver disease.We provide supplementary insights to their research,highlighting the broader systemic implications of GLP-1RAs,synthesizing the current understanding of their mechanisms and the trajectory of research in this field.GLP-1RAs are revolutionizing the treatment of type 2 diabetes mellitus and beyond.Beyond glycemic control,GLP-1RAs demonstrate cardiovascular and renal protective effects,offering potential in managing diabetic kidney disease alongside renin–angiotensin–aldosterone system inhibitors.Their role in bone metabolism hints at benefits for diabetic osteoporosis,while the neuroprotective properties of GLP-1RAs show promise in Alzheimer's disease treatment by modulating neuronal insulin signaling.Additionally,they improve hormonal and metabolic profiles in polycystic ovary syndrome.This editorial highlights the multifaceted mechanisms of GLP-1RAs,emphasizing the need for ongoing research to fully realize their therapeutic potential across a range of multisystemic diseases.

A Retrospective Analysis of Glucagon-Like Peptide 1 Receptor Agonists in Treating Type 2 Diabetes Mellitus Complicated by Nonalcoholic Fatty Liver Disease

Background: The objective of this study was to compare and analyze the variations in clinical indices before and after treatment of type 2 mellitus (T2DM) combined with nonalcoholic fatty liver disease (NAFLD) that were treated with glucagon-like peptide 1 receptor agonists (GLP-1RAs). Methods: The electronic medical record system was utilized to search for a total of 16 patients with type 2 diabetes complicated by NAFLD who were hospitalized at the First Affiliated Hospital of Yangtze University from October 2022 to April 2023 and treated with GLP-1RA for the first time. The clinical indices were compared before and after 12 weeks of treatment with GLP-1RA. Results: The liver-spleen CT ratio (L/S), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) in all patients treated with GLP-1RA after 12 weeks were significantly different (P 0.05). The patients were categorized into two groups based on the types of GLP-1RAs. The changes in L/S, TC, TG, and LDL-C in the long-acting group after treatment were statistically significant (P Conclusions: GLP-1RAs can improve liver function, regulate lipid metabolism, and reduce the severity of fatty liver in patients with T2DM complicated by NAFLD, which demonstrates the importance of clinical applications.

Glucagon-like peptide 1 receptor activation:anti-inflammatory effects in the brain

The glucagon-like peptide 1 is a pleiotropic hormone that has potent insulinotropic effects and is key in treating metabolic diseases such as diabetes and obesity.Glucagon-like peptide 1 exerts its effects by activating a membrane receptor identified in many tissues,including diffe rent brain regions.Glucagon-like peptide 1 activates several signaling pathways related to neuroprotection,like the support of cell growth/survival,enhancement promotion of synapse formation,autophagy,and inhibition of the secretion of proinflammatory cytokines,microglial activation,and apoptosis during neural morphogenesis.The glial cells,including astrocytes and microglia,maintain metabolic homeostasis and defe nse against pathogens in the central nervous system.After brain insult,microglia are the first cells to respond,followed by reactive astrocytosis.These activated cells produce proinflammato ry mediators like cytokines or chemokines to react to the insult.Furthermore,under these circumstances,mic roglia can become chro nically inflammatory by losing their homeostatic molecular signature and,consequently,their functions during many diseases.Several processes promote the development of neurological disorders and influence their pathological evolution:like the formation of protein aggregates,the accumulation of abnormally modified cellular constituents,the formation and release by injured neurons or synapses of molecules that can dampen neural function,and,of critical impo rtance,the dysregulation of inflammato ry control mechanisms.The glucagonlike peptide 1 receptor agonist emerges as a critical tool in treating brain-related inflammatory pathologies,restoring brain cell homeostasis under inflammatory conditions,modulating mic roglia activity,and decreasing the inflammato ry response.This review summarizes recent advances linked to the anti-inflammato ry prope rties of glucagon-like peptide 1 receptor activation in the brain related to multiple sclerosis,Alzheimer’s disease,Parkinson’s disease,vascular dementia,or chronic migraine.

