Introduction to Lucentis
Brief Overview of Lucentis (Ranibizumab)
Lucentis, known by its generic name Ranibizumab, is a significant medical advancement in the treatment of various eye conditions. It is primarily used for wet age-related macular degeneration (wet AMD), diabetic macular edema (DME), diabetic retinopathy (DR), myopic choroidal neovascularization (mCNV), and macular edema following retinal vein occlusion (RVO). Since its introduction in 2006, Lucentis has been administered in over 12 million doses, highlighting its widespread acceptance and effectiveness.
Role in Treating Eye Conditions
Lucentis plays a crucial role in managing and treating several serious eye conditions that can lead to vision loss. In wet AMD, it helps in slowing down the progression of the disease and in some cases, improving vision. For diabetic patients suffering from DME and DR, Lucentis is instrumental in reducing macular edema and improving visual acuity. It is also effective in treating mCNV and RVO, conditions that can severely impact vision if left untreated.
What is Lucentis?
Detailed Description of Lucentis
Lucentis is an FDA-approved injectable medication designed to treat eye diseases that cause vision loss. It belongs to a class of drugs known as anti-VEGF (Vascular Endothelial Growth Factor) therapy. Lucentis works by inhibiting the growth of abnormal blood vessels in the eye and reducing vascular permeability, which can lead to fluid leaks that damage the retina and impair vision.
The Class of Drugs it Belongs To (Anti-VEGF Therapy)
As an anti-VEGF drug, Lucentis is part of a treatment category that targets the VEGF protein, which stimulates the growth of new blood vessels. By blocking this protein, Lucentis helps prevent the formation of abnormal blood vessels in the eye, a common cause of vision loss in conditions like wet AMD and diabetic eye diseases.
How it Works in the Body
Lucentis is administered directly into the eye through an intravitreal injection. Once injected, it binds to the VEGF protein, inhibiting its activity. This action reduces the growth of abnormal blood vessels and decreases fluid leakage in the retina, thereby helping to preserve and sometimes improve vision in patients with retinal disorders.
