Insulin detemir: mode of prolonging action • Self association (hexameric) • Fatty acid side chains bind to albumin in injection depot • Albumin binding in circulation Protracted absorption ‘Buffering’ effect and minor contribution to protraction

Insulin detemir provides: • A prolonged and reproducible time-action profile • Less variability in comparison to NPH insulin • Improved glycaemic control compared with NPH insulin • A risk reduction for nocturnal hypoglycaemia compared with NPH insulin • Less weight gain
