Mechanism of action

NPH (Neutral Protamine Hagedorn) insulin is a suspension of insulin crystals complexed with protamine, which slows insulin absorption from subcutaneous tissue compared to regular insulin. This intermediate duration of action (peak effect 4-8 hours, duration 10-16 hours) makes it suitable for twice-daily dosing regimens in diabetes management. It mimics endogenous insulin secretion by promoting glucose uptake in muscle and adipose tissue while suppressing hepatic glucose production.
