Where is Ranibizumab used?

Ranibizumab is a prescription used for the treatment of certain serious eye conditions such as:

  • Macular edema
  • Age-related macular degeneration
  • Diabetic retinopathy

This is a type of medicine called vascular endothelial growth factor (VEGF). This slows the development of abnormal new blood vessels in the eye. This also lessens the outflow from these blood vessels. The U.S. Food and Drug Administration (FDA) has already approved this prescription.  

How does Ranibizumab work?

In eye conditions, blood vessels from the back of the eye grow abnormally into the macula. These blood vessels may leak or bleed into this area that causes swelling and a rapid reduction in central vision. A substance called vascular endothelial growth factor A (VEGF-A) is responsible for making the blood vessels grow and leak.

Ranibizumab is a monoclonal antibody that has been designed to specifically recognize and bind to VEGF-A. By binding to VEGF-A, this drug blocks the action of this substance which helps to stop the growth and leakage of blood vessels in the eye. The medicine can help improve damaged vision or prevent it from getting worse.
