**Overdose information** If an overdose occurs, contact the Poison Control Center. Normal supportive measures should be taken, including the removal unabsorbed drug from the gastrointestinal tract, initiating clinical monitoring of the patient, and providing supportive treatment as deemed necessary. Canagliflozin has been removed in very small quantities after a 4-hour hemodialysis session. This drug is likely not dialyzable by peritoneal dialysis. **Pregnancy and lactation** Animal data has demonstrated that canagliflozin may cause adverse renal effects in a growing fetus. Data are insufficient at this time in determining a potential canagliflozin related risk for major birth defects or possible miscarriage in humans. There are known risks, however, of uncontrolled diabetes in pregnancy. Inform female patients taking canagliflozin of the potential risk, which is increased during the second and third trimesters. This drug is not recommended during nursing. **Mutagenesis and carcinogenicity** Canagliflozin was not found to be mutagenic in both metabolically activated and inactivated states in the Ames assay. Canagliflozin showed mutagenicity in laboratory mouse lymphoma assay, but only in the activated state. Canagliflozin was not found to be mutagenic in several _in vivo_ assays performed on rats. The carcinogenic risk of canagliflozin was assessed in 2-year studies completed in both CD1 mice and Sprague-Dawley rats. Canagliflozin was not shown to increase tumor incidence in mouse models given doses less than or equal to 14 times the exposure from a typical 300 mg dose in humans. Despite these negative findings in mice, the incidence of several tumors increased in mice, including Leydig cell tumors, renal tubular adenomas, and adrenal pheochromocytomas.|IDENTIFICATION AND USE: Canagliflozin, an oral inhibitor of sodium/glucose cotransporter 2 (SGLT2) in the kidneys, leads to glucosuria and provides a unique mechanism to lower blood glucose levels in diabetes. HUMAN EXPOSURE AND TOXICITY: Canagliflozin is used for the treatment of type 2 diabetes. This agent lowers blood glucose mainly by increasing urinary glucose excretion through inhibition of sodium glucose co-transporter 2 (SGLT2) in the kidneys. Data derived from randomized clinical trials lasting up to 52 weeks suggest that canagliflozin is generally well tolerated. The most common adverse effects are genital mycotic infections occurring in 11-15% of women exposed to canagliflozin versus 2-4% of those randomized to glimepiride or sitagliptin. In men, corresponding proportions are 8-9% versus 0.5-1%. Urinary tract infections (UTI) are slightly increased (5-7%) with the use of canagliflozin compared with placebo (4%). The risk of hypoglycemia associated with canagliflozin is marginally higher than placebo, but markedly increases when the drug is used in conjunction of insulin or sulfonylureas (SU), in patients with chronic kidney disease (CKD), and in the elderly. Worsening renal function and hyperkalemia may occur in patients using canagliflozin, particularly in patients with underlying CKD. Mild weight loss (mean 2-4 kg) and lowering of blood pressure represent 2 advantages of canagliflozin owing to its osmotic diuretic effect. However, the latter action may lead to postural hypotension and dizziness in susceptible subjects. Another concerning adverse effect of canagliflozin is an average 8% increase in plasma levels of low-density lipoprotein cholesterol (LDL-C) compared with placebo. Adverse effects such as increased urinary frequency, genital mycotic infections, and urinary tract infections may discourage the use of the drug in the elderly patient. ANIMAL STUDIES: The carcinogenicity potential of canagliflozin was evaluated in a 2-year rat study (10, 30, and 100 mg/kg). Rats showed an increase in pheochromocytomas, renal tubular tumors, and testicular Leydig cell tumors. Leydig cell tumors were associated with increased luteinizing hormone levels and pheochromocytomas were most likely related to glucose malabsorption and altered calcium homeostasis. Renal tubular tumors may also have been linked to glucose malabsorption. Canagliflozin did not increase the incidence of tumors in mice dosed at 10, 30, or 100 mg/kg. In a juvenile toxicity study in which canagliflozin was dosed directly to young rats from postnatal day (PND) 21 until PND 90 at doses of 4, 20, 65, or 100 mg/kg, increased kidney weights and a dose-related increase in the incidence and severity of renal pelvic and renal tubular dilatation were reported at all dose levels. Exposure at the lowest dose tested was greater than or equal to 0.5 times the maximum clinical dose of 300 mg. The renal pelvic dilatations observed in juvenile animals did not fully reverse within the 1-month recovery period. Similar effects on the developing kidney were not seen when canagliflozin was administered to pregnant rats or rabbits during the period of organogenesis or during a study in which maternal rats were dosed from gestation day (GD) 6 through PND 21 and pups were indirectly exposed in utero and throughout lactation. Canagliflozin had no effects on the ability of rats to mate and sire or maintain a litter up to the high dose of 100 mg/kg (approximately 14 times and 18 times the 300 mg clinical dose in males and females, respectively), although there were minor alterations in a number of reproductive parameters (decreased sperm velocity, increased number of abnormal sperm, slightly fewer corpora lutea, fewer implantation sites, and smaller litter sizes) at the highest dosage administered. Canagliflozin was not mutagenic with or without metabolic activation in the Ames assay. Canagliflozin was mutagenic in the in vitro mouse lymphoma assay with but not without metabolic activation. Canagliflozin was not mutagenic or clastogenic in an in vivo oral micronucleus assay in rats and an in vivo oral Comet assay in rats.

