Glucagon sglt2

Juan Rosas-Guzmán, Juan Rosas-Saucedo, Alma R J Romero-García
Type 2 Diabetes Mellitus (T2DM) is a chronic illness with high prevalence in Mexico, Latin-America, and the world and is associated to high morbidity, disability, and mortality rate, especially in developing countries. T2DM physiopathology is very complex; insulin resistance in the muscle, liver, and adipose tissue, a reduction in the production of incretins (mainly GLP-1) in the intestine, increased glucagon synthesis, an insufficient response of insulin generation, and increased glucose reabsorption in the kidney lead all together to an hyperglycemic state, which has been closely associated with the development of micro and macrovascular complications...

Cardiovascular (CV) disease is the leading cause of death in patients with type 2 diabetes mellitus (T2DM). Most published trials of glucose-lowering agents have shown no significant CV benefit or increased risk of death or heart failure, with the exception of metformin. Three novel classes of glucose-lowering agents, dipeptidyl peptidase 4 (DPP-4) inhibitors, glucagon-like peptide 1 (GLP-1) receptor agonists, and sodium glucose cotransporter 2 (SGLT2) inhibitors, have been approved by the FDA for the treatment of T2DM in the United States and other parts of the world in the last decade...

BACKGROUND: Glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce glycaemia and weight, and improve cardiovascular risk factors via different mechanisms. We aimed to compare the efficacy and safety of co-initiation of the GLP-1 receptor agonist exenatide and the SGLT2 inhibitor dapagliflozin with exenatide or dapagliflozin alone in patients with type 2 diabetes inadequately controlled by metformin. METHODS: DURATION-8 was a 28 week, multicentre, double-blind, randomised, active-controlled phase 3 trial done at 109 sites in six countries...

For some time, it has been clear that elevated glucose is detrimental to the organism. A plethora of medicines have been introduced to reduce the fasting and postprandial glucose levels (including insulin, glucagon-like peptide receptor 1 [GLP-1] agonists, and sodium-glucose co-transporter 2 [SGLT2] inhibitors, among others). Although these medications are useful to reduce tissue exposure to glucose, no single compound and no combination have been able to totally normalize the blood sugar. Thus, it was astonishing when it was reported that surgery of the gastrointestinal tract could not only reduce obesity but also normalize the blood sugar...

Glucagon is one of the main regulators of blood glucose levels and dysfunctional stimulus secretion coupling in pancreatic A-cells is believed to be an important factor during development of diabetes. However, regulation of glucagon secretion is poorly understood. Recently it has been shown that Na(+)/glucose co-transporter (SGLT) inhibitors used for the treatment of diabetes increase glucagon levels in man. Here, we show experimentally that the SGLT2 inhibitor dapagliflozin increases glucagon secretion at high glucose levels both in human and mouse islets, but has little effect at low glucose concentrations...

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are the most recent addition to the therapeutic options available for the treatment of type 2 diabetes and became available after the introduction of incretin-based therapies, dipeptidyl peptidase 4 inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs). These agents have potential advantages with regard to their weight loss-promoting effect, low risk of hypoglycemia, reduction in blood pressure, and reduction in cardiovascular events in high-risk patients (with empagliflozin)...

AIMS: Diabetes treatments aim at preventing undesirable metabolic effects of hyperglycemia and at preventing/reducing tissue damage, including cardiovascular (CV) events. For approval, novel diabetes drugs undergo early systematic investigation to assess CV safety. This review provides an updated analysis of the results of recent studies examining novel diabetes medications and CV outcomes. DATA SYNTHESIS: The new regulatory guidelines enforce adjudication of all CV events when testing novel diabetes drugs...

Controversy exists regarding the selection of second-line therapy for patients with type 2 diabetes mellitus (T2DM) who are unable to achieve glycemic control with metformin therapy alone. Newer pharmacologic treatments for T2DM include glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter 2 inhibitors. Both the classes of medication are efficacious, exhibit positive effects on weight, and are associated with minimal risk of hypoglycemia. The purpose of this review is to compare the clinical trial and real-world effectiveness data of glucagon-like peptide-1 receptor agonists versus sodium-glucose cotransporter 2 inhibitors related to A1c reduction, weight loss, cost-effectiveness, cardiovascular outcomes, and safety in patients with T2DM...

Type 2 diabetes mellitus (T2DM) is a global epidemic that poses a major challenge to health-care systems. Improving metabolic control to approach normal glycaemia (where practical) greatly benefits long-term prognoses and justifies early, effective, sustained and safety-conscious intervention. Improvements in the understanding of the complex pathogenesis of T2DM have underpinned the development of glucose-lowering therapies with complementary mechanisms of action, which have expanded treatment options and facilitated individualized management strategies...

OBJECTIVES: This study aimed to investigate changes in levels of biomarkers associated with adipocyte function and insulin and glucagon kinetics after a meal tolerance test (MTT) during treatment with dapagliflozin among obese type 2 diabetes mellitus (T2DM) patients. METHODS: T2DM patients with hemoglobin A1c (HbA1c) levels >6.5 % and body mass index (BMI) >25 kg/m(2) were treated with dapagliflozin 5 mg/day for at least 12 weeks. HbA1c, body weight, ketone bodies, adiponectin, plasminogen activator inhibitor-1 (PAI-1), and C-reactive protein (CRP) were measured before and after treatment with dapagliflozin...

