Dapagliflozin, sold under the brand names Farxiga (US) and Forxiga (EU) among others, is a medication used to treat type 2 diabetes. [2] [3] [5] It is also used to treat adults with heart failure and chronic kidney disease. [6] [7] [3] It reversibly inhibits sodium-glucose co-transporter 2 (SGLT2) in the renal proximal convoluted tubule to reduce glucose reabsorption and increase urinary glucose excretion. [8]
Common side effects include hypoglycaemia (low blood sugar), urinary tract infections, genital infections, and volume depletion (reduced amount of water in the body). [9] Diabetic ketoacidosis is a common side effect in type 1 diabetic patients. [10] Serious but rare side effects include Fournier gangrene. [11] Dapagliflozin is a sodium-glucose co-transporter-2 (SGLT-2) inhibitor and works by removing sugar from the body with the urine. [2]
It was developed by Bristol-Myers Squibb in partnership with AstraZeneca. It is on the World Health Organization's List of Essential Medicines. [12] In 2021, it was the 187th most commonly prescribed medication in the United States, with more than 2 million prescriptions. [13] [14] Dapagliflozin is available as a generic medication.
Dapagliflozin is used along with diet, exercise, and usually with other glucose lowering medications, to improve glycaemic control in adults with type 2 diabetes and to reduce the risk of hospitalization for heart failure among adults with type 2 diabetes and known cardiovascular disease or other cardiovascular risk factors (including high blood pressure, high cholesterol, and smokers). Dapagliflozin, in addition to other SGLT2-inhibitors, was shown to reduce the rate of decline in kidney function and kidney failure in non-diabetic and type 2 diabetic adults. [15] [16] Dapagliflozin is also considered as an option for people that have type 2 diabetes mellitus and heart failure with reduced ejection fraction with a LVEF <40%. [17] It can be given regardless of current diabetes status, in addition to standard medical therapy. Recent studies have indicated that the use of dapagliflozin and other medications from the SGLT-2 inhibitor class, such as empagliflozin can reduce the risk of worsening HF or death and hospitalization from CVD. [17] [18] All SGLT-2 inhibitors are useful to reduce the risk of hospitalization for heart failure in people with atherosclerotic cardiovascular disease, but a small number of meta-analyses and cohort studies have shown that dapagliflozin is superior to others such as empagliflozin. [19] [20] [21]
In addition, dapagliflozin is indicated for the treatment of adults with heart failure with reduced ejection fraction to reduce the risk of cardiovascular death and hospitalization for heart failure. [6] [7] [3]
In the European Union it is indicated in adults:
In November 2021, the European Medicines Agency (EMA) stated that dapagliflozin should no longer be used to treat type 1 diabetes. [5]
In 2021, the US Food and Drug Administration (FDA) and the EMA expanded the indications for dapagliflozin to include treatment of nondiabetic patients with chronic kidney disease (CKD). [25] [26] Clinical trials had shown the following effects of such a treatment.