Glucagon-like peptide-1 agonists:Role of the gut in hypoglycemia unawareness,and the rationale in type 1 diabetes

Type 1 diabetes is increasing and the majority of patients have poor glycemic control.Although advanced technology and nanoparticle use have greatly enhanced insulin delivery and glucose monitoring,weight gain and hypoglycemia remain major challenges and a constant source of concern for patients with type 1 diabetes.Type 1 diabetes shares some pathophysiology with type 2 diabetes,and an overlap has been reported.The above observation created great interest in glucagon-like peptide-1 receptor agonists(GLP-1)as adjuvants for type 1 diabetes.Previous trials confirmed the positive influence of GLP-1 agonists onβcell function.However,hypoglycemia unawareness and dysregulated glucagon response have been previously reported in patients with recurrent hypoglycemia using GLP-1 agonists.Jin et al found that the source of glucagon dysregulation due to GLP-1 agonists resides in the gut.Plausible explanations could be gut nervous system dysregulation or gut microbiota disruption.This review evaluates the potential of GLP-1 agonists in managing type 1 diabetes,particularly focusing on their impact on glycemic control,weight management,and glucagon dysregulation.We provide a broader insight into the problem of type 1 diabetes mellitus management in the light of recent findings and provide future research directions.

Effects of glucagon-like peptide-1 receptor agonists on glucose excursion and inflammation in overweight or obese type 2 diabetic patients

BACKGROUND Currently,the lack of comparative studies between weekly and daily formulations of glucagon-like peptide-1 receptor agonists(GLP-1RAs)for glucose excursion is worth investigation.AIM To investigate the effects of weekly and daily formulations of GLP-1RA on glucose excursion and inflammation in overweight and obese patients with type 2 diabetes.METHODS Seventy patients with type 2 diabetes mellitus who were treated at our hospital between January 2019 and January 2022 were enrolled in this retrospective analysis.All patients were treated with metformin.We evaluated changes in blood glucose levels and a series of important indicators in patients before and after treatment with either a weekly or daily preparation of GLP-1RA(group A;n=33 and group B;n=37).RESULTS The degree of decrease in the levels of fasting blood glucose,mean blood glucose,mean amplitude of glycemic excursions,total cholesterol,triglycerides,tumor necrosis factor-α,interleukin-6,and high-sensitivity C-reactive protein after treatment in group A was higher than that in group B(P<0.05),whereas the 2-h postprandial blood glucose levels decreased more so in group B than in group A(P<0.001).However,there were no statistically significant differences in the levels of glycated hemoglobin,standard deviation of blood glucose,coefficient of variation,absolute mean of daily differences,percentage of time with 3.9 mmol/L<glucose<10 mmol/L,and high-and low-density lipoproteins between the two groups(P>0.05).The incidence of adverse reactions was significantly lower in group A than in group B(P<0.05).CONCLUSION The effect of the weekly preparation of GLP-1RA in controlling blood glucose levels in the patients,suppressing inflammation,and reducing adverse reactions was significantly higher than that of the daily preparations,which is worthy of clinical promotion.

Effects of glucagon-like peptide-1 receptor agonists on non-alcoholic fatty liver disease and inflammation

Glucagon-like peptide1 (GLP-1) is secreted from Langerhans cells in response to oral nutrient intake. Glucagon- like peptide-1 receptor agonists (GLP-1RAs) are a new class of incretin-based anti-diabetic drugs. They function to stimulate insulin secretion while suppressing glucagon secretion. GLP-1-based therapies are now well established in the management of type 2 diabetes mellitus (T2DM), and recent literature has suggested potential applications of these drugs in the treatment of obesity and for protection against cardiovascular and neurological diseases. As we know, along with change in lifestyles, the prevalence of non-alcoholic fatty liver disease (NAFLD) in China is rising more than that of viral hepatitis and alcoholic fatty liver disease, and NAFLD has become the most common chronic liver disease in recent years. Recent studies further suggest that GLP-1RAs can reduce transaminase levels to improve NAFLD by improving blood lipid levels, cutting down the fat content to promote fat redistribution, directly decreasing fatty degeneration of the liver, reducing the degree of liver fibrosis and improving inflammation. This review shows the NAFLD-associated effects of GLP-1RAs in animal models and in patients with T2DM or obesity who are participants in clinical trials. (C) 2014 Baishideng Publishing Group Inc.