Inhibitors of sodium-glucose cotransporters type 2 (SGLT2) reduce hyperglycaemia by decreasing renal glucose threshold and thereby increasing urinary glucose excretion. They are proposed as a novel approach for the management of type 2 diabetes mellitus. They have proven their efficacy in reducing glycated haemoglobin, without inducing hypoglycaemia, as monotherapy or in combination with various other glucose-lowering agents, with the add-on value of promoting some weight loss and lowering arterial blood pressure. As they may be used concomitantly with many other drugs, we review the potential drug-drug interactions (DDIs) regarding the three leaders in the class (dapagliglozin, canagliflozin and empagliflozin). Most of the available studies were performed in healthy volunteers and have assessed the pharmacokinetic interferences with a single administration of the SGLT2 inhibitor. The exposure [assessed by peak plasma concentrations (Cmax) and area under the concentration-time curve (AUC)] to each SGLT2 inhibitor tested was not significantly influenced by the concomitant administration of other glucose-lowering agents or cardiovascular agents commonly used in patients with type 2 diabetes. Reciprocally, these medications did not influence the pharmacokinetic parameters of dapagliflozin, canagliflozin or empagliflozin. Some modest changes were not considered as clinically relevant. However, drugs that could specifically interfere with the metabolic pathways of SGLT2 inhibitors [rifampicin, inhibitors or inducers of uridine diphosphate-glucuronosyltransferase (UGT)] may result in significant changes in the exposure of SGLT2 inhibitors, as shown for dapagliflozin and canagliflozin. Potential DDIs in patients with type 2 diabetes receiving chronic treatment with an SGLT2 inhibitor deserve further attention, especially in individuals treated with several medications or in more fragile patients with hepatic and/or renal impairment.|Digoxin: There was an increase in the AUC and mean peak drug concentration (C max) of digoxin (20% and 36%, respectively) when co-administered with INVOKANA 300 mg. Patients taking INVOKANA with concomitant digoxin should be monitored appropriately.|Concomitant use of canagliflozin with drugs that interfere with the renin-angiotensin-aldosterone system, including angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor antagonists, may increase the incidence of symptomatic hypotension. Prior to initiating canagliflozin in such patients, intravascular volume should be assessed and corrected; patients should be monitored for signs and symptoms of hypotension after initiating therapy. These drugs also may cause hyperkalemia in patients with moderate renal impairment. Serum potassium concentrations should be monitored periodically following initiation of canagliflozin in patients predisposed to hyperkalemia due to drug therapy.|UGT Enzyme Inducers: Rifampin: Co-administration of canagliflozin with rifampin, a nonselective inducer of several UGT enzymes, including UGT1A9, UGT2B4, decreased canagliflozin area under the curve (AUC) by 51%. This decrease in exposure to canagliflozin may decrease efficacy. If an inducer of these UGTs (e.g., rifampin, phenytoin, phenobarbital, ritonavir) must be co-administered with INVOKANA (canagliflozin), consider increasing the dose to 300 mg once daily if patients are currently tolerating INVOKANA 100 mg once daily, have an eGFR greater than 60 mL/min/1.73 m squared, and require additional glycemic control. Consider other antihyperglycemic therapy in patients with an eGFR of 45 to less than 60 mL/min/1.73 m squared receiving concurrent therapy with a UGT inducer and require additional glycemic control|For more Interactions (Complete) data for Canagliflozin (6 total), please visit the HSDB record page.

