What are alternative treatment options for a patient currently taking Empagliflozin (SGLT2 inhibitor) 10mg?

Alternative Options to Empagliflozin 10mg

The most direct alternatives to empagliflozin 10mg are other SGLT2 inhibitors—specifically dapagliflozin 10mg or canagliflozin 100mg—which provide equivalent cardiovascular and renal protection with similar safety profiles. 1

Within-Class SGLT2 Inhibitor Alternatives

Dapagliflozin

• Dapagliflozin 10mg once daily is the preferred within-class substitute, offering identical cardiovascular death or heart failure hospitalization reduction (26% risk reduction) and kidney disease progression benefits (39% reduction in composite renal outcomes) 2, 3
• No dose titration required; fixed 10mg daily dose for cardiovascular and renal protection regardless of diabetes status 2
• Can be initiated if eGFR ≥25 mL/min/1.73 m² (some guidelines allow ≥20 mL/min/1.73 m²) 2, 3
• For glycemic control specifically, start at 5mg daily if eGFR ≥45 mL/min/1.73 m², may increase to 10mg 2

Canagliflozin

• Canagliflozin 100mg once daily is an alternative with proven cardiovascular benefit (14% reduction in 3-point MACE, HR 0.86) 1, 3
• May increase to 300mg daily for additional glycemic control only if eGFR ≥60 mL/min/1.73 m² 1, 3
• Maximum dose limited to 100mg daily if eGFR 45-59 mL/min/1.73 m² 1
• Important caveat: Canagliflozin carries a possible increased risk of lower limb amputations and bone fractures compared to other SGLT2 inhibitors 3, 4

Key Considerations for SGLT2 Inhibitor Selection

• Among SGLT2 inhibitors, empagliflozin was historically preferred based on the strongest evidence from EMPA-REG OUTCOME showing 38% reduction in cardiovascular death 1
• All three agents (empagliflozin, dapagliflozin, canagliflozin) reduce heart failure hospitalization by approximately 33-35% 1
• Glucose-lowering efficacy decreases with declining renal function, but cardiovascular and renal benefits persist at lower eGFR levels 2, 3

Alternative Drug Class: GLP-1 Receptor Agonists

When to Consider GLP-1 RAs Instead

• If eGFR <25 mL/min/1.73 m², switch to a GLP-1 receptor agonist rather than another SGLT2 inhibitor 2
• If the patient requires additional glucose lowering beyond what SGLT2 inhibitors provide, add or switch to a GLP-1 RA 1
• If the patient has recurrent genital mycotic infections or urinary tract infections on SGLT2 inhibitors, consider switching to a GLP-1 RA 1, 3

Preferred GLP-1 RA Options

• Liraglutide 1.8mg daily is the preferred GLP-1 RA for cardiovascular event reduction based on the most convincing data at the time of the 2018 ACC consensus 1
• GLP-1 RAs offer MACE reduction but do not reduce heart failure hospitalization risk like SGLT2 inhibitors 1
• GLP-1 RAs provide greater A1C reduction (typically 1.0-1.5% vs 0.5-0.8% for SGLT2 inhibitors) and more weight loss 1
• Must be up-titrated slowly to maximal tolerated dose, unlike SGLT2 inhibitors which use fixed dosing 1

Clinical Decision Algorithm

For patients with established cardiovascular disease, heart failure, or chronic kidney disease:

1. If eGFR ≥25 mL/min/1.73 m²: Use dapagliflozin 10mg or canagliflozin 100mg as direct empagliflozin replacement 1, 2
2. If eGFR <25 mL/min/1.73 m²: Switch to GLP-1 RA (liraglutide preferred) 1, 2
3. If recurrent genital infections or UTIs: Consider GLP-1 RA instead 1, 3
4. If additional glucose lowering needed beyond SGLT2 inhibitor: Add GLP-1 RA to SGLT2 inhibitor 1

For patients requiring glycemic control without established ASCVD:

• If eGFR ≥45 mL/min/1.73 m²: Any SGLT2 inhibitor at standard doses 1, 3
• If eGFR 30-44 mL/min/1.73 m²: SGLT2 inhibitors have minimal glucose-lowering effect; prefer GLP-1 RA or insulin 2, 3

Important Safety Considerations When Switching

Shared SGLT2 Inhibitor Precautions

• Withhold at least 3 days before major surgery or prolonged fasting to prevent postoperative ketoacidosis 2, 5
• Hold during acute illness with reduced oral intake, fever, vomiting, or diarrhea 2
• Monitor for euglycemic diabetic ketoacidosis (can occur with normal blood glucose) 2, 3, 4
• Genital mycotic infections occur in ~6% vs 1% placebo; higher in women 2, 3
• Assess volume status before initiation; reduce concurrent diuretic doses if needed 2, 5

Specific to Canagliflozin

• Higher risk of lower limb amputations (primarily toe/metatarsal) and bone fractures compared to other SGLT2 inhibitors 3, 4
• Examine feet regularly and avoid in patients with active foot ulcers or high amputation risk 4

Common Pitfalls to Avoid

• Do not discontinue SGLT2 inhibitors solely because eGFR falls below 45 mL/min/1.73 m²—cardiovascular and renal benefits persist even when glycemic efficacy is lost 2, 3
• Do not reduce insulin doses excessively when holding SGLT2 inhibitors during illness—this combination significantly increases ketoacidosis risk 2
• Do not assume all SGLT2 inhibitors are interchangeable for all indications—check FDA-approved indications and specific trial data 1, 3
• An initial eGFR dip of 3-5 mL/min/1.73 m² within 1-4 weeks is expected and reversible; do not discontinue unless accompanied by hypovolemia 2
