Taking Your Medication Correctly

To get the most benefit from your medication, take it exactly as directed by your doctor. Carefully read all the information provided with your prescription, and follow the instructions closely. You can take this medication with or without food, but be sure to swallow the tablet whole. Do not chew, break, or crush it.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Saxagliptin is a highly selective, reversible, competitive dipeptidyl peptidase-4 (DPP-4) inhibitor. It slows the inactivation of incretin hormones (glucagon-like peptide-1 [GLP-1] and glucose-dependent insulinotropic polypeptide [GIP]), thereby increasing their concentrations and enhancing their effects. This leads to increased glucose-dependent insulin secretion from pancreatic beta cells and decreased glucagon secretion from pancreatic alpha cells, resulting in improved glycemic control.

Precautions & Cautions

It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication.

If you experience low blood sugar, do not operate a vehicle, as this increases your risk of being involved in an accident. Monitor your blood sugar levels as directed by your doctor to ensure timely interventions.

Regular blood tests, as scheduled by your doctor, are crucial to assess your health. Discuss any concerns or questions you may have with your doctor.

Be aware that stress, such as fever, infection, injury, or surgery, can affect blood sugar control. Additionally, changes in physical activity, exercise, or diet may also impact your blood sugar levels.

Before consuming alcohol, consult with your doctor to understand the potential effects on your condition. Adhere to the diet and exercise plan recommended by your doctor to maintain optimal health.

Note that this medication has been associated with a severe pancreas problem, known as pancreatitis, which can be life-threatening. If you have any questions or concerns, discuss them with your doctor.

If you are pregnant, planning to become pregnant, or are breastfeeding, inform your doctor. It is crucial to discuss the benefits and risks of this medication to both you and your baby to make an informed decision.

Overdose Information

Overdose Symptoms:

  • Hypoglycemia (if taken with sulfonylurea or insulin)
  • Gastrointestinal upset
  • Other exaggerated adverse effects

What to Do:

Call 911 or Poison Control (1-800-222-1222). Treatment is supportive. Saxagliptin and its active metabolite are dialyzable.

Drug Interactions

🔴

Major Interactions

  • Strong CYP3A4/5 inhibitors (e.g., ketoconazole, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin) - reduce saxagliptin dose to 2.5 mg once daily.
🟡

Moderate Interactions

  • Moderate CYP3A4/5 inhibitors (e.g., diltiazem, erythromycin, fluconazole, verapamil) - reduce saxagliptin dose to 2.5 mg once daily.

Monitoring

đŸ”Ŧ

Baseline Monitoring

HbA1c

Rationale: To establish baseline glycemic control and confirm diagnosis of type 2 diabetes.

Timing: Prior to initiation

Renal function (eGFR or CrCl)

Rationale: To determine appropriate starting dose and identify need for dose adjustment.

Timing: Prior to initiation

Liver function tests (ALT, AST, bilirubin)

Rationale: To assess baseline hepatic health, though not a primary concern for saxagliptin.

Timing: Prior to initiation

📊

Routine Monitoring

HbA1c

Frequency: Every 3-6 months

Target: Individualized, typically <7% for most adults

Action Threshold: Above target range, consider dose adjustment or add-on therapy

Renal function (eGFR or CrCl)

Frequency: Annually, or more frequently in patients with impaired renal function or risk factors

Target: Maintain appropriate CrCl for dose

Action Threshold: Decline in renal function requiring dose adjustment

đŸ‘ī¸

Symptom Monitoring

  • Symptoms of hypoglycemia (if used with sulfonylurea or insulin): sweating, tremor, dizziness, confusion, hunger
  • Symptoms of pancreatitis: severe, persistent abdominal pain, radiating to the back, with or without vomiting
  • Symptoms of heart failure: unusual shortness of breath, rapid weight gain, swelling of ankles/feet
  • Symptoms of severe and disabling arthralgia: severe joint pain
  • Symptoms of bullous pemphigoid: new or worsening blisters or erosions on the skin
  • Symptoms of hypersensitivity reactions: rash, urticaria, angioedema

Special Patient Groups

🤰

Pregnancy

Use during pregnancy is generally not recommended unless the potential benefit justifies the potential risk to the fetus. Limited human data. Animal studies show potential for fetal harm at high doses.

Trimester-Specific Risks:

First Trimester: Potential for fetal harm based on animal data, but human data are limited.
Second Trimester: Potential for fetal harm based on animal data, but human data are limited.
Third Trimester: Potential for fetal harm based on animal data, but human data are limited.
🤱

Lactation

Not recommended during breastfeeding. Saxagliptin and its active metabolite are excreted in the milk of lactating rats. It is unknown if it is excreted in human milk. Due to potential for serious adverse reactions in breastfed infants, 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., hypoglycemia) in breastfed infants.
đŸ‘ļ

Pediatric Use

Safety and effectiveness have not been established in pediatric patients. Not recommended for use in patients younger than 18 years of age.

👴

Geriatric Use

No dose adjustment is required based on age alone. However, older patients are more likely to have decreased renal function, so renal function should be assessed prior to initiation and periodically thereafter.

Clinical Information

💎

Clinical Pearls

  • Saxagliptin has been associated with an increased risk of heart failure hospitalization in patients with established cardiovascular disease or multiple risk factors for heart failure (as observed in the SAVOR-TIMI 53 trial). Assess patients for heart failure risk factors before initiating.
  • Cases of acute pancreatitis, sometimes fatal, have been reported. Patients should be advised to discontinue saxagliptin and seek medical attention if they develop symptoms of pancreatitis.
  • Severe and disabling arthralgia (joint pain) has been reported. Consider discontinuing the drug if this occurs.
  • Bullous pemphigoid, a serious blistering skin condition, has been reported. Discontinue if bullous pemphigoid is suspected.
  • Risk of hypoglycemia is increased when co-administered with a sulfonylurea or insulin; a lower dose of sulfonylurea or insulin may be required.
🔄

Alternative Therapies

  • Other DPP-4 inhibitors (e.g., sitagliptin, linagliptin, alogliptin)
  • GLP-1 receptor agonists (e.g., liraglutide, semaglutide)
  • SGLT2 inhibitors (e.g., empagliflozin, canagliflozin)
  • Sulfonylureas (e.g., glipizide, glyburide)
  • Meglitinides (e.g., repaglinide)
  • Thiazolidinediones (e.g., pioglitazone)
  • Insulin
  • Metformin
