Razumab 2.3mg injection, contains the active ingredient Ranibizumab. It is an anti-neovascularisation agent in the class of medications called vascular endothelial growth factor A (VEGF-A) antagonists. It is used in adults to treat several eye diseases causing vision impairment. It is used to treat wet age-related macular degeneration (AMD, a persistent eye disease that causes loss of the ability to see straight ahead and may make it more difficult to read, drive, or perform other daily activities). Razumab 2.3mg injection is also used to treat myopic choroidal neovascularization (mCNV; a complication in near-sighted people where new blood vessels can grow in the back of the eye), and to treat macular edema after retinal vein occlusion (an eye disease caused by blockage of blood flow from the eye that leads to blurry vision and vision loss). It is also used to treat diabetic macular edema (an eye disease caused by diabetes that can lead to vision loss) and diabetic retinopathy (damage to the eyes caused by diabetes).