Contraindicated in patients with severe renal impairment (eGFR less than 30 mL/min/1.73 sq m), end stage renal disease (ESRD), or patients on dialysis.

Canagliflozin is mainly bound to albumin. The plasma protein binding of this drug is 99%.

Canagliflozin's production and administration as a medication(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 6.9X10+4(SRC), determined from a structure estimation method(2), indicates that canagliflozin is expected to be immobile in soil(SRC). Volatilization of canagliflozin from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.0X10-16 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Canagliflozin is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.1X10-18 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Biodegradation data in soil were not available(SRC, 2015).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 6.9X10+4(SRC), determined from a structure estimation method(2), indicates that canagliflozin is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 1.0X10-16 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 120(SRC), from an estimated log Kow of 4.05(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Biodegradation data in water were not available(SRC, 2015).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), canagliflozin, which has an estimated vapor pressure of 1.1X10-18 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase canagliflozin may be removed from the air by wet and dry deposition(SRC). Canagliflozin does not contain chromophores that absorb at wavelengths >290 nm(3) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

Canagliflozin is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(1). Canagliflozin does not contain chromophores that absorb at wavelengths >290 nm(1) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 120 was calculated in fish for canagliflozin(SRC), using an estimated log Kow of 4.05(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of canagliflozin can be estimated to be 6.9X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that canagliflozin is expected to be immobile in soil.

The Henry's Law constant for canagliflozin is estimated as 1.0X10-16 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that canagliflozin is expected to be essentially nonvolatile from water surfaces(2). Canagliflozin is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.1X10-18 mm Hg(SRC), determined from a fragment constant method(3).

Occupational exposure to canagliflozin may occur through inhalation and dermal contact with this compound at workplaces where canagliflozin is produced or used. Use data indicate that the general population may be exposed to canagliflozin via administration of this drug in treating Type II diabetes. (SRC)

This drug is used in conjunction with diet and exercise to increase glycemic control in adults diagnosed with type 2 diabetes mellitus. Another indication for canagliflozin is the prevention of major cardiovascular events (myocardial infarction, stroke, or death due to a cardiovascular cause) in patients with type 2 diabetes, as well as hospitalization for heart failure in patients with type 2 diabetes[L5897,. In addition to the above, canagliflozin can be used to lower the risk of end-stage kidney disease and major increases in serum creatinine and cardiovascular death for patients with a combination of type 2 diabetes mellitus, diabetic nephropathy, and albuminuria. It is important to note that this drug is **not** indicated for the treatment of type 1 diabetes mellitus or diabetic ketoacidosis.|FDA Label|Vokanamet is indicated in adults aged 18 years and older with type 2 diabetes mellitus as an adjunct to diet and exercise to improve glycaemic control:in patients not adequately controlled on their maximally tolerated doses of metformin alonein patients on their maximally tolerated doses of metformin along with other glucose lowering medicinal products including insulin, when these do not provide adequate glycaemic control.in patients already being treated with the combination of canagliflozin and metformin as separate tabletsFor study results with respect to combination of therapies, effects on glycaemic control and cardiovascular events, and the populations studied, see sections 4.4, 4.5 and 5.1.|Invokana is indicated for the treatment of adults with insufficiently controlled type 2 diabetes mellitus as an adjunct to diet and exercise:as monotherapy when metformin is considered inappropriate due to intolerance or contraindicationsin addition to other medicinal products for the treatment of diabetes.For study results with respect to combination of therapies, effects on glycaemic control, cardiovascular and renal events, and the populations studied, see sections 4.4, 4.5 and 5.1.|Treatment of type II diabetes mellitus

