Abstract
BACKGROUND Sodium-glucose cotransporter 2 (SGLT2) inhibitors attenuate incident cardiovascular outcomes, irrespective of baseline GFR, in conservatively managed CKD. As this condition inexorably progresses to demanding KRT, drug withdrawal is supported by the current lack of evidence of safety of SGLT2 inhibitors in dialysis. METHODS This study was a prospective, single-center, open-label trial ( ClinicalTrials.gov identifier: NCT05343078 ) aimed at assessing the pharmacokinetic properties and safety of dapagliflozin in patients with kidney failure on regular dialysis regimens compared with those with type 2 diabetes and age- and sex-matched controls with normal kidney function. Peripheral blood samples were collected from both groups every 30 minutes for 4 hours and again after 48 hours after ingestion of dapagliflozin 10 mg, which occurred immediately before dialysis session initiation in the kidney failure group. This protocol occurred in drug-naïve patients and again after six daily doses of dapagliflozin to assess whether the drug had accumulated. The plasma and dialysate levels of dapagliflozin at each time point were determined by liquid chromatography and used to calculate pharmacokinetics parameters (peak concentration [C max ] and area under the plasma concentration-versus-time curve) for each participant. RESULTS Dapagliflozin C max was 117 and 97.6 ng/ml in the kidney failure and control groups, respectively, whereas the corresponding accumulation ratios were 26.7% and 9.5%. No serious adverse events were reported for either group. Dapagliflozin recovered from dialysate corresponded to 0.10% of the administered dose. CONCLUSIONS In patients with kidney failure on dialysis, dapagliflozin was well tolerated, was slightly dialyzable, and had nonaccumulating pharmacokinetic properties. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER Pharmacokinetics and Dialyzability of Dapagliflozin in Dialysis Patients (DARE-ESKD 1), NCT05343078.

Abstract
Two open-label, randomized, two-period crossover studies were conducted to investigate the pharmacokinetic (PK) properties, safety, and bioequivalence of the test formulation (KD4004), a new fixed-dose combination (FDC) formulation of dapagliflozin and metformin extended release (XR) tablets, relative to the reference formulation (10 mg dapagliflozin/1,000 mg metformin XR FDC tablet) in healthy subjects under fasting (Part A) and fed (Part B) conditions. After giving the dose, serial blood samples were collected for a period of 48 hours. Primary PK parameters (AUC0-t and Cmax) were used to assess bioequivalence between two dapagliflozin/metformin XR (10/1,000 mg) FDC formulations under fed and fasting conditions. Safety and tolerability were also evaluated. Part A and Part B were completed by 32 and 37 subjects, respectively. Bioequivalence of the two FDC formulations of dapagliflozin and metformin XR tablets was established in both the fasted and the fed conditions as the 90% confidence interval of the ratios of adjusted geometric means for AUC0-t and Cmax were contained within the predefined range of 0.800-1.250 bioequivalence criteria. Single-dose administration of dapagliflozin and metformin XR was safe and well tolerated as the two FDC formulations. In conclusion, both FDC formulations of dapagliflozin and metformin XR tablets were bioequivalent in fed and fasted subjects. All treatments were well tolerated. Trial Registration Clinical Research Information Service Identifier: KCT0004026.

Abstract
Type 2 diabetes mellitus (T2DM) agent sodium-glucose co-transporter 2 (SGLT2) inhibitors show special benefits in reducing body weight and heart failure risks. To accelerate clinical development for novel SGLT2 inhibitors, a quantitative relationship among pharmacokinetics, pharmacodynamics, and disease end points (PK/PD/end points) in healthy subjects and patients with T2DM was developed. PK/PD/end point data in published clinical studies for three globally marketed SGLT2 inhibitors (dapagliflozin, canagliflozin, and empagliflozin) were collected according to pre-set criteria. Overall, 80 papers with 880 PK, 27 PD, 848 fasting plasma glucose (FPG), and 1219 hemoglobin A1c (HbA1c) data were collected. A two-compartmental model with Hill's equation was utilized to capture PK/PD profiles. A novel translational biomarker, the change of urine glucose excretion (UGE) from baseline normalized by FPG (ΔUGEc ) was identified to bridge healthy subjects and patients with T2DM with different disease statuses. ΔUGEc was found to have a similar maximum increase with different half-maximal effective concentration values of 56.6, 2310, and 841 mg/mL·h for dapagliflozin, canagliflozin, and empagliflozin respectively. ΔUGEc will change FPG based on linear function. HbA1c profiles were captured by indirect response model. Additional placebo effect was also considered for both end points. The PK/ΔUGEc /FPG/HbA1c relationship was validated internally using diagnostic plots and visual assessment and further validated externally using the fourth globally approved same-in-class drug (ertugliflozin). This validated quantitative PK/PD/end point relationship offers novel insight into long-term efficacy prediction for SGLT2 inhibitors. The novelty identified ΔUGEc could make the comparison of different SGLT2 inhibitors' efficacy characteristics easier, and achieve early prediction from healthy subjects to patients.

