Mechanism of action

Ranibizumab is a recombinant humanized monoclonal antibody fragment that binds and neutralizes all active forms of VEGF-A, a key driver of pathological neovascularization and vascular permeability in retinal diseases. By inhibiting VEGF signaling, it reduces fluid accumulation in the macula and slows progression of vision loss. The 'treat and extend' regimen involves variable dosing intervals based on disease activity to optimize treatment burden and efficacy.
