    • increases insulin sensitivity and decreases glucose production by the liver. 
    • does not cause weight gain (and may cause some weight loss).
    • does not cause hypoglycaemia.
  • Notable side effects of metformin:
    • Gastrointestinal symptoms, including pain, nausea and diarrhoea
    • Lactic acidosis (e.g., secondary to acute kidney injury, trauma, surgery)
    • Can lower B12 so check pre-treatment and annually
  • Contraindications
    • eGFR < 30
    • liver failure, heart failure, excess alcohol
SGLT-2 Inhibitors
  • Dapagliflozin (Forxiga) 10mg
    • The sodium-glucose co-transporter 2 protein is found in the proximal tubules of the kidneys. It acts to reabsorb glucose from the urine back into the blood.
    • SGLT-2 inhibitors block the action of this protein, causing more glucose to be excreted in the urine.
    • Loss of glucose in the urine lowers the HbA1c, reduces the blood pressure, leads to weight loss and improves heart failure
    • Can cause hypoglycaemia when used with insulin or sulfonylureas.
    • Also licensed for heart failure and chronic kidney disease.
  • Notable side effects of SGLT-2 inhibitors include:
    • Glycosuria (glucose in the urine)
    • Increased urine output and frequency
    • Genital and urinary tract infections (e.g., thrush)
    • Weight loss

    • It does not typically cause hypoglycaemia.
  • Notable side effects of pioglitazone include:
    • Weight gain
    • Heart failure
    • Increased risk of bone fractures
    • A small increase in the risk of bladder cancer
Sulfonylureas
  • Gliclazide (Diamicron) MR oral 30-120mg OD
    • Sulfonylureas stimulate insulin release from the pancreas.
  • Notable side effects of sulfonylureas:
    • Weight gain
    • Hypoglycaemia
DPP-4 Inhibitors and GLP-1 Mimetics

Incretins are hormones produced by the gastrointestinal tract. They are secreted in response to large meals and act to reduce blood sugar by:

  • Increasing insulin secretion
  • Inhibiting glucagon production
  • Slowing absorption by the gastrointestinal tract 

The main incretin is glucagon-like peptide-1 (GLP-1). Incretins are inhibited by an enzyme called dipeptidyl peptidase-4 (DPP-4).

DPP-4 inhibitors
  • Sitagliptin (Januvia) 100mg oral od (eGFR > 50), 50mg (eGFR 30-50), 25mg (eGFR < 30)
    • blocks the action of DPP-4, allowing increased incretin activity.
    • does not cause hypoglycaemia.
  • Notable side effects of DPP-4 inhibitors:
    • Headaches
    • Low risk of acute pancreatitis
 GLP-1 mimetics
  • Dulaglutide (Trulicity) 0.75mg s/c weekly increasing to 1.5mg
    • imitate the action of GLP-1.
  • Notable side effects of GLP-1 mimetics:
    • Reduced appetite
    • Weight loss
    • Gastrointestinal symptoms, including discomfort, nausea and diarrhoea
Insulin
  • Rapid-acting insulins – insulin aspart – (e.g., NovoRapid) start working after around 10 minutes and last about 4 hours.
  • Short-acting insulins – regular (e.g., Actrapid) start working in around 30 minutes and last about 8 hours.
  • Intermediate-acting insulins – insulin protamine – (e.g., Humulin N) start working in around 1 hour and last about 16 hours.
  • Long-acting insulins – insulin glargine (e.g., Optisulin, Toujeo, Lantus) start working in around 1 hour and last about 24 hours or longer.
  • Combinations insulins contain a rapid-acting and intermediate-acting insulin (Rapid:Intermediate).
