Ranibizumab (RG-6321) (anti-VEGF) is a humanized anti-VEGF monoclonal antibody fragment and can recognize all VEGF-A isoforms (VEGF110, VEGF121, and VEGF165). Ranibizumab (anti-VEGF) slows vision loss in vivo and is used for wet age-related macular degeneration (AMD) research.

Ranibizumab (RG-6321) is a humanized anti-VEGF monoclonal antibody fragment (IgG antigen-binding fragment (Fab-Y0317). Ranibizumab (0.0625-0.25 mg/ml; 72 hours) results in increased necrosis and apoptosis at in rat retinal cell cultures.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Studies in monkeys demonstrates that after a single intravitreal administration, Ranibizumab can distribute rapidly to the retina (6–24 h). Ranibizumab can rapidly penetrate through the retina to reach the choroid, just 1 h after intravitreal administration in rabbits.
In a study comparing the pharmacokinetics of 0.5 mg of intravitreal Ranibizumab with 1.25 mg of intravitreal Bevacizumab in the rabbit, the vitreous half-life of Ranibizumab is 2.88 days, shorter than the Bevacizumab half-life of 4.32 days. Peak concentrations in the aqueous humor of the treated eye at 3 days following treatment are 37.7 μg/ml for Bevacizumab and 17.9 μg/ml for Ranibizumab, respectively.
