Product Name:
CAS Number:
For the treatment of patients with macular edema after retinal vein occlusion, age-related macular degeneration (wet), and diabetic macular edema.
Mode of Action:

Ranibizumab binds to the receptor binding site of active forms of VEGF-A, including the biologically active, cleaved form of this molecule, VEGF110. The binding of ranibizumab to VEGF-A prevents the interaction of VEGF-A with its receptors (VEGFR1 and VEGFR2) on the surface of endothelial cells, reducing endothelial cell proliferation, vascular leakage, and new blood vessel formation.


Ranibizumab is a recombinant humanized IgG1 kappa isotype monoclonal antibody fragment designed for intraocular use. Ranibizumab is a VEGF-A antagonist that binds to and inhibits the biologic activity of active forms of human VEGF-A, including the cleaved form (VEGF110). VEGF-A has been shown to cause neovascularization (angiogenesis) and an increase in vascular permeability, which is thought to contribute to the progression of the neovascular form of age-related macular degeneration (AMD).


Metabolism was not quantified.


The most common toxic effects to the eye are eye pain, vitreous floaters, increased intraocular pressure, conjunctival hemorrhage, intraocular inflammation, and foreign body sensation. Also arterial thromboembolic events have occurred in patients.
