Last edited 12/2020 and last reviewed 10/2021

Pioglitazone is known to improve insulin sensitivity, glycaemic control, hypertension and dyslipidaemia in people with T2DM (1).

Pioglitazone:

  • decreases fasting and postprandial plasma glucose levels by improving the sensitivity of hepatic and peripheral (muscle) tissue to insulin

A systematic review concluded that "Pioglitazone reduced or delayed the development of T2DM in people at increased risk of T2DM compared with placebo (low-certainty evidence) and compared with no intervention (moderate-certainty evidence). .. unclear whether the effect of pioglitazone is sustained once discontinued. Pioglitazone compared with metformin neither showed advantage nor disadvantage regarding the development of T2DM in people at increased risk (low-certainty evidence)."
