Pranoprofen, brand name Niflan, belongs to a class of medications called non steroidal anti-inflammatory drugs (NSAID). It can be used to treat inflammation, keratitis, conjunctivitis and blepharitis after eye surgery. Its mechanism of action is the inhibition of inflammatory prostaglandin synthesis. Prostaglandins are types of lipids which are produced at the site of injury or damaged tissue as part of the body`s response to the injury. They are responsible for inflammation. However, the main ingredient in this ophthalmic medicine is a non-steroidal anti-inflammatory drug, and by blocking the formation of prostaglandins, it can alleviate eye inflammation caused by keratitis, blepharitis and other conditions. Patients who have undergone surgery on the eyes may also be given it to prevent the occurrence of eye inflammation.
