Dipeptidylpeptidase-4 (DPP-IV) Inhibitors (Gliptins)



Alogliptin, Linagliptin, Saxagliptin, Sitagliptin, Vildagliptin


  Issues for Surgery


Increased risk of post-operative infection and delayed wound healing due to poor glycaemic control if omitted.

Potential for hypoglycaemia when taken concomitantly with other blood glucose lowering medicines and continued during nil by mouth period.

Combination products containing Metformin – risk of lactic acidosis if continued (see Interaction(s) with other Common Medicines used in the Perioperative Period and Further Information).

Combination products containing Dapagliflozin – risk of diabetic ketoacidosis (DKA), volume depletion, hypotension and/or electrolyte disturbances if continued (see Further Information).


  Advice in the Perioperative period


Elective and Emergency Surgery

DDP-IV Inhibitors should be taken as normal the day prior to surgery (including combination products)1.

Morning or Afternoon Surgery
Continue1, 2.

EXCEPT:

  • Vipodomet® – contains alogliptin + metformin
  • Jentadueto® – contains linaglitpin + metformin
  • Komboglyze® – contains saxagliptin + metformin
  • Janumet® – contains sitagliptin + metformin
  • Eucreas® – contains vildagliptin + metformin


  • Qtern® – contains saxagliptin + dapagliflozin (see Sodium Glucose Co-transporter 2 (SGLT-2) Inhibitors monograph).

Consideration should be given to prescribing the components of combination products as separate medicines perioperatively.

Perioperative Considerations

Commence variable rate intravenous insulin infusion (VRIII) perioperatively where indicated (see Further Information) and withhold DPP-IV Inhibitor during VRIII treatment1.

Ensure emergency treatment of hypoglycaemia is prescribed i.e. Glucogel® and 20% dextrose. Rapid also be prescribed1, 2.

Post-operative Advice

Restart once eating and drinking normally and VRIII (where applicable) has been stopped1.

  Interaction(s) with Common Anaesthetic Agents


None2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.


  Interaction(s) with other Common Medicines used in the Perioperative Period


None for products containing DPP-IV Inhibitor alone2, 3, 5, 7, 10, 12.

Iodinated Contrast Agents

Caution with combination products containing metformin and concomitant use of iodinated contrast agents4, 6, 8, 13 – see Metformin monograph.

Non-Steroidal Anti-inflammatory Drugs (NSAIDs)

Caution with combination products containing metformin and concomitant use of NSAIDs4, 6, 8, 11, 13 – see Metformin monograph.


  Further Information


Lactic Acidosis

Risk of lactic acidosis with combination products containing metformin4, 6, 8, 11, 13 – see Metformin monograph.

DKA, Volume Depletion, Hypotension and/or Electrolyte Imbalance

Risk of DKA, volume depletion, hypotension and/or electrolyte imbalance with combination product containing dapagliflozin9 – see Sodium Glucose Co-transporter 2 (SGLT-2) Inhibitors monograph.

VRIII

Patients with a planned short starvation period (no more than one missed meal in total) should be managed by modification of their usual diabetes medication, avoiding VRIII wherever possible. Patients expected to miss more than one meal should have VRIII1.
