Acular is a prescription strength non-steroidal anti-inflammatory (NSAID) ophthalmic solution and is used to relieve post-surgical pain, stinging and burning from procedures such as corneal refraction and cataract surgeries. Acular is also used to treat conjunctivitis, also known as pink eye. Ketorolac or ketorolac is the generic version of Acular. The Acular solution works by blocking the production of prostaglandin synthesis. Prostaglandins are involved in causing pain and inflammation, among other things. Acular effectively blocks the pain and inflammation through deterring prostaglandin synthesis.
