Mechanism of action
NPH (Neutral Protamine Hagedorn) insulin is a suspension of insulin crystals complexed with protamine, which slows insulin absorption and extends its duration of action to 10-16 hours. It mimics the basal insulin secretion of the pancreas, providing steady glucose control between meals and overnight. NPH insulin acts on insulin receptors throughout the body to increase glucose uptake in muscle and adipose tissue while suppressing hepatic glucose production.
