Sotagliflozin

Sotagliflozin is a dual SGLT2 and SGLT1 inhibitor used for heart failure and diabetes.

Unlike other SGLT2 inhibitors, sotagliflozin also inhibits SGLT1 in the intestine.

SGLT2 Inhibitors Overview


Mechanism of Action

SGLT2 inhibition (kidney):

• Blocks glucose reabsorption in proximal tubule • Causes glucosuria • Causes mild natriuresis • Reduces intraglomerular pressure

SGLT1 inhibition (intestine):

• Reduces postprandial glucose absorption • Blunts post-meal glucose spikes

Net Effects:

• ↓ Blood glucose • Mild osmotic diuresis • ↓ Preload • ↓ Blood pressure • Cardiorenal protection


Indications

Heart Failure ★

Indicated for:

• HFrEF • HFpEF • Worsening heart failure

Benefits:

• ↓ HF hospitalization • ↓ Cardiovascular events • Works with or without diabetes

Heart Failure Module


Type 2 Diabetes Mellitus

• Improves glycemic control • Blunts postprandial glucose rise


Major Trials

SOLOIST-WHF:

• Reduced cardiovascular death and HF events • Studied in patients recently hospitalized for worsening HF

SCORED:

• Reduced cardiovascular events in diabetic patients with CKD


Adverse Effects

Common:

• Genital mycotic infections • Diarrhea (more common due to SGLT1 inhibition) • Volume depletion • Hypotension

Serious (rare):

• Euglycemic DKA • Fournier gangrene


Contraindications / Cautions

• Type 1 diabetes • Severe dehydration • Advanced renal impairment (indication-dependent)

Hold during:

• Acute illness • Surgery • Prolonged fasting

Clinical Pearls

✔ Dual SGLT1 and SGLT2 inhibitor ✔ Reduces HF hospitalization ✔ Useful after recent HF hospitalization ✔ Causes more GI side effects than other gliflozins ✔ Benefit independent of diabetes status