Active sodium-glucose transporters play a role to glucose homeostasis and represent novels targets for the management of type 2 diabetes (T2D). Sodium-glucose cotransporter 1 (SGLT1) is essential for intestinal glucose absorption from the lumen into enterocytes, whereas glucose reabsorption by the kidney is mainly mediated by sodium-glucose cotransporter 2 (SGLT2). SGLT2 inhibitors were developed to occlude SGLT2 glucose reabsorption pathway and cause glycosuria, thereby reducing plasma glucose concentrations...

Diabetic ketoacidosis is a serious metabolic condition that may occur in patients with either Type 1 or Type 2 diabetes. The accumulation of ketoacids in the serum is a consequence of insulin deficiency and glucagon excess. Sodium Glucose Transporter 2 (SGLT2) inhibitors are novel therapeutic treatments for improving glucose homeostasis in patients with diabetes. Through reductions in glucose reabsorption by the kidney, they lower serum glucose in patients with Type 2 diabetes and they improve glucose control whether used alone or in combination with other therapies...

Agents introduced into therapy of type 2 diabetes in the last few years are still the subject of numerous clinical and experimental studies. Although many studies have been completed, we still do not know all aspects of these drugs' action, especially the long-term effects of their use. Most questionable is their impact on the processes of cell proliferation, on the cardiovascular and immune systems, on lipids and uric acid metabolism. A summary of the most important observations on the use of three groups of new drugs - analogs of glucagon-like peptide 1 (GLP-1), inhibitors of dipeptidyl peptidase IV (DPPIV) and inhibitors of sodium glucose cotransporters (SGLT1 and SGLT2) - has been made, based on a review of the literature over the past five years (2010-2014)...

Cardiovascular disease is a major threat to people with diabetes. Attempts have long been made to lower cardiovascular risk by means of glucose-lowering treatment. Initially, it seemed that was an option, but subsequent trials could not verify the original observations and there was concern that some glucose-lowering drugs can actually cause cardiovascular harm. This led medical product agencies in the United States and Europe to require major outcomes trials before accepting new glucose-lowering drugs. The least requirement was noninferiority compared with existing treatment modalities...

Glyxambi(®) (empagliflozin/linagliptin) is a fixed-dose, once-daily tablet combining a sodium glucose co-transporter-2 (SGLT2) inhibitor with a dipeptidyl peptidase-4 (DPP-4) inhibitor. Glyxambi(®) is served as an adjuvant to diet and exercise to improve glycemic control in adults with type 2 diabetes when both empagliflozin and linagliptin are appropriate treatments. Glyxambi(®) combines 10mg or 25mg empagliflozin with 5mg linagliptin, with different, complementary mechanisms of action to improve glycemic control in patients with type 2 diabetes...

In the last ten years, knowledge on pathophysiology of type 2 diabetes (T2DM) has significantly increased, with multiple failures (decreased incretin effect, increased lipolysis, increased glucagon secretion, neurotransmitters dysfunction) recognized as important contributors, together with decreased insulin secretion and reduced peripheral glucose uptake. As a consequence, the pharmacologic therapy of T2DM has been progressively enriched by several novel classes of drugs, trying to overcome these defects. The last, intriguing compounds come into the market are SGLT2 inhibitors, framing the kidney in a different scenario, not as site of a harmful disease complication, but rather as the means to correct hyperglycemia and fight the disease...

Clinical trials of glucose-lowering strategies in patients with type 2 diabetes mellitus (T2DM) have shown a favorable effect of intensive glycemic control on microvascular complications but failed to show a clear benefit on cardiovascular events. In 2008, the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) have required stringent criteria to approve new glucose-lowering drugs, demanding proof of cardiovascular safety. As a result of these regulatory requirements, a number of cardiovascular outcome trials in T2DM have been conducted examining the cardiovascular safety of novel glucose-lowering drugs...

Diabetes is a leading cause of morbidity and mortality worldwide. Management of diabetes is changing at a rapid pace. Three new classes of antidiabetic drugs including GLP-1 (Glucagon-like peptide 1), DPP-IV (Dipeptidyl peptidase IV) and SGLT2 (Sodium glucose cotransporter 2) inhibitors have been approved in the last few years. Treating diabetes with the antidiabetic drug does not always reduce the cardiovascular complications of diabetes. On the contrary, there was a huge controversy regarding the effect of rosiglitazone on cardiovascular risk reduction a few years ago...

The Na(+)-glucose cotransporter 1 (SGLT1/SLC5A1) is predominantly expressed in the small intestine. It transports glucose and galactose across the apical membrane in a process driven by a Na(+) gradient created by Na(+)-K(+)-ATPase. SGLT2 is the major form found in the kidney, and SGLT2-selective inhibitors are a new class of treatment for type 2 diabetes mellitus (T2DM). Recent data from patients treated with dual SGLT1/2 inhibitors or SGLT2-selective drugs such as canagliflozin (SGLT1 IC50 = 663 nM) warrant evaluation of SGLT1 inhibition for T2DM...