Abstract
INTRODUCTION Diabetes is the most common cause of end stage kidney disease. Therapies such as sodium-glucose co-transporter-2 inhibitors have been identified over the last decade as effective oral hypoglycemic agents that also confer additional cardio and kidney protection. Knowledge of their mechanism of action and impact on patients with diabetes and albuminuria is vital in galvanizing prescriber confidence and increasing clinical uptake. AREAS COVERED This manuscript discusses the pathophysiology of diabetic kidney disease, patho-physiological mechanisms for sodium-glucose co-transporter-2 inhibitors, and their impact on patients with Type 2 diabetes mellitus and albuminuric kidney disease. EXPERT OPINION Sodium-glucose co-transporter-2 inhibitors reduce albuminuria with consequent benefits on cardiovascular and kidney outcomes in patients with diabetes and severe albuminuria. Whilst they have been incorporated into guidelines, the uptake of these agents into clinical practice has been slow. Increasing the uptake of these agents into clinical practice is necessary to improve outcomes for the large number of patients with diabetic kidney disease globally.

Abstract
INTRODUCTION Sodium-dependent glucose cotransporter 2 (SGLT2) is a glucose transporter expressed on the proximal tubular cells, where it reabsorbs glucose from the glomerular filtrate. SGLT2 inhibitors (SGLT2is), initially developed as an antidiabetic drug, have recently attracted considerable attention because they have cardiorenal protective effects. Among SGLT2is, dapagliflozin was the first to demonstrate the renoprotective effect in patients with and without diabetes and has been approved for chronic kidney disease (CKD) treatment. AREAS COVERED This review covers the pharmacological characteristics and the clinical efficacy and safety profiles of dapagliflozin, including comparison with other SGLT2is and risk modification strategies. EXPERT OPINION In DAPA-CKD, dapagliflozin reduced the primary outcome (≥50% estimated glomerular filtration rate [eGFR] decline, end-stage kidney disease [ESKD], or renal or cardiovascular [CV] death) by 39% in CKD patients. This beneficial effect was consistent across prespecified subgroups, including those based on the presence of diabetes. Dapagliflozin also decreased the CV composite outcome and all-cause death by 29% and 31%, respectively. Although an increased risk of adverse events such as ketoacidosis and volume depletion has been reported, the robust renal and CV benefits of dapagliflozin are expected to outweigh potential risks. SGLT2is, including dapagliflozin, will constitute the mainstay of CKD treatment.

Abstract
Dapagliflozin base and a commercial dapagliflozin propanediol hydrate cocrystal (DPF-PDHC) were highly hygroscopic and thermally unstable. In this study, to address this limitation, we prepared a novel dapagliflozin di-L-proline cocrystal (DPF-LPC) and evaluated its physicochemical characterization compared with DPF-PDHC. After the preparation of the DPF-LPC-loaded tablet, its dissolution, stability and bioequivalence in beagle dogs and mini-pigs were assessed. DPF-LPC was well prepared with a dapagliflozin base and L-proline in a molar ratio of 1:2. Similar to DPF-PDHC, DPF-LPC was highly lipophilic and crystalline in nature. However, these two cocrystals exhibited different melting points and crystalline structures, indicating their different cocrystal forms. Moreover, DPF-LPC exhibited less hygroscopicity and lower water content than DPF-PDHC. The DPF-LPC-loaded tablet composed of DPF-LPC, Comprecel M102, lactose monohydrate, crospovidone, magnesium stearate, and Opadry (coating) at a weight ratio of 15.6:104.4:100.0:8.0:2.0:7.0, was dissolution-equivalent to the commercial tablet. Moreover, it provided lower impurities than the commercial tablet, indicating its better stability. In the two animals, there were no significant differences in the plasma concentrations, AUC, Cmax, and Tmax values, suggesting that they were bioequivalent. Therefore, the novel DPF-LPC-loaded tablet with excellent stability and bioequivalence may be used as a potential alternative to the commercial DPF-PDHC-loaded tablet.

