Aflibercept is a recombinant fusion protein that acts as a vascular endothelial growth factor (VEGF) inhibitor, used primarily for the treatment of neovascular (wet) age-related macular degeneration (AMD), diabetic macular edema, and other retinal vascular diseases. It is approved for intravitreal use in ophthalmology.
Pharmacokinetics
Pharmacokinetic parameters after a single intravitreal injection of aflibercept 2 mg in adult patients with neovascular AMD; population includes both sexes, typically age >50 years.
