Pharmacology

🔬

Mechanism of Action

Dapagliflozin is a highly potent, selective, and reversible inhibitor of sodium-glucose co-transporter 2 (SGLT2). SGLT2 is expressed in the proximal renal tubules and is responsible for the reabsorption of approximately 90% of filtered glucose from the tubular lumen. By inhibiting SGLT2, dapagliflozin reduces glucose reabsorption, leading to increased urinary glucose excretion (glucosuria) and a reduction in blood glucose levels. This mechanism is independent of insulin secretion and insulin sensitivity. Additionally, SGLT2 inhibition leads to osmotic diuresis, natriuresis, and a reduction in blood pressure, which contribute to its cardiovascular and renal benefits.

🆘

Overdose Information

Overdose Symptoms:

  • Hypoglycemia (if taken with insulin or sulfonylureas)
  • Volume depletion (dehydration, hypotension)
  • Increased urinary glucose excretion

What to Do:

In case of overdose, contact a poison control center immediately (Call 1-800-222-1222). Treatment is supportive. Monitor for hypoglycemia and volume depletion and manage as appropriate.

Drug Interactions

🟡

Moderate Interactions

  • Diuretics (e.g., loop diuretics, thiazide diuretics): Increased risk of dehydration and hypotension.
  • Insulin and Insulin Secretagogues (e.g., sulfonylureas): Increased risk of hypoglycemia when used concomitantly with dapagliflozin. A lower dose of insulin or insulin secretagogue may be required.
  • Lithium: SGLT2 inhibitors may decrease serum lithium concentrations due to increased urinary sodium excretion. Monitor lithium levels.

Monitoring

🔬

Baseline Monitoring

Renal function (eGFR)

Rationale: To assess baseline kidney function and guide dosing, as dapagliflozin efficacy is dependent on renal function and it is contraindicated in severe renal impairment/dialysis.

Timing: Prior to initiation

Electrolytes (e.g., sodium, potassium)

Rationale: To assess baseline electrolyte status, especially in patients at risk for volume depletion or on diuretics.

Timing: Prior to initiation

Glycated Hemoglobin (HbA1c)

Rationale: To establish baseline glycemic control for patients with Type 2 Diabetes Mellitus.

Timing: Prior to initiation

📊

Routine Monitoring

Renal function (eGFR)

Frequency: At least annually, or more frequently in patients with impaired renal function or those receiving concomitant medications that affect renal function.

Target: Maintain eGFR ≥ 25 mL/min/1.73 m² for continuation.

Action Threshold: Discontinue if eGFR persistently falls below 25 mL/min/1.73 m².

Electrolytes

Frequency: Periodically, especially in patients at risk for volume depletion (e.g., elderly, those on diuretics).

Target: Within normal limits.

Action Threshold: Address imbalances, consider dose adjustment of diuretics or dapagliflozin.

Blood Glucose (Fasting Plasma Glucose, HbA1c)

Frequency: HbA1c every 3-6 months for T2DM; daily self-monitoring of blood glucose as needed.

Target: Individualized glycemic targets.

Action Threshold: Adjust antidiabetic therapy if targets not met or if hypoglycemia occurs.

Signs and symptoms of volume depletion

Frequency: Routinely, especially during initiation or dose titration.

Target: Not applicable.

Action Threshold: If symptoms occur (e.g., dizziness, orthostatic hypotension), assess hydration status and consider temporary interruption or dose reduction.

👁️

Symptom Monitoring

  • Signs and symptoms of dehydration (dizziness, lightheadedness, orthostatic hypotension)
  • Symptoms of urinary tract infection (dysuria, frequent urination, urgency, fever)
  • Symptoms of genital mycotic infection (itching, redness, discharge)
  • Symptoms of diabetic ketoacidosis (nausea, vomiting, abdominal pain, rapid breathing, unusual fatigue, fruity breath odor)
  • Symptoms of Fournier's gangrene (pain, tenderness, erythema, swelling in the genital or perineal area, fever, malaise)
  • Symptoms of hypoglycemia (sweating, tremor, confusion, hunger, irritability) if used with insulin or sulfonylureas

Special Patient Groups

🤰

Pregnancy

Not recommended during the second and third trimesters of pregnancy due to potential adverse effects on renal development in the fetus. Limited data on first trimester use. Discuss risks and benefits with a healthcare provider.

Trimester-Specific Risks:

First Trimester: Limited human data; animal studies do not indicate direct developmental toxicity at clinically relevant exposures.
Second Trimester: Potential for adverse renal developmental effects in the fetus (due to SGLT2 inhibition affecting fluid and electrolyte homeostasis).
Third Trimester: Potential for adverse renal developmental effects in the fetus (due to SGLT2 inhibition affecting fluid and electrolyte homeostasis).
🤱

Lactation

Not recommended during breastfeeding. It is unknown if dapagliflozin is excreted in human milk. Due to the potential for serious adverse reactions in a breastfed infant (e.g., renal developmental effects), a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Infant Risk: Potential for serious adverse reactions (e.g., renal developmental effects, hypoglycemia).
👶

Pediatric Use

Safety and effectiveness have not been established in pediatric patients under 18 years of age for any indication (Type 2 Diabetes Mellitus, Heart Failure, Chronic Kidney Disease).

👴

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly (≥65 years) and younger patients. However, elderly patients may be at increased risk for volume depletion and renal impairment. Monitor renal function and hydration status more frequently.

Clinical Information

💎

Clinical Pearls

  • Dapagliflozin offers benefits beyond glycemic control, including significant reductions in cardiovascular death and hospitalization for heart failure, and progression of kidney disease, independent of diabetes status.
  • Patients should be advised to maintain adequate hydration to minimize the risk of volume depletion, especially during periods of illness, hot weather, or increased physical activity.
  • Educate patients on the symptoms of diabetic ketoacidosis (DKA), even if blood glucose levels are not significantly elevated (euglycemic DKA), and to seek immediate medical attention if symptoms occur.
  • Emphasize the importance of good personal hygiene to reduce the risk of genital mycotic infections.
  • Renal function should be assessed before initiating therapy and periodically thereafter, as efficacy is dependent on eGFR and the drug is contraindicated in severe renal impairment or dialysis.
🔄

Alternative Therapies

  • Other SGLT2 inhibitors (e.g., empagliflozin, canagliflozin, ertugliflozin)
  • For Type 2 Diabetes: Metformin, GLP-1 receptor agonists, DPP-4 inhibitors, sulfonylureas, insulin, thiazolidinediones, alpha-glucosidase inhibitors, meglitinides.
  • For Heart Failure: ACE inhibitors/ARBs/ARNI, beta-blockers, MRAs, diuretics.
  • For Chronic Kidney Disease: ACE inhibitors/ARBs, finerenone.