Abstract
Dapagliflozin, a selective sodium–glucose co-transporter-2 inhibitor, and linagliptin, a competitive, reversible dipeptidyl peptidase-4 inhibitor, are commonly prescribed antidiabetic medications in general clinics. Since there are several merits to combining them in a fixed-dose combination product, this study investigated the pharmacokinetic equivalence between the individual component (IC) and fixed-combination drug product (FCDP) forms of dapagliflozin and linagliptin. A randomized, open-label, single-dose crossover study was conducted. All participants (n = 48) were randomly allocated to group A (period 1: ICs, period 2: FCDP) or group B (period 1: FCDP, period 2: ICs), and each group received either a single dose of IN-C009 (FCDP) or single doses of both dapagliflozin and linagliptin. There was no statistically significant difference found between the pharmacokinetic variables of FCDP and IC. The values of estimated geometric mean ratios and the 90% confidence interval for both maximum concentration and area under the plasma drug concentration–time curve were within the range of 0.8–1.25 for both dapagliflozin and linagliptin. The results of the clinical study demonstrated comparable pharmacokinetic characteristics between IC and FCDP forms of dapagliflozin and linagliptin. The combined use of dapagliflozin and linagliptin was safe and tolerable in both formulations.

Abstract
PURPOSE Henagliflozin is a highly selective and effective sodium glucose co-transporter (SGLT)-2 inhibitor developed for the treatment of patients with type 2 diabetes mellitus (T2DM). This study aimed to investigate the effects of meal intake on the pharmacokinetic properties of henagliflozin, and to understand the excretion pathways of henagliflozin in humans. METHODS In this Phase I, randomized, open-label, single-dose, two-period crossover study, 12 healthy male Chinese volunteers were randomized to receive either henagliflozin 10 mg in the fasted condition followed by henagliflozin 10 mg in the fed condition, or the reverse schedule, with the two administrations separated by a washout period of at least 7 days. Samples of blood, urine, and feces were collected and analyzed for the investigation of the pharmacokinetic profile and excretion pathways in the fasted and fed conditions. Any adverse events that occurred throughout the study were recorded for tolerability assessment. FINDINGS After the administration of a single oral dose of henagliflozin, mean (SD) plasma AUC0-∞ and Cmax were 1200 (274) h · ng/mL and 179 (48.8) ng/mL, respectively, in the fasted state and were decreased to 971 (245) h · ng/mL and 115 (34.2) ng/mL in the fed state. The fed/fasted ratios (90% CIs) of the geometric mean values of Cmax, AUC0-t, and AUC0-∞ were 64% (54%-76%), 80% (76%-85%), and 80% (76%-85%), respectively. The median (range) Tmax was prolonged from 1.5 (1-3) hours in the fasted condition to 2 (1.5-6) hours in the fed condition. Mass-balance testing revealed that henagliflozin was eliminated primarily as the parent drug in feces and as glucuronide metabolites in urine. In the fasted state, the cumulative excretion percentages of the parent drug and its metabolites to dose in feces and urine were 40.6% and 33.9%, respectively. The values in the fed condition were changed to 50.4% and 25.5%, respectively. These findings suggest that postprandial administration decreases the absorption rate and the extent of henagliflozin exposure in humans, but has no effect on the metabolism or elimination of the drug. IMPLICATIONS In the present study, the consumption of a high-fat meal prior to henagliflozin administration was associated with reductions in AUC0-∞ and Cmax of 19.4% and 36.4%, respectively. However, based on the analysis of the pharmacokinetic/pharmacodynamic findings on henagliflozin, this slight change may not have clinical significance. Mass balance of henagliflozin in humans was achieved with ∼75% of the administered dose recovered in excretions within 4 days after administration whether in the fasted or fed state. These findings suggest that henagliflozin tablets can be administered with or without food.

