Nepafenac is primarily used in ophthalmology as a nonsteroidal anti-inflammatory drug (NSAID) to treat pain and inflammation following cataract surgery. It works by inhibiting the production of prostaglandins, which are chemicals in the body that cause inflammation and pain. By reducing these symptoms, Nepafenac helps promote faster and more comfortable recovery post-surgery. Additionally, it is sometimes prescribed to manage ocular conditions such as uveitis, where inflammation of the eye needs to be controlled. Its prodrug formulation allows for better penetration into ocular tissues, making it highly effective for targeted treatment in the eye.