Its selective inhibition, accordingly, leads to substantial glycosuria, lowering blood glucose, and facilitating weight loss in individuals with diabetes. During the past year, two SGLT2 inhibitors, canagliflozin and dapagliflozin, have been approved for the treatment of type 2 diabetes. Beyond their anti-hyperglycemic properties, however, this new class of drugs has several other attributes that provide a theoretical basis for kidney protection. Like agents that block the renin-angiotensin system, SGLT2 inhibitors also reduce single-nephron glomerular filtration rate (SNGFR) in the chronically diseased kidney, though by quite different mechanisms. Additional potentially beneficial effects of SGLT2 inhibition include modest reductions in blood pressure and plasma uric acid. Finally, cell culture studies indicate that glucose uptake from the tubular lumen, as well as from the basolateral compartment, can contribute to proximal tubular production of extracellular matrix proteins. Whether such attributes will translate into reducing the progression of chronic kidney disease will require the undertaking of long-term, dedicated studies.|EXPL THER Management of hypertension in diabetes is critical for reduction of cardiovascular mortality and morbidity. While blood pressure (BP) control has improved over the past two decades, the control rate is still well below 50% in the general population of patients with type 2 diabetes mellitus (T2DM). A new class of oral glucose-lowering agents has recently been approved; the sodium-glucose co-transporter 2 (SGLT2) inhibitors, which act by eliminating large amounts of glucose in the urine. Two agents, dapagliflozin and canagliflozin, are currently approved in the United States and Europe, and empagliflozin and ipragliflozin have reported Phase 3 trials. In addition to glucose lowering, SGLT2 inhibitors are associated with weight loss and act as osmotic diuretics, resulting in a lowering of BP. While not approved for BP-lowering, they may potentially aid BP goal achievement in people within 7-10 mm Hg of goal.

Hypersensitivity reactions (e.g., generalized urticaria), some serious, have been reported with canagliflozin treatment. These reactions generally occurred within hours to days of canagliflozin initiation. If a hypersensitivity reaction occurs, the drug should be discontinued, appropriate treatment instituted, and the patient monitored until signs and symptoms resolve.|Dose-dependent increases in low-density lipoprotein (LDL)-cholesterol can occur during canagliflozin therapy. Serum LDL-cholesterol concentrations should be monitored during treatment with canagliflozin and such lipid elevations treated according to the standard of care.|When canagliflozin is added to therapy with an insulin secretagogue (e.g., a sulfonylurea) or insulin, the incidence of hypoglycemia is increased compared with sulfonylurea or insulin monotherapy. Therefore, patients receiving canagliflozin may require a reduced dosage of the concomitant insulin secretagogue or insulin to reduce the risk of hypoglycemia.|Canagliflozin may increase the risk of genital mycotic infections in males (e.g., balanoposthitis, candidal balanitis) and females (e.g., vulvovaginal candidiasis, vulvovaginal mycotic infection, vulvovaginitis). In clinical trials, patients with a history of genital mycotic infections and uncircumcised males were more likely to develop such infections. Patients should be monitored for genital mycotic infections and appropriate treatment should be instituted if these infections occur.|For more Drug Warnings (Complete) data for Canagliflozin (14 total), please visit the HSDB record page.

This drug increases urinary glucose excretion and decreases the renal threshold for glucose (RTG) in a dose-dependent manner. The renal threshold is defined as the lowest level of blood glucose associated with the appearance of detectable glucose in the urine. The end result of canagliflozin administration is increased urinary excretion of glucose and less renal absorption of glucose, decreasing glucose concentration in the blood and improving glycemic control. **A note on type 2 diabetes and cardiovascular disease** The risk of cardiovascular events in diabetes type 2 is increased due to the damaging effects of diabetes on blood vessels and nerves in the cardiovascular system. In particular, there is a tendency for hyperglycemia to create pro-atherogenic (plaque forming) lesions in blood vessels, leading to various fatal and non-fatal events including stroke and myocardial infarction. Long-term glycemic control has been proven to be effective in the prevention of cardiovascular events such as myocardial infarction and stroke in patients with type 2 diabetes.

**Bioavailability and steady-state** The absolute oral bioavailability of canagliflozin, on average, is approximately 65%. Steady-state concentrations are achieved after 4 to 5 days of daily dose administration between the range of 100mg to 300mg. **Effect of food on absorption** Co-administration of a high-fat meal with canagliflozin exerted no appreciable effect on the pharmacokinetic parameters of canagliflozin. This drug may be administered without regard to food. Despite this, because of the potential of canagliflozin to decrease postprandial plasma glucose excretion due to prolonged intestinal glucose absorption, it is advisable to take this drug before the first meal of the day.|After a single oral radiolabeled dose canagliflozin dose to healthy subjects, the following ratios of canagliflozin or metabolites were measured in the feces and urine: **Feces** 41.5% as the unchanged radiolabeled drug 7.0% as a hydroxylated metabolite 3.2% as an O-glucuronide metabolite **Urine** About 33% of the ingested radiolabled dose was measured in the urine, generally in the form of O-glucuronide metabolites. Less than 1% of the dose was found excreted as unchanged drug in urine.|This drug is extensively distributed throughout the body. On average, the volume of distribution of canagliflozin at steady state following a single intravenous dose in healthy patients was measured to be 83.5 L.|In healthy subjects, canagliflozin clearance was approximately 192 mL/min after intravenous (IV) administration. The renal clearance of 100 mg and 300 mg doses of canagliflozin was measured to be in the range of 1.30 - 1.55 mL/min.|/MILK/ Canagliflozin is distributed into milk in rats; it is not known whether the drug is distributed into human milk.|Canagliflozin is an oral antihyperglycemic agent used for the treatment of type 2 diabetes mellitus. It blocks the reabsorption of glucose in the proximal renal tubule by inhibiting the sodium-glucose cotransporter 2. This article describes the in vivo biotransformation and disposition of canagliflozin after a single oral dose of [(14)C]canagliflozin to intact and bile duct-cannulated (BDC) mice and rats and to intact dogs and humans. Fecal excretion was the primary route of elimination of drug-derived radioactivity in both animals and humans. In BDC mice and rats, most radioactivity was excreted in bile. The extent of radioactivity excreted in urine as a percentage of the administered [(14)C]canagliflozin dose was 1.2%-7.6% in animals and approximately 33% in humans. The primary pathways contributing to the metabolic clearance of canagliflozin were oxidation in animals and direct glucuronidation of canagliflozin in humans. Unchanged canagliflozin was the major component in systemic circulation in all species. In human plasma, two pharmacologically inactive O-glucuronide conjugates of canagliflozin, M5 and M7, represented 19% and 14% of total drug-related exposure and were considered major human metabolites. Plasma concentrations of M5 and M7 in mice and rats from repeated dose safety studies were lower than those in humans given canagliflozin at the maximum recommended dose of 300 mg. However, biliary metabolite profiling in rodents indicated that mouse and rat livers had significant exposure to M5 and M7. Pharmacologic inactivity and high water solubility of M5 and M7 support glucuronidation of canagliflozin as a safe detoxification pathway.|The mean absolute oral bioavailability of canagliflozin is approximately 65%. Co-administration of a high-fat meal with canagliflozin had no effect on the pharmacokinetics of canagliflozin; therefore, INVOKANA may be taken with or without food. However, based on the potential to reduce postprandial plasma glucose excursions due to delayed intestinal glucose absorption, it is recommended that INVOKANA be taken before the first meal of the day. The mean steady-state volume of distribution of canagliflozin following a single intravenous infusion in healthy subjects was 119 L, suggesting extensive tissue distribution. Canagliflozin is extensively bound to proteins in plasma (99%), mainly to albumin. Protein binding is independent of canagliflozin plasma concentrations. Plasma protein binding is not meaningfully altered in patients with renal or hepatic impairment. Following administration of a single oral [14C] canagliflozin dose to healthy subjects, 41.5%, 7.0%, and 3.2% of the administered radioactive dose was recovered in feces as canagliflozin, a hydroxylated metabolite, and an O-glucuronide metabolite, respectively. Enterohepatic circulation of canagliflozin was negligible. Approximately 33% of the administered radioactive dose was excreted in urine, mainly as O-glucuronide metabolites (30.5%). Less than 1% of the dose was excreted as unchanged canagliflozin in urine. Renal clearance of canagliflozin 100 mg and 300 mg doses ranged from 1.30 to 1.55 mL/min. Mean systemic clearance of canagliflozin was approximately 192 mL/min in healthy subjects following intravenous administration.