Abstract
Dapagliflozin belongs in the family of sodium-glucose cotransporter 2 (SGLT2) inhibitors and acts by reducing glucose reabsorption in the proximal tubule. The aim of this review is to present the differential pharmacology and clinical utility of dapagliflozin. Dapagliflozin is orally administered, has a long half-life of 12.9 hours and (similar to empagliflozin) is a much weaker SGLT1 inhibitor compared with canagliflozin. Dapagliflozin significantly decreases glycated hemoglobin and fasting glucose levels in patients with type 2 diabetes mellitus (T2DM). The drug improves body weight, blood pressure, uric acid, triglycerides and high-density lipoprotein cholesterol. In the DECLARE-TIMI 58 trial, a large trial of 17,160 T2DM patients with established cardiovascular disease (CVD) or without established CVD but with multiple risk factors, dapagliflozin compared with placebo resulted in a significantly lower rate of the composite outcome of CVD death or hospitalization for heart failure (HHF); this effect was mainly due to a lower rate of HHF in the dapagliflozin group (HR: 0.73; 95%CI: 0.61–0.88), whereas no difference was observed in the rate of CVD death (HR: 0.98; 95%CI: 0.82–1.17). Moreover, dapagliflozin was noninferior to placebo with respect to major adverse CVD events. Dapagliflozin exerts beneficial effects on albuminuria. Additionally, in the DECLARE-TIMI 58 trial it significantly reduced the composite renal endpoint (40% decrease in glomerular filtration rate, end stage renal disease, or renal death) in both patients with established CVD and patients with multiple risk factors (overall HR: 0.53; 95%CI: 0.43–0.66). However dapagliflozin, like the other SGLT2 inhibitors, is associated with an increased risk of genital and urinary tract infections (usually mild mycotic infections) and acute kidney injury in cases of reduced extracellular volume. Dapagliflozin is a useful antidiabetic treatment which also exerts beneficial effects in the management of heart failure and diabetic kidney disease.

Chronopharmacology of dapagliflozin-induced antihyperglycemic effects in C57BL/6J mice. Obes Res Clin Pract 2019; 13:505-510. [PMID: 31466832 DOI: 10.1016/j.orcp.2019.08.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 07/26/2019] [Accepted: 08/02/2019] [Indexed: 01/07/2023]
Abstract
Chronopharmacology is the study of the varying responses of drugs to changes in biological timing and endogenous periodicities. The selective sodium-glucose cotransporter 2 inhibitor, dapagliflozin, is a globally prescribed antihyperglycemic drug. Although dapagliflozin is usually administered once a day, the specific intake time is generally not mentioned. Therefore, this study aimed at investigating the diurnal effects of dapagliflozin on high-fat diet (HFD)-induced obesity in mice. Five-week-old male C57BL/6J mice were fed a normal (control) diet or HFD for 10 weeks. During the last 2 weeks, the mice were administered olive oil/ethanol emulsion or dapagliflozin (1mg/kg, p.o.) in the light or dark phase. At the end of the experiment, the mice were euthanized after an 18h fasting period, and plasma and tissue samples (epididymal white adipose tissues, liver, and kidney) were collected. Dapagliflozin administration in the light phase significantly decreased plasma glucose levels, insulin levels, adipose adipokines, and decreased the size of adipocytes, compared with the HFD group. In contrast, these parameters remained unchanged in the mice treated during the dark phase. Our data therefore suggests that dapagliflozin portrays definite chronopharmacology, which may provide valuable information on the importance of drug administration timing for maximal pharmacological effects.

Abstract
Sodium glucose cotransporter 2 inhibitors (SGLT2i) are the first antidiabetic compounds that effectively reduce heart failure hospitalization and cardiovascular death in type 2 diabetics. Being explicitly designed to inhibit SGLT2 in the kidney, SGLT2i have lately been investigated for their off-target cardiac actions. Here, we review the direct effects of SGLT2i Empagliflozin (Empa), Dapagliflozin (Dapa), and Canagliflozin (Cana) on various cardiac cell types and cardiac function, and how these may contribute to the cardiovascular benefits observed in large clinical trials. SGLT2i impaired the Na+/H+ exchanger 1 (NHE-1), reduced cytosolic [Ca2+] and [Na+] and increased mitochondrial [Ca2+] in healthy cardiomyocytes. Empa, one of the best studied SGLT2i, maintained cell viability and ATP content following hypoxia/reoxygenation in cardiomyocytes and endothelial cells. SGLT2i recovered vasoreactivity of hyperglycemic and TNF-α-stimulated aortic rings and of hyperglycemic endothelial cells. Anti-inflammatory actions of Cana in IL-1β-treated HUVEC and of Dapa in LPS-treated cardiofibroblast were mediated by AMPK activation. In isolated mouse hearts, Empa and Cana, but not Dapa, induced vasodilation. In ischemia-reperfusion studies of the isolated heart, Empa delayed contracture development during ischemia and increased mitochondrial respiration post-ischemia. Direct cardiac effects of SGLT2i target well-known drivers of diabetes and heart failure (elevated cardiac cytosolic [Ca2+] and [Na+], activated NHE-1, elevated inflammation, impaired vasorelaxation, and reduced AMPK activity). These cardiac effects may contribute to the large beneficial clinical effects of these antidiabetic drugs.

