Study Notes
Mechanism of Action
- Canagliflozin inhibits SGLT2 in the kidneys, reducing glucose reabsorption and increasing glucose excretion in urine
- Inhibits glucose reabsorption in the proximal tubule, increasing urinary glucose excretion and reducing glucose reabsorption
- Increases GLP-1 and PYY levels, improving beta-cell function and insulin sensitivity
Type 2 Diabetes Management
- Approved for treatment of type 2 diabetes as monotherapy or with other antidiabetic agents
- Reduces HbA1c levels, fasting plasma glucose, and body weight
- Suitable for patients with inadequate glycemic control on diet and exercise, or with metformin, sulfonylureas, pioglitazone, or insulin
- Can be used in patients with established cardiovascular disease or at high risk of cardiovascular disease
Renal Effects
- Increases urinary glucose excretion, leading to osmotic diuresis and increased urine volume
- May cause acute kidney injury due to dehydration and hypovolemia, particularly in patients with pre-existing kidney disease
- Reduces albuminuria and slows progression of kidney disease in patients with diabetic nephropathy
Cardiovascular Benefits
- Reduces major adverse cardiovascular events (MACE) in patients with type 2 diabetes and established cardiovascular disease
- Reduces hospitalization for heart failure and cardiovascular death
- May reduce blood pressure and improve cardiovascular outcomes in patients with type 2 diabetes
Adverse Reactions
- Common adverse reactions include vulvovaginal candidiasis, balanitis, and urinary tract infections
- Increases risk of amputations, particularly of the toe or midfoot
- May cause hypotension, particularly in patients taking diuretics or with underlying kidney disease
- May increase risk of bone fracture, particularly in older adults
Dapagliflozin (Farxiga)
Indications
- Indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus
