Ketorolac is a type of medication that belongs to the nonsteroidal anti-inflammatory drug (NSAID) class. It is commonly used to treat moderate to severe pain, inflammation, and swelling. It works by blocking certain substances in the body that cause pain and inflammation. Antibiotics are used to treat bacterial infections, antivirals are used to treat viral infections, and steroids are used to treat allergic reactions and autoimmune disorders. Therefore, options A, B, and D are incorrect as they do not have the same mechanism of action as ketorolac.