Abstract
Saxagliptin and dapagliflozin are individually indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. The bioequivalence of saxagliptin/dapagliflozin 2.5/5 mg and 5/10 mg fixed-dose combination (FDC) tablets compared with coadministration of the individual tablets and the food effect on both strengths of saxagliptin/dapagliflozin FDCs were evaluated in this open-label, randomized, single-dose crossover study. Healthy subjects were randomized to saxagliptin 2.5 mg + dapagliflozin 5 mg fasted, 2.5/5 mg FDC fasted, 2.5/5 mg FDC fed (Cohort 1) or saxagliptin 5 mg + dapagliflozin 10 mg fasted, 5/10 mg FDC fasted, 5/10 mg FDC fed (Cohort 2). Serial blood samples for pharmacokinetics of saxagliptin and dapagliflozin were obtained predose and up to 60 h postdose. Bioequivalence of FDC tablets versus individual components was concluded if the 90% CIs for FDC to individual component geometric mean ratios of C max, AUC 0-T, and AUC inf of both analytes were between 0.80 and 1.25. Seventy-two subjects were randomized; 71 (98.6%) completed the study. Saxagliptin/dapagliflozin 2.5/5 mg and 5/10 mg FDC tablets were bioequivalent to the individual tablets administered concomitantly. Food had no clinically meaningful effect on saxagliptin or dapagliflozin overall systemic exposure. Saxagliptin/dapagliflozin FDC tablets were bioequivalent to coadministration of the individual components in healthy subjects under fasted conditions and food had no clinically meaningful effect on bioavailability.

Abstract
PURPOSE Simplification of therapeutic regimens for patients with type 2 diabetes mellitus can provide convenience that leads to improved compliance. Dapagliflozin/metformin extended-release (XR) fixed-dose combination (FDC) tablets offer the convenience of once-daily dosing. Two pharmacokinetic (PK) studies were conducted to establish bioequivalence for 2 doses of dapagliflozin/metformin XR FDC versus the same dosage of the individual component (IC) tablets in healthy adults. METHODS Two open-label, randomized, 4-period, 4-arm crossover studies were conducted to assess the bioequivalence and PK properties of dapagliflozin and metformin FDCs in healthy subjects under fed and fasting conditions. Participants received single oral doses or once-daily dosing of dapagliflozin/metformin XR (5 mg/500 mg [study 1] or 10 mg/1000 mg [study 2]) for 4 days in an FDC formulation or corresponding strengths of IC tablets. FINDINGS For both of the studies, dapagliflozin and metformin 5 mg/500 mg or 10 mg/1000 mg FDC tablets were bioequivalent to the respective IC tablets. The 90% CIs of the ratio of the adjusted geometric means for all key PK parameters (Cmax, AUC0-T, and AUC0-∞) were contained within the predefined 0.80 to 1.25 range to conclude bioequivalence for both dapagliflozin and metformin. Once-daily dosing to steady state of each FDC tablet had no effect on the PK properties of dapagliflozin or metformin. When the FDCs were administered with a light-fat meal, there was no effect on metformin PK values and only a modest, nonclinically meaningful effect on dapagliflozin PK values. There were no safety or tolerability concerns. IMPLICATIONS Bioequivalence of the FDCs of dapagliflozin/metformin XR and the ICs was established, and no safety issues of clinical concern were raised.

Abstract
Dapagliflozin is a selective and reversible inhibitor of sodium-glucose linked transporter type 2 (SGLT2), which mediates approximately 90% of active renal glucose reabsorption in the early proximal tubule of the kidney. Dapagliflozin significantly reduces glucose reabsorption and decreases serum glucose concentration in an insulin-independent manner. The decrease of glucose reabsorption by dapagliflozin has also been associated with a reduction in body weight. Furthermore, the drug modestly reduces blood pressure levels through weight loss and its action as osmotic diuretic. Dapagliflozin has been approved as monotherapy in patients with type 2 diabetes mellitus (T2DM) who cannot tolerate metformin or in combination with other antidiabetic drugs, with the exception of pioglitazone due to the theoretical increased risk of bladder cancer. The drug should not be prescribed in patients with moderate or severe renal impairment or in patients at risk for developing volume depletion. Dapagliflozin is associated with increased incidence of genital and lower urinary tract infections, but these infections are usually mild to moderate and respond to standard antimicrobial treatment. Based on current evidence, dapagliflozin is a useful drug for patients with T2DM with a favorable safety profile. However, further research regarding the effects of dapagliflozin on cardiovascular outcomes is needed.

