Canagliflozin: uses, appearance and warnings

INVOKANA (canagliflozin) is indicated: as an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus. to reduce the risk of major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction and nonfatal stroke) in adults with type 2 diabetes mellitus and established cardiovascular disease (CVD). to reduce the risk of end-stage kidney disease (ESKD), doubling of serum creatinine, cardiovascular (CV) death, and hospitalization for heart failure in adults with type 2 diabetes mellitus and diabetic nephropathy with albuminuria greater than 300 mg/day. INVOKANA is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated: As an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus ( 1 ). To reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes mellitus and established cardiovascular disease ( 1 ). To reduce the risk of end-stage kidney disease, doubling of serum creatinine, cardiovascular death, and hospitalization for heart failure in adults with type 2 diabetes mellitus and diabetic nephropathy with albuminuria ( 1 ). Limitations of Use: Not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus ( 1 ). Not recommended for use to improve glycemic control in patients with type 2 diabetes mellitus with an eGFR less than 30 mL/min/1.73 m 2 ( 1 ). Limitations of Use INVOKANA is not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus [see Warnings and Precautions (5.1) ] . INVOKANA is not recommended for use to improve glycemic control in patients with type 2 diabetes mellitus with an eGFR less than 30 mL/min/1.73 m 2 . INVOKANA is likely to be ineffective in this setting based upon its mechanism of action.

INVOKANA is contraindicated in patients with a serious hypersensitivity reaction to INVOKANA, such as anaphylaxis or angioedema [see Warnings and Precautions (5.6) and Adverse Reactions (6.1 , 6.2) ] . Serious hypersensitivity reaction to INVOKANA ( 4 )

Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis : Consider ketone monitoring in patients at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue INVOKANA if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting ( 5.1 ). Lower Limb Amputation : Monitor patients for infections or ulcers of lower limb and institute appropriate treatment ( 5.2 ). Volume Depletion : May result in acute kidney injury. Before initiating INVOKANA, assess and correct volume status in patients with renal impairment, elderly patients, or patients on loop diuretics. Monitor for signs and symptoms during therapy ( 5.3 ). Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene), and Genital Mycotic Infections : Monitor patients for signs and symptoms of genitourinary infections and treat promptly, if indicated. Immediately evaluate patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, for necrotizing fasciitis and if suspected, discontinue INVOKANA, and promptly institute appropriate medical and/or surgical intervention ( 5.4 ). Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues : Consider a lower dose of insulin or the insulin secretagogue to reduce the risk of hypoglycemia when used in combination with INVOKANA ( 5.5 ). Hypersensitivity Reactions : Discontinue INVOKANA and monitor until signs and symptoms resolve ( 5.6 ). Bone Fracture : Consider factors that contribute to fracture risk before initiating INVOKANA ( 5.7 ). 5.1 Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis In patients with type 1 diabetes mellitus, INVOKANA significantly increases the risk of diabetic ketoacidosis, a life-threatening event, beyond the background rate. In placebo-controlled trials of patients with type 1 diabetes mellitus, the risk of ketoacidosis was markedly increased in patients who received sodium glucose transporter 2 (SGLT2) inhibitors compared to patients who received placebo; this risk may be greater with higher doses of INVOKANA. INVOKANA is not indicated for glycemic control in patients with type 1 diabetes mellitus. Type 2 diabetes mellitus and pancreatic disorders (e.g., history of pancreatitis or pancreatic surgery) are also risk factors for ketoacidosis. There have been postmarketing reports of fatal events of ketoacidosis in patients with type 2 diabetes mellitus using SGLT2 inhibitors, including INVOKANA. Precipitating conditions for diabetic ketoacidosis or other ketoacidosis include under-insulinization due to insulin dose reduction or missed insulin doses, acute febrile illness, reduced caloric intake, ketogenic diet, surgery, volume depletion, and alcohol abuse. Signs and symptoms are consistent with dehydration and severe metabolic acidosis and include nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. Blood glucose levels at presentation may be below those typically expected for diabetic ketoacidosis (e.g., less than 250 mg/dL). Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 3 days after discontinuing INVOKANA [see Clinical Pharmacology (12.2) ]; however, there have been postmarketing reports of ketoacidosis and/or glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors. Consider ketone monitoring in patients at risk for ketoacidosis if indicated by the clinical situation. Assess for ketoacidosis regardless of presenting blood glucose levels in patients who present with signs and symptoms consistent with severe metabolic acidosis. If ketoacidosis is suspected, discontinue INVOKANA, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting INVOKANA. Withhold INVOKANA, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. Resume INVOKANA when the patient is clinically stable and has resumed oral intake [see Dosage and Administration (2.5) ] . Educate all patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue INVOKANA and seek medical attention immediately if signs and symptoms occur. 5.2 Lower Limb Amputation An increased risk of lower limb amputations associated with INVOKANA use versus placebo was observed in CANVAS (5.9 vs 2.8 events per 1,000 patient-years) and CANVAS-R (7.5 vs 4.2 events per 1,000 patient-years), two randomized, placebo-controlled trials evaluating adult patients with type 2 diabetes mellitus who had either established cardiovascular disease or were at risk for cardiovascular disease [see Adverse Reactions (6.1) and Clinical Studies (14.3) ]. Amputations of the toe and midfoot (99 out of 140 patients with amputations receiving INVOKANA in the two trials) were the most frequent; however, amputations involving the leg, below and above the knee, were also observed (41 out of 140 patients with amputations receiving INVOKANA in the two trials). Some patients had multiple amputations, some involving both lower limbs. Lower limb infections, gangrene, and diabetic foot ulcers were the most common precipitating medical events leading to the need for an amputation. The risk of amputation was highest in patients with a baseline history of prior amputation, peripheral vascular disease, and neuropathy. Counsel patients about the importance of routine preventative foot care. Monitor patients receiving INVOKANA for signs and symptoms of infection (including osteomyelitis), new pain or tenderness, sores or ulcers involving the lower limbs, and institute appropriate treatment. …

Table 7: Clinically Significant Drug Interactions with INVOKANA UGT Enzyme Inducers Clinical Impact: UGT enzyme inducers decrease canagliflozin exposure which may reduce the effectiveness of INVOKANA. Intervention: For patients with eGFR 60 mL/min/1.73 m 2 or greater, if an inducer of UGTs is administered with INVOKANA, increase the dosage to 200 mg daily in patients currently tolerating INVOKANA 100 mg daily. The total daily dosage may be increased to 300 mg daily in patients currently tolerating INVOKANA 200 mg daily who require additional glycemic control. For patients with eGFR less than 60 mL/min/1.73 m 2 , if an inducer of UGTs is administered with INVOKANA, increase the dosage to 200 mg daily in patients currently tolerating INVOKANA 100 mg daily. …
