Some common nonsteroidal anti-inflammatory drugs include aspirin, ibuprofen and naproxen, according to WebMD. These NSAIDs are available for purchase without a prescription. Common prescription brand NSAIDs include Celebrex, Feldene and Voltaren.
The chemical makeup of NSAIDs differs, according to MedicineNet. Each drug's potency, how long it takes to work, how the body eliminates it and potential side effects differentiate one class of anti-inflammatory from another.
NSAIDs are used to reduce pain, fever and inflammation, notes WebMD. Some common NSAIDs, such as ibupropen and naproxen, are used to minimize menstrual bleeding. Selective COX-2 inhibitors, such as Celebrex, result in fewer ulcers and less bleeding. Aspirin is routinely used to stop the clotting of blood, in turn preventing the occurrence of a heart attack or stroke.