Abstract
Although several treatment options are available to reduce hyperglycemia, only about half of individuals with diagnosed diabetes mellitus (DM) achieve recommended glycemic targets. New agents that reduce blood glucose concentrations by novel mechanisms and have acceptable safety profiles are needed to improve glycemic control and reduce the complications associated with type 2 diabetes mellitus (T2DM). The renal sodium-glucose co-transporter 2 (SGLT2) is responsible for reabsorption of most of the glucose filtered by the kidney. Inhibitors of SGLT2 lower blood glucose independent of the secretion and action of insulin by inhibiting renal reabsorption of glucose, thereby promoting the increased urinary excretion of excess glucose. Canagliflozin, dapagliflozin, and empagliflozin are SGLT2 inhibitors approved as treatments for T2DM in the United States, Europe, and other countries. Canagliflozin, dapagliflozin, and empagliflozin increase renal excretion of glucose and improve glycemic parameters in patients with T2DM when used as monotherapy or in combination with other antihyperglycemic agents. Treatment with SGLT2 inhibitors is associated with weight reduction, lowered blood pressure, and a low intrinsic propensity to cause hypoglycemia. Overall, canagliflozin, dapagliflozin, and empagliflozin are well tolerated. Cases of genital infections and, in some studies, urinary tract infections have been more frequent in canagliflozin-, dapagliflozin-, and empagliflozin-treated patients compared with those receiving placebo. Evidence from clinical trials suggests that SGLT2 inhibitors are a promising new treatment option for T2DM.

Abstract
OBJECTIVE Dapagliflozin was the first drug in a class of therapies that took a new approach to glycemic control in adults with type 2 diabetes (T2D). It is an inhibitor of the sodium glucose cotransporter, resident in the proximal nephron, which is responsible for the recovery of filtered glucose back into circulation. Inhibiting this cotransporter reduces glucose recovery, increases glucose excretion, and reduces hyperglycemia. Here, we review some of the literature relating to the action, efficacy, and clinical use of dapagliflozin. MATERIALS AND METHODS A Medline search was conducted within date, animal, and language limits, and relevant papers were selected for review. Conference proceedings were reviewed to obtain up-to-date literature on this drug. Clinical trial websites were reviewed for ongoing studies. RESULTS On average, treatment with dapagliflozin results in improvement in glycated hemoglobin by 0.50%, fasting plasma glucose by 1 mmol/L, weight by 2 kg, body mass index by 1.1%, and systolic/diastolic blood pressure by 4/2 mmHg over 24-52 weeks. The weight benefit is greater when used in association with sulfonylureas. It is generally well tolerated, but comes with an increased risk of genitourinary and urinary tract infections. In addition, it is associated with reversible changes to renal function that need to be explored. Early reports of an association with cancer also need to be carefully monitored. CONCLUSION Dapagliflozin is a useful therapy for adult patients with T2D. It also holds potential for a broader range of patients with T2D (such as the elderly and pediatric populations), as well as those with other forms of diabetes, such as type 1 diabetes. While longer-term outcome studies of safety and efficacy are awaited, dapagliflozin forms a very useful and welcome addition to our armamentarium for managing patients with T2D.

Abstract
INTRODUCTION Inhibitors of sodium-glucose cotransporters type 2 (SGLT2), which increase urinary glucose excretion independently of insulin, are proposed as a novel approach for the management of type 2 diabetes mellitus (T2DM). AREAS COVERED An extensive literature search was performed to analyze the pharmacokinetic characteristics, toxicological issues and safety concerns of SGLT2 inhibitors in humans. This review focuses on three compounds (dapagliflozin, canagliflozin, empagliflozin) with results obtained in healthy volunteers (including drug-drug interactions), patients with T2DM (single dose and multiple doses) and special populations (those with renal or hepatic impairment). EXPERT OPINION The three pharmacological agents share an excellent oral bioavailability, long half-life allowing once-daily administration, low accumulation index and renal clearance, the absence of active metabolites and a limited propensity to drug-drug interactions. No clinically relevant changes in pharmacokinetic parameters were observed in T2DM patients or in patients with mild/moderate renal or hepatic impairment. Adverse events are a slightly increased incidence of mycotic genital and rare benign urinary infections. SGLT2 inhibitors have the potential to reduce several cardiovascular risk factors, and cardiovascular outcome trials are currently ongoing. The best positioning of SGLT2 inhibitors in the armamentarium for treating T2DM is still a matter of debate.