The DIAMOND trial (2017-2019) showed in treatment periods of 6 weeks no improvement of excess proteins in the urine (proteinuria), a significant deterioration of the kidney's filtration rate (reversible within 6 weeks after dapagliflozin discontinuation), and a significant mean loss of bodyweight of 1.5 kg. [27] [28]
The DAPA-CKD trial (2017-2020) showed in a median treatment period of 2.4 years of patients who had already been under ACE or ARB therapy that the events of a sustained decline of 50% in the kidney's filtration rate, kidney failure, or death occurred statistically around 8 months later in the treatment group than in the placebo group. In the first 12-16 months of treatment, however, the kidney's filtration rate was worse in the treatment group than in the placebo group, being slightly less negative in the treatment group than in the placebo group only thereafter. [15] [28]
Since dapagliflozin leads to heavy glycosuria (sometimes up to about 70 grams per day), it can lead to rapid weight loss and tiredness. The glucose acts as an osmotic diuretic (this effect is the cause of polyuria in diabetes), which can lead to dehydration. The increased amount of glucose in the urine can also worsen the infections already associated with diabetes, particularly urinary tract infections and thrush (candidiasis). Rarely, use of an SGLT2 drug, including dapagliflozin, is associated with necrotizing fasciitis of the perineum, also called Fournier gangrene. [29]
Dapagliflozin is also associated with hypotensive reactions. Concerns exist that it may increase the risk of diabetic ketoacidosis. [30] A 2017 meta-analysis showed that SGLT-2 inhibitors such as dapagliflozin were not statistically correlated with an increase in diabetic ketoacidosis occurrence in Type II diabetic patients. [31] However, the DEPICT-1 and DEPICT-2 trials showed that dapagliflozin caused additional diabetic ketoacidosis events in the Type I diabetic patients who received dapagliflozin. [32]
Dapagliflozin can cause dehydration, serious urinary tract infections, and genital yeast infections. [6] Elderly people, people with kidney problems, those with low blood pressure, and people on diuretics should be assessed for their volume status and kidney function. [6] People with signs and symptoms of metabolic acidosis or ketoacidosis (acid buildup in the blood) should also be assessed. [6] Dapagliflozin can cause low blood sugar when combined with insulin. [6]
To lessen the risk of developing ketoacidosis (a serious condition in which the body produces high levels of blood acids called ketones) after surgery, the FDA has approved changes to the prescribing information for SGLT2 inhibitor diabetes medicines to recommend they be stopped temporarily before scheduled surgery. Canagliflozin, dapagliflozin, and empagliflozin should each be stopped at least three days before, and ertugliflozin should be stopped at least four days before scheduled surgery. [33]
Symptoms of ketoacidosis include nausea, vomiting, abdominal pain, tiredness, and trouble breathing. [33]
The glucose lowering effect of dapagliflozin starts to diminish in CKD patients with a reduced kidney function (eGFR <45mL/min), and may not be as effective for glycemic control. However, as recent studies have demonstrated a renoprotective effect in reducing kidney function decline, dapagliflozin can still be used to reduce kidney function decline regardless of diabetes status. Therefore, while dapagliflozin can be used in diabetic patients with CKD to prevent kidney function decline, further interventions may be needed for glycaemic control. [15] [34]
The first synthesis of dapaglifloxin was disclosed in a patent filed by Bristol Myers Squibb in 2002. [35]
The two main carbon-containing fragments are combined by the reaction of an aryl lithium with a trimethylsilyl-protected gluconolactone. The trimethylsilyl groups are then removed by treatment with methanesulfonic acid in methanol. This gives an intermediate with an unwanted methoxy group at the anomeric centre, which is removed by reaction with triethylsilane in the presence of boron trifluoride etherate. This route, as well as others developed for the manufacture of the drug, have been reviewed. [36]
Dapagliflozin inhibits subtype 2 of the sodium-glucose transport proteins (SGLT2), which are responsible for at least 90% of the glucose reabsorption in the kidney. Blocking this transporter mechanism causes blood glucose to be eliminated through the urine. [37] In combination with metformin, dapagliflozin at standard treatment dose of 10 mg daily lowered HbA1c by 0.54-0.84% when compared to metformin monotherapy in patients with inadequately controlled type 2 diabetes and normal renal function. [38] [39] [40]