Effects of glucagon-like peptide-1 receptor agonists on renal function

Glucagon-like peptide-1(GLP-1)receptor agonists result in greater improvements in glycemic control than placebo and promote weight loss with minimal hypoglycemia in patients with type 2 diabetes mellitus.A number of case reports show an association of GLP-1receptor agonists,mainly exenatide,with the development of acute kidney injury.The present review aims to present the available data regarding the effects of GLP-1 receptor agonists on renal function,their use in subjects with chronic renal failure and their possible association with acute kidney injury.Based on the current evidence,exenatide is eliminated by renal mechanisms and should not be given in patients with severe renal impairment or end stage renal disease.Liraglutide is not eliminated by renal or hepatic mechanisms,but it should be used with caution since there are only limited data in patients with renal or hepatic impairment.There is evidence from animal studies that GLP-1 receptor agonists exert protective role in diabetic nephropathy with mechanisms that seem to be independent of their glucose-lowering effect.Additionally,there is evidence that GLP-1 receptor agonists influence water and electrolyte balance.These effects may represent new ways to improve or even prevent diabetic nephropathy.

Review on the Effect of Glucagon-Like Peptide-1 Receptor Agonists and Dipeptidyl Peptidase-4 Inhibitors for the Treatment of Non-Alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease（NAFLD） is a common liver disease and it represents the hepatic manifestation of metabolic syndrome, which includes type 2 diabetes mellitus（T2DM）, dyslipidemia, central obesity and hypertension. Glucagon-like peptide-1（GLP-1） analogues and dipeptidyl peptidase-4（DPP-4） inhibitors were widely used to treat T2 DM. These agents improve glycemic control, promote weight loss and improve lipid metabolism. Recent studies have demonstrated that the GLP-1 receptor（GLP-1R） is present and functional in human and rat hepatocytes. In this review, we present data from animal researches and human clinical studies that showed GLP-1 analogues and DPP-4 inhibitors can decrease hepatic triglyceride（TG） content and improve hepatic steatosis, although some effects could be a result of improvements in metabolic parameters. Multiple hepatocyte signal transduction pathways and m RNA from key enzymes in fatty acid metabolism appear to be activated by GLP-1 and its analogues. Thus, the data support the need for more rigorous prospective clinical trials to further investigate the potential of incretin therapies to treat patients with NAFLD.

Is there a role for glucagon-like peptide-1 receptor agonists in the management of diabetic nephropathy?

Chronic kidney disease constitutes a major microvascular complication of diabetes mellitus.Accumulating data suggest that glucagon-like peptide-1 receptor agonists(GLP-1 RAs)might have a role in the management of diabetic kidney disease(DKD).GLP-1 RAs appear to reduce the incidence of persistent macro-albuminuria in patients with type 2 diabetes mellitus.This beneficial effect appears to be mediated not only by the glucose-lowering action of these agents but also on their blood pressure lowering,anti-inflammatory and antioxidant effects.On the other hand,GLP-1 RAs do not appear to affect the rate of decline of glomerular filtration rate.However,this might be due to the relatively short duration of the trials that evaluated their effects on DKD.Moreover,these trials were not designed nor powered to assess renal outcomes.Given than macrolbuminuria is a strong risk factor for the progression of DKD,it might be expected that GLP-1 RAs will prevent the deterioration in renal function in the long term.Nevertheless,this remains to be shown in appropriately designed randomized controlled trials in patients with DKD.

Glucagon-like peptide-1 receptor agonists in non-alcoholic fatty liver disease: An update

Non-alcoholic fatty liver disease(NAFLD)is the predominant cause of chronic liver disease worldwide.NAFLD progresses in some cases to non-alcoholic steatohepatitis(NASH),which is characterized,in addition to liver fat deposition,by hepatocyte ballooning,inflammation and liver fibrosis,and in some cases may lead to hepatocellular carcinoma.NAFLD prevalence increases along with the rising incidence of type 2 diabetes mellitus(T2DM).Currently,lifestyle interventions and weight loss are used as the major therapeutic strategy in the vast majority of patients with NAFLD.Glucagon-like peptide-1 receptor agonists(GLP-1RAs)are used in the management of T2DM and do not have major side effects like hypoglycemia.In patients with NAFLD,the GLP-1 receptor production is down-regulated.Recently,several animal and human studies have emphasized the role of GLP-1RAs in ameliorating liver fat accumulation,alleviating the inflammatory environment and preventing NAFLD progression to NASH.In this review,we summarize the updated literature data on the beneficial effects of GLP-1RAs in NAFLD/NASH.Finally,as GLP-1RAs seem to be an attractive therapeutic option for T2DM patients with concomitant NAFLD,we discuss whether GLP-1RAs should represent the first line pharmacotherapy for these patients.

