Aflibercept is a biologic medication used to treat various eye conditions, such as age-related macular degeneration (AMD) and diabetic macular edema, as well as certain cancers. Aflibercept is a fusion protein that binds to vascular endothelial growth factor (VEGF), preventing it from stimulating abnormal blood vessel growth and fluid leakage in the eye. This helps reduce vision loss and swelling associated with these conditions. Aflibercept is typically administered through intravitreal injection directly into the eye by a healthcare professional. It is also used in oncology to treat certain types of cancer by inhibiting VEGF to reduce tumor growth and spread.
