Mechanism of action

Human insulin is a recombinant peptide hormone that mimics endogenous insulin secreted by pancreatic beta cells. It binds to insulin receptors on muscle, fat, and liver cells, triggering intracellular signaling cascades that increase glucose transport into cells and promote glycogen synthesis while inhibiting gluconeogenesis. This restores glucose homeostasis in patients with insufficient endogenous insulin production or insulin resistance.