Development of therapeutic options on type 2 diabetes in years:Glucagon-like peptide-1 receptor agonist’s role intreatment; from the past to future

Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia.Type 2 diabetes (T2DM) accounting for 90% of cases globally.The worldwide prevalence of DM is rising dramatically over the last decades,from 30 million cases in 1985 to 382 million cases in 2013.It’s estimated that 451 million people had diabetes in 2017.As the pathophysiology was understood over the years,treatment options for diabetes increased.Incretin-based therapy is one of them.Glucagon-like peptide-1 receptor agonist (GLP-1 RA) not only significantly lower glucose level with minimal risk of hypoglycemia but also,they have an important advantage in themanagement of cardiovascular risk and obesity.Thus,we will review here GLP-1 RAsrole in the treatment of diabetes.

Glucagon-like peptide-1 receptor agonists favorably address all components of metabolic syndrome

Cardiovascular death is the leading cause of mortality for patients with type 2 diabetes mellitus. The etiologyof cardiovascular disease in diabetes may be divided into hyperglycemia per se and factors operating through components of metabolic syndrome(Met S). Hyperglycemia causes direct injury to vascular endothelium and possibly on cardiac myocytes. Met S is a cluster of risk factors like obesity, hyperglycemia, hypertension and dyslipidemia. The incidence of this syndrome is rising globally. Glucagon-like peptide-1 receptor agonists(GLP-1RA) are a group of drugs, which address all components of this syndrome favorably. Experimental evidence suggests that they have favorable actions on myocardium as well. Several compounds belonging to GLP-1RA class are in market now and a large number awaiting their entry. Although, originally this class of drugs emerged as a treatment for type 2 diabetes mellitus, more recent data generated revealed beneficial effects on multiple metabolic parameters. We have studied literature published between 2000 and 2016 to look into effects of GLP-1RA on components of Met S. Results from recently concluded clinical trials suggest that some of the molecules in this class may have favorable effects on cardiovascular outcome.

Analysis of long noncoding RNA-associated competing endogenous RNA network in glucagon-like peptide-1 receptor agonist-mediated protection inβcells

BACKGROUND Long noncoding RNAs(lncRNAs)and mRNAs are widely involved in various physiological and pathological processes.The use of glucagon-like peptide-1 receptor agonists(GLP-1RAs)is a novel therapeutic strategy that could promote insulin secretion and decrease the rate ofβ-cell apoptosis in type 2 diabetes mellitus(T2DM)patients.However,the specific lncRNAs and mRNAs and their functions in these processes have not been fully identified and elucidated.AIM To identify the lncRNAs and mRNAs that are involved in the protective effect of GLP-1RA inβcells,and their roles.METHODS Rat gene microarray was used to screen differentially expressed(DE)lncRNAs and mRNAs inβcells treated with geniposide,a GLP-1RA.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses were performed to assess the underlying functions of DE mRNAs.Hub mRNAs were filtered using the STRING database and the Cytoscape plugin,CytoHubba.In order to reveal the regulatory relationship between lncRNAs and hub mRNAs,their co-expression network was constructed based on the Pearson coefficient of DE lncRNAs and mRNAs,and competing endogenous RNA(ceRNA)mechanism was explored through miRanda and TargetScan databases.RESULTS We identified 308 DE lncRNAs and 128 DE mRNAs with a fold change filter of≥1.5 and P value<0.05.GO and KEGG pathway enrichment analyses indicated that the most enriched terms were G-protein coupled receptor signaling pathway,inflammatory response,calcium signaling pathway,positive regulation of cell proliferation,and ERK1 and ERK2 cascade.Pomc,Htr2a,and Agtr1a were screened as hub mRNAs using the STRING database and the Cytoscape plugin,CytoHubba.This result was further verified using SwissTargetPrediction tool.Through the co-expression network and competing endogenous(ceRNA)mechanism,we identified seven lncRNAs(NONRATT027738,NONRATT027888,NONRATT030038,etc.)co-expressed with the three hub mRNAs(Pomc,Htr2a,and Agtr1a)based on the Pearson coefficient of the expression levels.These lncRNAs regulated hub mRNA functions by competing with six miRNAs(rno-miR-5132-3p,rno-miR-344g,rno-miR-3075,etc.)via the ceRNA mechanism.Further analysis indicated that lncRNA NONRATT027738 interacts with all the three hub mRNAs,suggesting that it is at a core position within the ceRNA network.CONCLUSION We have identified key lncRNAs and mRNAs,and highlighted here how they interact through the ceRNA mechanism to mediate the protective effect of GLP-1RA inβcells.

