Mechanism of action

Ranibizumab binds to and neutralizes VEGF-A, a key driver of pathological neovascularization and vascular permeability in retinal diseases. By inhibiting VEGF-A signaling, it reduces abnormal vessel formation, decreases retinal edema, and slows vision loss in conditions characterized by excessive angiogenesis. The intravitreal route delivers the drug directly to the posterior segment of the eye for local therapeutic effect.
