Drug Guide
Bexagliflozin
Classification
Therapeutic: Antidiabetic agent
Pharmacological: SGLT2 inhibitor
FDA Approved Indications
- Type 2 diabetes mellitus
Mechanism of Action
Bexagliflozin inhibits the sodium-glucose co-transporter 2 (SGLT2) in the proximal renal tubules, reducing glucose reabsorption and increasing urinary glucose excretion, thereby lowering blood glucose levels.
Dosage and Administration
Adult: Typically, 20 mg once daily, with or without food. Dose adjustments may be necessary based on renal function.
Pediatric: Not approved for pediatric use.
Geriatric: Use with caution; consider renal function and overall health status.
Renal Impairment: Adjust dose or use with caution in patients with impaired renal function; contraindicated in severe renal impairment.
Hepatic Impairment: Limited data; use caution and monitor closely.
Pharmacokinetics
Absorption: Rapid absorption with peak plasma concentrations in approximately 1-2 hours.
Distribution: Moderate volume of distribution; highly protein-bound.
Metabolism: Primarily metabolized via glucuronidation.
Excretion: Excreted mainly in urine (as unchanged drug and metabolites).
Half Life: Approximately 10-13 hours.
Contraindications
- Severe renal impairment (eGFR <30 mL/min/1.73 m²)
- End-stage renal disease
- Dialysis
Precautions
- Monitor renal function regularly.
- Risk of diabetic ketoacidosis (DKA).
- Use with caution in elderly, dehydrated patients, or those with hypotension.
Adverse Reactions - Common
- Urinary tract infections (Common)
- Genital mycotic infections (Common)
- Increased urination (Common)
Adverse Reactions - Serious
- Diabetic ketoacidosis (DKA) (Uncommon but serious)
- Serious urinary tract infections or pyelonephritis (Rare)
- Hypotension (Uncommon)
Drug-Drug Interactions
- Diuretics (potentiation of hypotension)
- Insulin and other antidiabetics (risk of hypoglycemia)
Drug-Food Interactions
N/ADrug-Herb Interactions
N/ANursing Implications
Assessment: Monitor blood glucose, renal function, volume status, and signs of DKA.
Diagnoses:
- Risk for hypoglycemia
- Risk for infection
- Risk for dehydration
Implementation: Administer once daily, monitor renal function periodically, educate patient on signs of DKA and infections.
Evaluation: Assess blood glucose control, renal function, and for any adverse reactions.
Patient/Family Teaching
- Take medication exactly as prescribed.
- Report symptoms of urinary tract infections, genital infections, or DKA.
- Maintain hydration.
- Monitor blood glucose regularly.
Special Considerations
Black Box Warnings:
- Risk of ketoacidosis, which can be life-threatening.
Genetic Factors: No specific genetic considerations currently recognized.
Lab Test Interference: May affect serum blood glucose measurements; use appropriate testing methods.
Overdose Management
Signs/Symptoms: Severe dehydration, hypotension, ketoacidosis.
Treatment: Discontinue medication, provide supportive care, rehydrate with intravenous fluids, and monitor blood glucose and acid-base status.
Storage and Handling
Storage: Store at room temperature, protect from moisture and light.
Stability: Stable up to the expiration date when stored properly.