Glucagon-like peptide 1 receptor governs Wnt signaling to promote bone formation

Our previous investigation found that exendin-4 （Ex-4） , a peptide analogue of glucagon-like peptide 1 （GLP-1） , induced bone formation probably by osteoblast activation. Nevertheless, previous investigations did not observe any expression of GLP-1 receptors in osteoblasts, indicating that the direct cell target of GLP-1 and its ana- logues might not be osteoblasts but some other types of cells yet to be identified. To elucidate the underlying mecha- nisms, we performed further investigation in the present study and found that GLP-1 receptor was only identified in bone marrow mesenchymal stem cells （BMSCs）. Furthermore, activation of GLP-1 receptor by Ex-4 promoted the differentiation of B MSCs into osteoblast, which was associated with activation of PKA, nuclear translocation of [5- catenin, activation of PI3K/AKT and inhibition of GSK3β. Ex-4 also inhibited the adipocyte differentiation of BM- SCs, as evidenced by inhibition of PPARγ, lipoprotein lipase expression and lipid production. Blockade of GLP-1 receptor, PKA, PI3K or Wnt pathway, or respective knock-down of GLP-1 receptor and β-catenin in BMSCs inhib- ited the Ex-4 mediated effects. The results indicated that the GLP-1 receptor mediated osteoblastic differentiation and bone formation through stimulation of PKA/β-catenin signaling and inhibition of PKA/PI3IC/AKT/GSK3β？ signaling pathway in BMSCs. The findings reveal a new role of GLP-1 receptor for regulating osteoblastic differentia- tion of B MSCs and may provide a molecular basis for novel anabolic therapeutics against osteoporosis.

Antihypertensive Effect of Sodium-Glucose Cotransporter 2 Inhibitors and Glucagon-like Peptide 1 Receptor Agonists

An increasing body of evidence shows that new antidiabetic drugs—particularly sodium-glucose cotransporter 2(SGLT2)inhibitors and glucagon-like peptide 1(GLP-1)receptor agonists—have a beneficial effect on cardiovascular outcome.The majority of these studies have been performed in patients with heart failure and the results have shown first positive effect on blood pressure(BP)reduction.These effects are more pronounced with SGLT2 inhibitors than with GLP-1 receptor agonists.However,the reasons and mechanisms of action inducing BP reduction are still not sufficiently clear.Proposed mechanisms of SGLT2 inhibitors involve the natriuretic effect,modification of the renin-angiotensin-aldosterone system,and/or the reduction in the sympathetic nervous system.GLP-1 receptor agonists have several mechanisms that are related to glycemic,weight,and BP control.Current data show that SGLT2 inhibitors have a stronger antihypertensive effect than GLP-1 receptor agonists,which is mainly related to their renal effect.Briefly,SGLT2 inhibitors increase the response to diuretics and decrease the meal-related antinatriuretic pressure by lowering post-prandial hyperglycemia and hyperinsulinemia and prevent proximal sodium reabsorption.SGLT2 inhibitors can be used as second-line therapy in patients with diabetes mellitus or heart disease and concomitant hypertension.This article aims to summarize current knowledge regarding the antihypertensive effect of SGLT2 inhibitors and GLP-1 receptor agonists.
