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 fluid accumulation in the retina and slows progression of vision-threatening conditions. The intravitreal injection route delivers the drug directly to the posterior segment of the eye for local therapeutic effect.
