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...

The glucose-lowering pharmacopeia continues to grow for patients with type 2 diabetes. The latest drug category, the SGLT2 inhibitors reduce glycated hemoglobin concentrations by increasing urinary excretion of glucose. They are used mainly in combination with metformin and other antihyperglycemic agents, including insulin. Their glucose-lowering potency is modest. Advantages include lack of hypoglycemia as a side effect, and mild reduction in blood pressure and body weight. Side effects include increased urinary frequency, owing to their mild diuretic action, symptoms of hypovolemia, genitourinary infections...

Although cardiovascular (CV) mortality is the principal cause of death in individuals with type 2 diabetes (T2DM), reduction of plasma glucose concentration has little effect on CV disease (CVD) risk. Thus, novel strategies to reduce CVD risk in T2DM patients are needed. The recently published BI 10773 (Empagliflozin) Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME) study demonstrated that in T2DM patients with high CVD risk empagliflozin reduced the primary major adverse cardiac event end point (CV death, nonfatal myocardial infarction, nonfatal stroke) by 14%...

Canagliflozin, a selective sodium/glucose cotransporter (SGLT) 2 inhibitor, suppresses the renal reabsorption of glucose and decreases blood glucose level in patients with type 2 diabetes. A characteristic of canagliflozin is its modest SGLT1 inhibitory action in the intestine at clinical dosage. To reveal its mechanism of action, we investigated the interaction of canagliflozin with SGLT1 and SGLT2. Inhibition kinetics and transporter-mediated uptake were examined in human SGLT1- or SGLT2-expressing cells...

AIMS: To evaluate the efficacy and safety of titrated canagliflozin, a sodium glucose co-transporter 2 inhibitor, in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin and sitagliptin. METHODS: In this randomized, double-blind study, patients with T2DM (N = 218) on metformin ≥1500 mg/day and sitagliptin 100 mg received canagliflozin 100 mg or placebo. After 6 weeks, the canagliflozin dose was increased from 100 to 300 mg (or from placebo to matching placebo) if all of the following criteria were met: baseline estimated glomerular filtration rate ≥70 ml/min/1...

BACKGROUND: Both sodium glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP4) inhibitors can be used to treat patients with type 2 diabetes mellitus (T2DM) that is inadequately controlled with insulin therapy, and yet there has been no direct comparison of these two inhibitors. METHODS: We searched MEDLINE, EMBASE, LILACS, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov through June 2015. Randomized controlled trials published in English that compare SGLT2 inhibitor plus insulin (SGLT2i/INS) with placebo plus insulin or DPP4 inhibitor plus insulin (DPP4i/INS) with placebo plus insulin in patients with T2DM were selected...

While the modest reduction in the primary composite outcome of myocardial infarction, stroke or cardiovascular death in the EMPA-REG Outcomes trial was welcome, the 30-40% reductions in heart failure hospitalisation (HFH) and cardiovascular and all-cause deaths in patients treated with empagliflozin were highly impressive and unexpected. In this review, we discuss briefly why cardiovascular endpoint trials for new diabetes agents are required and describe the results of the first four such trials to have reported, as a precursor to understanding why the EMPA-REG Outcomes results came as a surprise...

AIM: To assess the comparative efficacy and safety of sodium-glucose co-transporter-2 (SGLT2) inhibitors in adults with type 2 diabetes. METHODS: We electronically searched randomized controlled trials (≥24 weeks) including canagliflozin, dapagliflozin or empagliflozin that were published up to 3 November 2015. Data were collected on cardiometabolic and safety outcomes and synthesized using network meta-analyses. RESULTS: A total of 38 trials (23 997 participants) were included...

BACKGROUND: Sodium glucose co-transporter 2 (SGLT2) inhibitors lower blood glucose levels in patients with type 2 diabetes mellitus (T2DM) by increasing urinary glucose excretion. This review provides a comprehensive summary of preclinical and clinical data on the effects of the SGLT2 inhibitor canagliflozin on mineral balance and bone. METHODS: Published articles and internal study reports through November 2015 were included. RESULTS: In clinical studies, canagliflozin was not associated with meaningful changes in serum or urine calcium, parathyroid hormone, or vitamin D...

It is possible that SGLT2 inhibitors trigger euglycemic diabetic ketoacidosis in some patients. Possible mechanism of euglycemic DKA induced by SGLT2 inhibitors is illustrated.

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...

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...

BACKGROUND: In patients with type 2 diabetes, sodium-glucose cotransporter-2 (SGLT2) inhibitors are known to reduce glucose concentrations, blood pressure, and weight, but to increase LDL cholesterol and the incidence of urogenital infections. Protection against cardiovascular events has also been reported, as have possible increased risks of adverse outcomes such as ketoacidosis and bone fracture. We aimed to establish the effects of SGLT2 inhibitors on cardiovascular events, death, and safety outcomes in adults with type 2 diabetes, both overall and separately for individual drugs...

Sodium-glucose co-transporter type 2 (SGLT2) inhibitors are a new class of oral anti-diabetic agents with a unique, insulin-independent mode of action. In patients with diabetes who have adequate renal function, SGLT2 inhibitors reduce hyperglycemia by blocking renal glucose reabsorption and increasing urinary glucose excretion. These agents are indicated for the treatment of hyperglycemia in type 2 diabetes mellitus (T2DM), as an adjunct to diet and exercise. In terms of efficacy, they are comparable to most other oral agents, and carry a low risk of hypoglycemia unless combined with sulfonylureas or insulin...

Understanding the role of the kidneys in type 2 diabetes mellitus (T2DM) has taken on an increased importance in recent years with the arrival of sodium-glucose co-transporter 2 (SGLT2) inhibitors - antihyperglycemic agents (AHAs) that specifically target the kidneys. This review includes an update on the physiology of the kidneys, their role in the pathophysiology of T2DM, and the mechanisms implicated in the development and progression of diabetic kidney disease, such as glomerular hyperfiltration and inflammation...

INTRODUCTION: The increasing prevalence of type 2 diabetes mellitus (T2DM) and the eventual need for multiple medications in most patients stimulated the development of new drug classes to reduce plasma glucose levels. The GLP-1 receptor agonists (GLP-1RAs) are established as an option for treatment of T2DM after metformin. They are also effective in reducing body weight but current GLP-1RAs have to be given by subcutaneous injection daily or once weekly. AREAS COVERED: This review focuses on the new GLP-1RAs currently undergoing development, some of which require less frequent subcutaneous administration and others that are being developed in oral formulations that may favor patient adherence...

Diabetic micro- and macroangiopathy are devastating vascular complications that could account for disabilities and high mortality rate in patients with diabetes. Indeed, diabetic nephropathy and retinopathy are the leading causes of end-stage renal failure and acquired blindness, respectively, and atherosclerotic cardiovascular diseases (CVD) accounts for about 60% of death in diabetic subjects. As a result, the average life span of diabetic patients is about 10-15 years shorter than that of non-diabetic subjects...
