Invokana Mechanism of Action

Kidney Heart and Blood Drop

Prescribing Information

Great Britain Northern Ireland

Mode of Action

  • Invokana is an SGLT2 inhibitor1
  • SGLT2 is a sodium-glucose co-transporter expressed in the proximal renal tubules, and is responsible for 90% of glucose reabsorption1,2
  • SGLT2 inhibitors act independently of β-cell function or insulin sensitivity – removing excess blood glucose by increasing urinary glucose excretion3
  • This also results in a loss of excess calories and water – which is why Invokana may also reduce weight and blood pressure4,5

Weight loss and blood pressure reduction are
additional benefits only and not licensed indications.

  • SGLT2s are responsible for 90% of glucose reabsorption, making it an attractive target for inhibition.6
  • SGLT2 inhibitors act independently of β-cell function or insulin sensitivity – removing excess blood glucose by increasing urinary glucose excretion.3 This also results in a loss of excess calories and water – which is why Invokana may also reduce both weight and blood pressure.4,5
  • Invokana increases estimated urinary glucose excretion ranging from 77–119 g per day. This translates to an equivalent loss of 308-476 kcal/day.[Results from Phase I studies of urinary glucose excretion in patients with type 2 diabetes]

This leads to:

  • Improved glycaemic control and a reduction in HbA1c1
  • A loss of calories and therefore a reduction in body weight1
  • A mild osmotic diuresis, with the diuretic effect leading to a reduction in systolic blood pressure1

Weight loss and blood pressure reduction are additional benefits only and not licensed indications.

How Invokana delivers renal benefits

invokana benefits on renal
  • In type 2 diabetes, SGLT2 is overexpressed – contributing to glomerular hyperfiltration. Inhibiting SGLT2 may, therefore, reduce hyperfiltration and lead to decreases in intraglomerular pressure.7,8
