What is the role of Jardiance (empagliflozin) in treating type 2 diabetes?

Role of Empagliflozin (Jardiance) in Type 2 Diabetes Management

Empagliflozin (Jardiance) is highly recommended for patients with type 2 diabetes, particularly those with established cardiovascular disease, as it significantly reduces cardiovascular mortality by 38% and improves glycemic control while offering renal protection. 1, 2

Indications and Benefits

• Empagliflozin is FDA-approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus 2
• It is also specifically indicated to reduce the risk of cardiovascular death in adult patients with type 2 diabetes mellitus who have established cardiovascular disease 2
• In the landmark EMPA-REG OUTCOME trial, empagliflozin demonstrated a 14% reduction in the composite outcome of myocardial infarction, stroke, and cardiovascular death, and a remarkable 38% reduction in cardiovascular death 1
• Beyond glycemic control, empagliflozin provides significant cardiorenal benefits including reduced hospitalization for heart failure 1

Mechanism of Action and Efficacy

• As an SGLT2 inhibitor, empagliflozin works by blocking glucose reabsorption in the proximal renal tubules, increasing urinary glucose excretion 1
• This insulin-independent mechanism makes it effective regardless of beta-cell function or insulin resistance 1, 3
• Empagliflozin typically reduces HbA1c by approximately 0.5-0.8% compared to placebo in patients with baseline HbA1c around 8% 4, 5
• Additional benefits include modest weight reduction (approximately 2 kg) and blood pressure lowering (systolic ~4 mmHg) 5, 6

Place in Therapy Algorithm

1. First-line therapy: Metformin remains the first-line agent for most patients with type 2 diabetes 1

2. Second-line therapy:

   • For patients with established cardiovascular disease: Add empagliflozin to reduce cardiovascular mortality 1
   • For patients with heart failure (with reduced or preserved ejection fraction): Empagliflozin is strongly recommended regardless of diabetes status 1
   • For patients with chronic kidney disease with albuminuria: Empagliflozin provides renal protection 1

3. Combination therapy: Empagliflozin can be effectively combined with other antidiabetic medications including metformin, sulfonylureas, DPP-4 inhibitors, GLP-1 receptor agonists, and insulin 3, 7

Dosing Considerations

• The recommended starting dose is 10 mg once daily in the morning, with or without food 2
• The dose may be increased to 25 mg daily in patients who tolerate the medication well 2
• Renal function assessment is required before initiation:
  • Do not initiate if eGFR is less than 45 mL/min/1.73 m² 2
  • Discontinue if eGFR persistently falls below 45 mL/min/1.73 m² 2

Safety Profile and Precautions

• Common adverse effects include genital mycotic infections, particularly in women 1, 5

• Rare but serious adverse effects to monitor for include:

  • Diabetic ketoacidosis, which can occur even with only modestly elevated blood glucose 2
  • Volume depletion and hypotension, particularly in elderly patients or those on diuretics 2, 5
  • Urinary tract infections (slight increase in risk) 5

• Empagliflozin is contraindicated in:

  • Patients with severe renal impairment (eGFR <45 mL/min/1.73 m²) 2
  • Patients with history of serious hypersensitivity to empagliflozin 2
  • Patients with type 1 diabetes or for treatment of diabetic ketoacidosis 2

Special Populations

• Elderly patients: Use with caution due to increased risk of volume depletion and hypotension 2
• Renal impairment: Not recommended for initiation in patients with eGFR <45 mL/min/1.73 m² 2
• Cardiovascular disease: Preferred agent due to proven cardiovascular mortality benefit 1
• Heart failure: Beneficial regardless of diabetes status 1
• Pediatric patients: Empagliflozin has been studied in children with type 2 diabetes aged 10-17 years, showing significant A1C reduction 1

Clinical Pearls

• Correct volume depletion before initiating empagliflozin to reduce risk of hypotension 2
• Monitor renal function periodically during treatment 2
• Educate patients about symptoms of genital infections and ketoacidosis 2, 5
• The cardiovascular benefits of empagliflozin appear early (within months) and are largely independent of its glucose-lowering effect 4, 7
• Consider temporary discontinuation during acute illness or procedures that may increase risk of volume depletion or ketoacidosis 2