Canagliflozin is primarily metabolized by O-glucuronidation. It is mainly glucuronidated by UGT1A9 and UGT2B4 enzymes to two inactive O-glucuronide metabolites. The oxidative metabolism of canagliflozin by hepatic cytochrome enzyme CYP3A4 is negligible (about 7%) in humans.|O-glucuronidation is the major metabolic elimination pathway for canagliflozin, which is mainly glucuronidated by UGT1A9 and UGT2B4 to two inactive O-glucuronide metabolites. CYP3A4-mediated (oxidative) metabolism of canagliflozin is minimal (approximately 7%) in humans.

In a clinical study, the terminal half-life of canagliflozin was 10.6 hours for the 100mg dose and 13.1 hours for the 300 mg dose.

The sodium-glucose co-transporter2 (SGLT2), is found in the proximal tubules of the kidney, and reabsorbs filtered glucose from the renal tubular lumen. Canagliflozin inhibits the SGLT2 co-transporter. This inhibition leads to lower reabsorption of filtered glucose into the body and decreases the renal threshold for glucose (RTG), leading to increased glucose excretion in the urine.|Sodium-glucose co-transporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RTG), and thereby increases urinary glucose excretion (UGE).

/OTHER TOXICITY INFORMATION/ Renal hyperfiltration has been used as a surrogate marker for increased intraglomerular pressure in patients with diabetes mellitus. Previous human investigation examining the pathogenesis of hyperfiltration has focused on the role of neurohormones such as the renin-angiotensin-aldosterone system (RAAS). Unfortunately, RAAS blockade does not completely attenuate hyperfiltration or diabetic kidney injury. More recent work has therefore investigated the contribution of renal tubular factors, including the sodium-glucose cotransporter, to the hyperfiltration state, which is the topic of this review. Novel sodium-glucose cotransporter-2 (SGLT2) inhibitors reduce proximal tubular sodium reabsorption, thereby increasing distal sodium delivery to the macula densa, causing tubuloglomerular feedback, afferent vasoconstriction and decreased hyperfiltration in animals. In humans, SGLT2 inhibition was recently shown to reduce hyperfiltration in normotensive, normoalbuminuric patients with type 1 diabetes. In clinical trials of type 2 diabetes, SGLT2 is associated with significant renal effects, including modest, acute declines in estimated glomerular filtration rate followed by the maintenance of stable renal function, and reduced albuminuria.|/OTHER TOXICITY INFORMATION/ In type 2 diabetes (T2DM), glycemic control delays the development and slows the progression of complications. Although there are numerous glucose-lowering agents in clinical use, only approximately half of T2DM patients achieve glycaemic control, while undesirable side-effects, such as hypoglycaemia and body weight gain, often impede treatment in those taking these medications. Thus, there is a need for novel agents and treatment options. Sodium-glucose cotransporter-2 inhibitors (SGLT-2-i) have recently been developed for the treatment of T2DM. The available data suggest a good tolerability profile for the three available drugs - canagliflozin, dapagliflozin and empagliflozin - approved by the US Food and Drug Administration (FDA) for the American market as well as in other countries. The most frequently reported adverse events with SGLT-2-i are female genital mycotic infections, urinary tract infections and increased urination. The pharmacodynamic response to SGLT-2-i declines with increasing severity of renal impairment, requiring dosage adjustments or restrictions with moderate-to-severe renal dysfunction. Most patients treated with SGLT-2-i also have a modest reduction in blood pressure and modest effects on serum lipid profiles, some of which are beneficial (increased high-density lipoprotein cholesterol and decreased triglycerides) and others which are not (increased low-density lipoprotein cholesterol, LDL-C). A number of large-scale and longer-term cardiovascular trials are now ongoing. In patients treated with dapagliflozin, a non-significant excess number of breast and bladder cancers has been reported; considered as due to a bias, this is nevertheless being followed in the ongoing trials. No other significant safety issues have been reported so far.|/OTHER TOXICITY INFORMATION/ Type 2 diabetes mellitus continues to be a challenging disease to manage successfully. Beyond the first-line option metformin, there are a number of classes of medications from which to select. This article reviews the new sodium-glucose cotransporter 2 inhibitors canagliflozin and dapagliflozin, including their benefits, adverse effects, and potential place in therapy. Upon review, the use of these medications has led to an A1c reduction between -0.37% and -1.16%. These medications also have been shown to reduce A1c when used with insulin. Some adverse effects were noted when using canagliflozin and dapagliflozin, with the most frequent being urinary tract infections and genital mycotic infections.
