Q

Mechanism: Insulin therapy

A

Binds insulin receptor (TK activity)

  • Liver: Increase glucose stored as glycogen
  • Muscle: Increase glycogen, protein synthesis, K+ uptake
  • Fat: Increase TG storage

Q

Mechanism: Metformin

A

Inhibit hepatic gluconeogenesis and action of glucagon

  • Decreases gluconeogenesis
  • Increases glycolysis
  • Increases peripheral glucose uptake (sensitivity)