Its protective effects in heart failure is attributed primarily to haemodynamic effects, where SGLT2 inhibitors potently reduce intravascular volume through osmotic diuresis and natriuresis. This consequently may lead to a reduction in preload and afterload, thereby alleviating cardiac workload and improving left ventricular function. [41]
The IC50 for SGLT2 is less than one-thousandth of the IC50 for SGLT1 (1.1 versus 1390 nmol/L), so that the drug does not interfere with intestinal glucose absorption. [42]
Dapagliflozin is the International nonproprietary name (INN), [43] and the United States Adopted Name (USAN). [44]
The fixed-dose combination product, dapagliflozin/metformin extended-release, is called Xigduo XR. [45] [46] [47]
In July 2016, the fixed-dose combination of saxagliptin and dapagliflozin was approved for medical use in the European Union and is sold under the brand name Qtern. [48] The combination drug was approved for medical use in the United States in February 2017, where it also is sold under the brand name Qtern. [49] [50]
In May 2019, the fixed-dose combination of dapagliflozin, saxagliptin, and metformin hydrochloride as extended-release tablets was approved in the United States to improve glycemic control in adults with type 2 diabetes when used in combination with diet and exercise. The FDA granted the approval of Qternmet XR to AstraZeneca. [51] The combination drug was approved for use in the European Union in November 2019, and is sold under the brand name Qtrilmet. [52]
In 2012, the Committee for Medicinal Products for Human Use (CHMP) of the EMA issued a positive opinion on the drug. [3]
Dapagliflozin was found effective in several studies in participants with type 2. [3] The main measure of effectiveness was the level of glycated haemoglobin (HbA1c), which gives an indication of how well blood glucose is controlled. [3]
In two studies involving 840 participants with type 2 diabetes, dapagliflozin when used alone decreased HbA1c levels by 0.66% more than placebo (a dummy treatment) after 24 weeks. [3] In four other studies involving 2,370 participants, adding dapagliflozin to other diabetes medicines decreased HbA1c levels by 0.54–0.68% more than adding placebo after 24 weeks. [3]
In a study involving 814 participants with type 2 diabetes, dapagliflozin used in combination with metformin was at least as effective as a sulphonylurea (another type of diabetes medicines) used with metformin. [3] Both combinations reduced HbA1c levels by 0.52% after 52 weeks. [3]
A long-term study, involving over 17,000 participants with type 2 diabetes, looked at the effects of dapagliflozin on cardiovascular (heart and circulation) disease. [3] The study indicated that dapagliflozin's effects were in line with those of other diabetes medicines that also work by blocking SGLT2. [3]
In two studies involving 1,648 participants with type 1 diabetes whose blood sugar was not controlled well enough on insulin alone, adding dapagliflozin 5 mg decreased HbA1c levels after 24 hours by 0.37% and by 0.42% more than adding placebo. [3]
Dapagliflozin was approved for medical use in the European Union in November 2012. [3] It is marketed in a number of European countries. [53]
Dapagliflozin was approved for medical use in the United States in January 2014. [54] [25]
In 2020, the US FDA expanded the indications for dapagliflozin to include treatment for adults with heart failure with reduced ejection fraction to reduce the risk of cardiovascular death and hospitalization for heart failure. [6] It is the first in this particular drug class, sodium-glucose co-transporter 2 inhibitors, to be approved to treat adults with New York Heart Association's functional class II-IV heart failure with reduced ejection fraction. [6]
The results of the DAPA-HF and DECLARE-TIMI 58 clinical trials demonstrated the efficacy of dapagliflozin compared to placebo in improving survival in adults with heart failure with reduced ejection fraction by 17%. They both showed a reduction in the number of hospitalizations from worsening heart failure, cardiovascular death and all-cause mortality. [55] [56]
The safety and effectiveness of dapagliflozin were evaluated in a randomized, double-blind, placebo-controlled study of 4,744 participants. [6] The average age of participants was 66 years and more participants were male (77%) than female. [6] To determine the drug's effectiveness, investigators examined the occurrence of cardiovascular death, hospitalization for heart failure, and urgent heart-failure visits. [6] Participants were randomly assigned to receive a once-daily dose of either 10 mg of dapagliflozin or a placebo (inactive treatment). [6] After about 18 months, people who received dapagliflozin had fewer cardiovascular deaths, hospitalizations for heart failure, and urgent heart-failure visits than those receiving the placebo. [6]