Abstract
INTRODUCTION Despite the availability of many antihypreglycemic agents, many patients with type 2 diabetes (T2DM) fail to achieve the glycemic treatment goal, primarily due to progressive beta-cell dysfunction, and increased risk of hypoglycemia. AREAS COVERED The aim of the present article is to review the efficacy and safety of dapagliflozin , a novel antihyperglycemic drug that lowers the plasma glucose concentration by the inhibition of renal sodium-glucose cotransport, in lowering the plasma glucose concentration and the HbA1c in T2DM patents. This review summarizes the published data about the mechanism of action and clinical efficacy of dapagliflozin in lowering the HbA1c in patients with T2DM. It also discusses additional non-glycemic benefits of dapagliflozin and the safety profile of the drug. EXPERT OPINION Dapagliflozin is effective in lowering the plasma glucose concentration in patients with T2DM with a good safety profile. Because of its unique mechanism of action, dapagliflozin can be utilized in combination with all other antihyperglycemic agents and at all stages of the disease.

Abstract
The use of currently available antihyperglycemic agents can be limited by contraindications; cost; renal and hepatic dosage adjustments; dosing schedules; and adverse effects such as gastrointestinal upset, weight gain, and hypoglycemia. These limitations have led the pharmaceutical industry to identify and pursue alternative therapies. Sodium glucose cotransporter-2 (SGLT-2) inhibitors belong to a new class of diabetes drugs and have a novel mechanism of action. These agents are unique in that they increase glucose excretion, independent of insulin secretion, by inhibiting the renal reabsorption of glucose, inducing glycosuria. To summarize the current evidence for SGLT-2 inhibitor therapy, we reviewed abstracts and published data from human trials evaluating the efficacy and safety of dapagliflozin, canagliflozin, and empagliflozin through February 2013. Data from these trials suggest that SGLT-2 inhibitors are able to lower hemoglobin A1c and fasting blood glucose when used as either monotherapy or combination therapy. Cardiometabolic benefits included a reduction in systolic blood pressure, reduction in triglycerides, and weight loss of up to 3 kg. Common and serious adverse effects including infections, cancer, and pollakiuria were identified and reviewed. Although these agents have generally demonstrated efficacy, the adverse effects associated with dapagliflozin have caused a delay in its regulatory approval. Continued research in this area will determine the risk:benefit ratio of SGLT-2 inhibitor therapy.

Abstract
Dapagliflozin (Forxiga®) is the first in a novel class of glucose-lowering agents known as sodium-glucose co-transporter-2 (SGLT2) inhibitors and is used in the treatment of patients with type 2 diabetes. By inhibiting the transporter protein SGLT2 in the kidneys, dapagliflozin reduces renal glucose reabsorption, leading to urinary glucose excretion and a reduction in blood glucose levels. Unlike oral antidiabetic drugs from several other classes, the efficacy of dapagliflozin is independent of insulin secretion and action. Therefore, when used in combination with other antidiabetic drugs, dapagliflozin provides complementary therapy via its unique mechanism of action. A consistent finding across phase III, randomized, double-blind trials in patients with inadequately controlled type 2 diabetes was that dapagliflozin 5 or 10 mg/day for 24 weeks as monotherapy in previously untreated patients, or as add-on combination therapy with metformin, glimepiride, pioglitazone or insulin-based therapy, significantly reduced both glycosylated haemoglobin values (primary endpoint) and fasting plasma glucose levels compared with placebo. Various randomized trials have also shown improvements in postprandial blood glucose with dapagliflozin monotherapy and combination therapy compared with placebo. In addition, dapagliflozin was noninferior to glipizide, in terms of glycaemic control after 52 weeks, when used as add-on therapy in patients with type 2 diabetes that was inadequately controlled with metformin. In most clinical trials, dapagliflozin was associated with reductions in body weight that were statistically superior to placebo or active comparators. Longer-term extension studies indicate that the efficacy of dapagliflozin is maintained for up to ≈2 years. Dapagliflozin was generally well tolerated in clinical trials of 24 or 52 weeks duration and in extension studies of up to ≈2 years. Events suggestive of genital infections and urinary tract infections occurred more frequently among dapagliflozin than placebo recipients. These adverse events are of special interest because they appear to be related to the mechanism of action of dapagliflozin. Dapagliflozin has a low propensity to cause hypoglycaemia, especially when used alone or in combination with metformin, although the incidence of hypoglycaemic events reported with dapagliflozin in clinical trials varied depending on the background therapy. Longer-term tolerability/safety data with dapagliflozin are awaited with interest. In conclusion, dapagliflozin, with its unique and complementary mechanism of action, appears to be an important addition to the therapeutic options for the management of type 2 diabetes, particularly when used as add-on therapy.

