Description
Drug class
Sodium–Glucose Co-Transporter 2 (SGLT2) inhibitor
Indications
- Type 2 Diabetes Mellitus – to improve glycemic control in adults
- Heart Failure – reduces risk of cardiovascular death and hospitalization in HFrEF (with or without diabetes)
- Chronic Kidney Disease (CKD) – slows progression and reduces risk of cardiovascular events in patients with CKD (with or without diabetes)
Mechanism of Action
- Inhibits SGLT2 in the proximal renal tubules ? reduces reabsorption of filtered glucose and sodium
- Leads to increased urinary glucose excretion ? lowers blood glucose levels
- Also causes mild osmotic diuresis and natriuresis ? beneficial effects on heart failure and kidney outcomes
Dosage
- Type 2 Diabetes: 10 mg orally once daily (can be taken with or without food)
- Heart Failure / CKD: 10 mg once daily
- Renal adjustment:
- eGFR ?45 mL/min/1.73 m² ? No adjustment
- eGFR 25–44 ? May continue for HF or CKD benefit (not recommended for initiating in T2DM solely for glycemic control)
- eGFR <25 ? Not recommended for glycemic control; may continue for HF or CKD
Patient Advice
- Take once daily at the same time
- Maintain good genital hygiene to reduce infection risk
- Stay hydrated, especially in hot weather or during illness
- Report signs of genital pain/swelling, fever, or unexplained nausea/vomiting immediately
- Check ketones if feeling unwell, even if blood glucose is not high