In July 2020, the FDA granted AstraZeneca a Fast Track Designation in the US for the development of dapagliflozin to reduce the risk of hospitalization for heart failure or cardiovascular death in adults following a heart attack. [57]
In August 2020, detailed results from the Phase III DAPA-CKD trial reportedly showed that dapagliflozin on top of standard of care reduced the composite measure of worsening of renal function or risk of cardiovascular or renal death by 39% compared to placebo (p<0.0001) in patients with chronic kidney disease stages 2–4 and elevated urinary albumin excretion. The results were consistent in patients both with and without type 2 diabetes. [58]
In April 2021, the FDA expanded the indications for dapagliflozin to include reducing the risk of kidney function decline, kidney failure, cardiovascular death, and hospitalization for heart failure in adults with CKD who are at risk of disease progression. [25] The efficacy of dapagliflozin to improve kidney outcomes and reduce cardiovascular death in people with chronic kidney disease was evaluated in a multicenter, double-blind study of 4,304 participants. [25]
In February 2023, the EU approved dapagliflozin for extended use to cover heart failure patients across the full spectrum of left ventricular ejection fraction (LVEF), including those with mildly reduced and preserved ejection fraction. [59] [60]
A generic version of dapagliflozin was approved by the US FDA in February 2022, [61] but cannot be sold until October 2025. [62] [63] A generic version was approved in Canada in May 2023. [64]
In January 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for a generic version of Forxiga, which has been authorized in the EU since November 2012. [65] Dapagliflozin Viatris was approved for medical used in the European Union in March 2023. [4]
A systematic review concluded that dapagliflozin reduced heart failure hospitalization, cardiovascular death, and all-cause mortality in patients with HFrEF (i.e., congestive heart failure) and diabetes. [66]
Metformin, sold under the brand name Glucophage, among others, is the main first-line medication for the treatment of type 2 diabetes, particularly in people who are overweight. It is also used in the treatment of polycystic ovary syndrome. It is sometimes used as an off-label adjunct to lessen the risk of metabolic syndrome in people who take antipsychotics. Metformin is not associated with weight gain and is taken by mouth.
Drugs used in diabetes treat diabetes mellitus by decreasing the glucose level in the blood. With the exception of insulin, most GLP receptor agonists, and pramlintide, all are administered orally and are thus also called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of hypoglycemic drugs, and their selection depends on the nature of diabetes, age, and situation of the person, as well as other factors.
Diabetic nephropathy, also known as diabetic kidney disease, is the chronic loss of kidney function occurring in those with diabetes mellitus. Diabetic nephropathy is the leading causes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) globally. The triad of protein leaking into the urine, rising blood pressure with hypertension and then falling renal function is common to many forms of CKD. Protein loss in the urine due to damage of the glomeruli may become massive, and cause a low serum albumin with resulting generalized body swelling (edema) so called nephrotic syndrome. Likewise, the estimated glomerular filtration rate (eGFR) may progressively fall from a normal of over 90 ml/min/1.73m2 to less than 15, at which point the patient is said to have end-stage renal disease. It usually is slowly progressive over years.
Inhibitors of dipeptidyl peptidase 4 are a class of oral hypoglycemics that block the enzyme dipeptidyl peptidase-4 (DPP-4). They can be used to treat diabetes mellitus type 2.
Saxagliptin, sold under the brand name Onglyza, is an oral hypoglycemic of the dipeptidyl peptidase-4 (DPP-4) inhibitor class. Early development was solely by Bristol-Myers Squibb; in 2007 AstraZeneca joined with Bristol-Myers Squibb to co-develop the final compound and collaborate on the marketing of the drug.
The sodium/glucose cotransporter 2 (SGLT2) is a protein that in humans is encoded by the SLC5A2 gene.
Alogliptin, sold under the brand names Nesina and Vipidia,) is an oral anti-diabetic drug in the DPP-4 inhibitor (gliptin) class. Alogliptin does not decrease the risk of heart attack and stroke. Like other members of the gliptin class, it causes little or no weight gain, exhibits relatively little risk of hypoglycemia, and has relatively modest glucose-lowering activity. Alogliptin and other gliptins are commonly used in combination with metformin in people whose diabetes cannot adequately be controlled with metformin alone.
Remogliflozin etabonate (INN/USAN) is a drug of the gliflozin class for the treatment of non-alcoholic steatohepatitis ("NASH") and type 2 diabetes. Remogliflozin was discovered by the Japanese company Kissei Pharmaceutical and is currently being developed by BHV Pharma, a wholly owned subsidiary of North Carolina, US-based Avolynt, and Glenmark Pharmaceuticals through a collaboration with BHV. In 2002, GlaxoSmithKline (GSK) received a license to use it. From 2002 to 2009, GSK carried out a significant clinical development program for the treatment of type-2 diabetes mellitus in various nations across the world and obesity in the UK. Remogliflozin etabonate's pharmacokinetics, pharmacodynamics, and clinical dose regimens were characterized in 18 Phase I and 2 Phase II investigations. Due to financial concerns, GSK stopped working on remogliflozin and sergliflozin, two further SGLT2 inhibitors that were licensed to the company, in 2009. Remogliflozin was commercially launched first in India by Glenmark in May 2019.
Canagliflozin, sold under the brand name Invokana among others, is a medication used to treat type 2 diabetes. It is used together with exercise and diet. It is not recommended in type 1 diabetes. It is taken by mouth.
Empagliflozin, sold under the brand name Jardiance, among others, is an antidiabetic medication used to improve glucose control in people with type 2 diabetes. It is not recommended for type 1 diabetes. It is taken by mouth.
Dulaglutide, sold under the brand name Trulicity among others, is a medication used for the treatment of type 2 diabetes in combination with diet and exercise. It is also approved in the United States for the reduction of major adverse cardiovascular events in adults with type 2 diabetes who have established cardiovascular disease or multiple cardiovascular risk factors. It is a once-weekly injection.
Gliflozins are a class of drugs in the treatment of type 2 diabetes (T2D). They act by inhibiting sodium/glucose cotransporter 2 (SGLT-2), and are therefore also called SGLT-2 inhibitors. The efficacy of the drug is dependent on renal excretion and prevents glucose from going into blood circulation by promoting glucosuria. The mechanism of action is insulin independent.
Empagliflozin/linagliptin, sold under the brand name Glyxambi, is a fixed-dose combination anti-diabetic medication used to treat type 2 diabetes. It is a combination of empagliflozin and linagliptin. It is taken by mouth.
SGLT2 inhibitors, also called gliflozins or flozins, are a class of medications that inhibit sodium-glucose transport proteins in the nephron, unlike SGLT1 inhibitors that perform a similar function in the intestinal mucosa. The foremost metabolic effect of this is to inhibit reabsorption of glucose in the kidney and therefore lower blood sugar. They act by inhibiting sodium-glucose transport protein 2 (SGLT2). SGLT2 inhibitors are used in the treatment of type 2 diabetes. Apart from blood sugar control, gliflozins have been shown to provide significant cardiovascular benefit in people with type 2 diabetes. As of 2014, several medications of this class had been approved or were under development. In studies on canagliflozin, a member of this class, the medication was found to enhance blood sugar control as well as reduce body weight and systolic and diastolic blood pressure.
Ipragliflozin is a pharmaceutical drug for treatment of type 2 diabetes. Ipragliflozin, jointly developed by Astellas Pharma and Kotobuki Pharmaceutical, was approved in Japan on January 17, 2014, and in Russia on May 22, 2019.
Finerenone, sold under the brand name Kerendia, is a medication used to reduce the risk of kidney function decline, kidney failure, cardiovascular death, non-fatal heart attacks, and hospitalization for heart failure in adults with chronic kidney disease associated with type 2 diabetes. Finerenone is a non-steroidal mineralocorticoid receptor antagonist (MRA). It is taken orally.
Ertugliflozin, sold under the brand name Steglatro, is a medication for the treatment of type 2 diabetes.
Sotagliflozin, sold under the brand name Inpefa among others, is a medication used to reduce the risk of death due to heart failure.
Dapagliflozin/metformin, sold under the brand name Xigduo XR amongst others, is a fixed-dose combination anti-diabetic medication used as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. It is a combination of dapagliflozin and metformin and is taken by mouth. Dapagliflozin/metformin was approved for use in the European Union in January 2014, in the United States in February 2014, and in Australia in July 2014.
Canagliflozin/metformin, sold under the brand name Vokanamet among others, is a fixed-dose combination anti-diabetic medication used for the treatment of type 2 diabetes. It is used in combination with diet and exercise. It is taken by mouth.
