c. Delayed the absorption of glucose from gut to blood.
d. Increase gluconeogenesis in the liver.
e. Increase excretion of glucose through kidney.

Answer: (e). 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).

Which of the following drugs interacts with Invokana (Canagliflozin)? [SELECT All THAT APPLY]

a. Digoxin
b. Rifampin
c. Ketoconazole
d. Trazodone
e. Tramadol


Which of the following drugs interacts with Invokana (Canagliflozin)? [SELECT All THAT APPLY]

a. Digoxin
b. Rifampin
c. Ketoconazole
d. Trazodone
e. Tramadol

Answer: (a and b). 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) (Canagliflozin), consider increasing the dose to 300 mg once daily if patients are currently tolerating Invokana (Canagliflozin) 100 mg once daily, have an eGFR greater than 60 mL/min/1.73 m2, and require additional glycemic control.

Consider other antihyperglycemic therapy in patients with an eGFR of 45 to less than 60 mL/min/1.73 m2 receiving concurrent therapy with a UGT inducer and require additional glycemic control.

There was an increase in the AUC and mean peak drug concentration (Cmax) of digoxin (20% and 36%, respectively) when co-administered with Invokana (Canagliflozin) 300 mg. Patients taking Invokana (Canagliflozin) with concomitant digoxin should be monitored appropriately.

e. The most common side effect associated with the use of Invokana is hypoglycemia.

Answer: (a,b,c, and d). Invokana (Canagliflozin) is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

The recommended starting dose is 100 mg once daily, taken before the first meal of the day. Dose can be increased to 300 mg once daily in patients tolerating Invokana (Canagliflozin) 100 mg once daily who have an eGFR of 60 mL/min/1.73 m2 or greater and require additional glycemic control.

Invokana (Canagliflozin) is limited to 100 mg once daily in patients who have an eGFR of 45 to less than 60 mL/min/1.73 m2. Assess renal function before initiating Invokana (Canagliflozin). Do not initiate Invokana (Canagliflozin) if eGFR is below 45 mL/min/1.73 m2. Discontinue Invokana (Canagliflozin) if eGFR falls persistently below 45 mL/min/1.73 m2.

It can increase the risk of hypoglycemia when combined with insulin or an insulin secretagogue. A lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with Invokana (Canagliflozin).

It causes intravascular volume contraction. Symptomatic hypotension can occur after initiating Invokana (Canagliflozin), particularly in patients with impaired renal function (eGFR <60 mL/min/1.73 m2), elderly patients, patients on either diuretics or medications that interfere with the renin‐angiotensin‐aldosterone system, or patients with low systolic blood pressure.

The most common side effects of Invokana (Canagliflozin) include genital yeast infections, urinary tract infection, and changes in urination.