Abstract
This Review covers the rationale, physiological consequences and clinical application of pharmacological sodium-glucose cotransporter 2 (SGLT2) inhibition. In patients with type 2 diabetes mellitus, in whom renal glucose reabsorption might be upregulated, orally active, selective SGLT2 inhibitors improve glycaemic control to a therapeutically useful extent. Chronic administration of several SGLT2 inhibitors dose-dependently lowers HbA(1c) levels by 0.5-1.5% without causing hypoglycaemia. The unique mechanism of action of SGLT2 inhibitors-which does not hinge upon β-cell function or tissue insulin sensitivity-means that they can exert their antihyperglycaemic effects in combination with any other oral antidiabetic drug as well as insulin. Available phase III studies confirm a good tolerability profile. Weight loss owing to urinary calorie leakage may be less than expected, but the negative energy balance offers a valuable clinical benefit. Offloading of sodium can assist blood pressure control. The progressive loss of efficacy in patients with reduced glomerular function will have to be balanced against the possibility of renal protection. The safety issues of genitourinary infections and cancer risk requires careful, proactive monitoring and analysis of robust exposure data, particularly in elderly, frail patients and in patients with impaired kidney function and/or high cardiovascular/cancer risk, who represent an increasing fraction of the population with diabetes mellitus.

Abstract
BACKGROUND The kidney plays an important role in glucose metabolism, and has been considered a target for therapeutic intervention. The sodium-glucose cotransporter type 2 (SGLT2) mediates most of the glucose reabsorption from the proximal renal tubule. Inhibition of SGLT2 leads to glucosuria and provides a unique mechanism to lower elevated blood glucose levels in diabetes. The purpose of this review is to explore the physiology of SGLT2 and discuss several SGLT2 inhibitors which have clinical data in patients with type 2 diabetes. METHODS We performed a PubMed search using the terms "SGLT2" and "SGLT2 inhibitor" through April 10, 2012. Published articles, press releases, and abstracts presented at national and international meetings were considered. RESULTS SGLT2 inhibitors correct a novel pathophysiological defect, have an insulin-independent action, are efficacious with glycosylated hemoglobin reduction ranging from 0.5% to 1.5%, promote weight loss, have a low incidence of hypoglycemia, complement the action of other antidiabetic agents, and can be used at any stage of diabetes. They are generally well tolerated. However, due to side effects, such as repeated urinary tract and genital infections, increased hematocrit, and decreased blood pressure, appropriate patient selection for drug initiation and close monitoring after initiation will be important. Results of ongoing clinical studies of the effect of SGLT2 inhibitors on diabetic complications and cardiovascular safety are crucial to determine the risk-benefit ratio. A recent decision by the Committee for Medicinal Products for Human Use of the European Medicines Agency has recommended approval of dapagliflozin for the treatment of type 2 diabetes as an adjunct to diet and exercise, in combination with other glucose-lowering medicinal products, including insulin, and as a monotherapy for metformin-intolerant patients. Clinical research also remains to be carried out on the long-term effects of glucosuria and other potential effects of SGLT2 inhibitors, especially in view of the observed increase in the incidence of bladder and breast cancer. SGLT2 inhibitors represent a promising approach for the treatment of diabetes, and could potentially be an addition to existing therapies.

Abstract
The prevalence of type 2 diabetes is increasing worldwide. The majority of currently available glucose-lowering agents work via insulin-dependent mechanisms and have significant limitations. Hence, there is a need for newer treatments utilizing novel therapeutic targets. Drugs which inhibit the sodium glucose cotransporter in the renal tubules (SGLT-2 inhibitors), represent a novel class of drugs under development. By inhibiting SGLT-2, they promote increased renal glucose excretion and thereby calorie loss with improved glycemic control and weight loss. Dapagliflozin is most advanced in development of this new drug class and currently undergoing phase 3 trials. In addition to its glucose lowering effect, dapagliflozin appears to have favorable impacts on weight and blood pressure, with low risk of hypoglycemia. However, as with all new treatments, long-term safety is an issue. Clinical trials showed increased risk of genital and possibly urinary infections with dapgliflozin. Furthermore, concerns have arisen regarding a possible increased incidence of breast and bladder cancer in patients on dapagliflozin. However, it needs further investigation to confirm or refute whether these concerns are concrete.
